THE EARLIEST FIXED BIAS AC100s - 1965

The "100W Amplifier"

Black transformers, but no brimistor - June, July and August 1965

100 Watt Amp Schematic

Dated 30th May 1965.

Around two hundred and ninety "100W Amplifiers" were made at the Burndept works in Erith in June/July/August of that year, large numbers of which were shipped to the Thomas Organ Co. for distribution in the USA - mostly in air shipments. A small proportion of amps were retained, however, by JMI for sale in the UK and Europe. Most of the amps sent to the USA seem to have accompanied 4x12" cabs - ie. the AC100 SDL.

A schematic was included by Thomas Organ in its repair dossiers, along with a parts list and schematics of the cathode biased AC80/100 and the newer AC100 Mark 2 (the AC100/2 with brimistor).

The fixed bias amps ran much much cooler than the AC80/100s, even if the bias was well on the low side for the EL34s, and delivered a true 100W.

  • early fixed bias ac100, mains transformer
  • serial number in the 500s, chassis front
  • serial number 520
serial number in the 600s (03), chassis top

More of a note than anything: four chassis survive with long triangles of purple/russet sticky tape behind the mains transformer. Chassis nos 11xx, 1201, 1237 and 1384. What is?

The Who, Copenhagen 1965

Repeated from the , The Who in Copenhagen, 25 September 1965, with six AC100s. The amps are most likely the new fixed bias "100W Amplifier" - one can tell they are not cathode biased by the presence of two screws along the top edge of the backboard. Cathode biased amps had only one.

  • Vox AC100 early fixed bias ac100, back

  • early fixed bias ac100, chassis underside centre
  • early fixed bias ac100, chassis underside right
  • early fixed bias ac100, mains transformer

Probably one of the earliest "100W amplifiers" surviving. The serial plate is gone but the chassis number is 11xx, which suggests closeness in terms of date to the latest cathode bias amps listed on the serial numbers 320-430s page. The latest of those, going by the chassis, is 1135. Transformers are the new black units, there is no brimistor (and no holes on the chassis for the stand-offs required), resistors are by and large the white carbon composites ("carbon comps") made by Erie. Electrolytic capacitors are or were TCCs, and the capacitors in the signal path (in the preamp) are gold WIMA tropyfoils. On the underside - the last four pictures - note the large (2W) plate resistors on the left of the board, laid out at 90 degrees to the other components, and the fixed bias network in the centre of the board. Two new dark brown resistors stand in place of the zener diodes specified in the schematic. The wiring of the output valve bases has also been adjusted to accommodate new resistors (the square white ones) that serve to drop the screen voltage slightly. A great amp.

Chassis no. 1207, serial plate no. 502. Amp and cab have been together since 1967, and probably left the Vox factory together July-ish 1965. One can see in the pictures of the amp above that one of the pots has the stamped code DM = April 1965, and that two of the TCC capacitors have codes WB and WD, respectively February and April 65. Both are in fine condition. Note for instance the original wiring and stapling in the speaker cabinet, and the intactness of the preamp. This amp had no brimistor. The single hole (by the choke) is new. As in the case of the amp with chassis 11xx (above on this page), the choke has the code 66429, doubtless having been supplied by the company that made the black-shrouded mains and output transformers, which are later bear the numbers 66775 and 66776. One of the earliest original amp and cab sets surviving.

From this point the black-shrouded transformers have code numbers stamped on their underside (66775 for the mains, and 66776 for the output)

Chassis number 1237. This was originally a fixed bias AC100 - black shrouded transformers, "flying" 330K grid resistors in the preamp (among other signs of fixed bias arrangement), and a chassis number consonant with a serial number in the lowish 500s. At some stage, probably in the 1990s, the power section of the amp was converted to cathode bias. Despite the changes, a very nice amp. The box is likely to be original to the amp - note the two fixing points along the top edge of the back board. The box of an amp with serial no. 500s_01 would only have had one.

Chassis number 1201. A few replaced caps in the preamp, and some new zener diodes in the power section, but otherwise good. The manufacturer's code 66775 is stamped on the underside of the mains transformer. The output transformer is unstamped. As in a number of early fixed bias amps, the feeds from the output transformer are curled round the edge of the chassis rather than being passed through the hole in the preamp. Note the Mullard BY100 ("top hat") rectifier in the bias circuit. Both XLR and mains connector have been replaced on the back panel. The screw holes that remain indicate that the speaker output, certainly, was a rectangular XLR. Further inspection will reveal whether the mains connector was an Amphenol (held by three screws) or a rectangular Cannon LNE-11 (held by two). The cover, without a legend, is original.

A Cannon XLR speaker connector installed. Removing the IEC connector showed that an Amphenol was originally there (a replacement now fitted). The pots have the code "DM" = April 1965; and the Daly filter capacitor "WD" = April 1965 too. Note the suppressor cap (Radiospares) for the mains switch, visible behind the panel fuseholder - installed by Vox in amps intended for the US market.

Chassis number 1204. The Amphenol mains connector remains. Possibly originally two Cannon XLR speaker connectors; only one remains. The preamp is intact. Mains transformer is original, though its top cover has been removed. The output transformer may be from a later AC100 (to be determined), as there are solder tags on its underside rather than flying leads. Date code the original filter cap. is "WD" = April 1965.

The remaining original Mullard yellow-print EL34 has the code B5D4 = Blackburn Factory, 1965, last week of April. The other three valves are GE branded Mullards.

Pics shortly after the arrival of the amp in the UK. Note the Werth "Surgistor" under the lip of the control panel by the voltage selector. The amp seems to have been repaired at a Thomas Organ repair shop, where a replacement slightly later AC100 output transformer was added, and some new components here and there. The shroud was taken off the mains transformer. Very probably the repairman followed the AC100 Mk2 schematic (rather than that of the "100W Amplifier"), supplying the surgistor as a stand-in for a brimistor. An AC50 has also been spotted (thanks to Tom for the info) with a Werth Surgistor added in the same position.

Additional note: the treble and bass pots (1M) have the date codes "DM" = April 1965. See the pic above. The volume pot (500K), which turned out to be defective and had to be removed, has the code "AM" = January 1965. Pic below.

Chassis no. 1219. Serial no. 531. Another early "100W amplifier", ie. without a brimistor (note the absence of holes in the chassis for the standoffs). Evidently close in terms of components and arrangement to the amps above - note for instance the choke, and the large grey/blue Radio Spares paper capacitor across the power tagboard on the underside of the chassis, which has been treated (zinc passivated), a practice later dropped.

Three matching yellow-print Mullard EL34s came with the amp, all XF2s - the latest date code is B5E5 - last week of May 1965. The code of the non-matching GE valve is B5h6 - August 1965, which probably indicates that an EL34 blew fairly early on and was replaced in late '65. Date codes of the original capacitors that remain are VK and WD, respectively December 1964 and April 1965. The amp probably left the factory in June/July of that year.

The other amps noted on this page as being in the UK were purchased in the USA and only shipped back relatively recently. A few replacement components here and there - capacitors, plate resistors, mains switch, and one pot - but otherwise not much changed. Note the presence of the suppressor capacitor (not on the schematic) up by the mains switch/indicator lamp. The cap. was introduced primarily with a view to helping amps in the US market. Clearly it was added to all early "100W Amplifiers". The mains transformer has the part-code stamped on its underside but not the output. Thanks to Robert for the pictures.

Advertised on Gbase in late 2009/early 2010. Inverting the mandatory blurry picture of the serial number plate in Photoshop seems to give 6xx. Some sort of standby circuit was installed by the owner (fairly easily achieved unobtrusively) - a sensible precaution as this, if memory serves, was someone's gigging amp. The cabinet is a later Vox Sound cabinet from the 1970s, with handles let into the sides, and tell-tale yellow paint on the screws.

Chassis number 1348, so probably a serial number in the high 600s, perhaps low 700s. No brimistor. Note that the Vox logo is composed of separate letters "V O X". One of the three original filter capacitors in the preamp has the code VL = November 1964, a while therefore before this amp was built; another has WA = January 1965. The 470ohm resistor on the output block has the code WD = April 1965; and the choke has the code EW = May 1965. May 1965 is also the date of one of the original Mullard yellow-print ECC82s (the other dates from late '64). The back board is a replacement. The output transformer is the original turned sideways - and has the code stamped in white on the side - see the pictures below.

Chassis number 1384. Sold on ebay in July 2011, and offered again a couple of months later (with new pictures). Nice cosmetic condition. Changes: a replaced mains transformer (and nicely rewired power section), a new fuseholder, some renewed components in the preamp, and the provision of a switch (for changing impedance?) on the back board by the speaker output socket. Although holes are present in the upper chassis, there is no brimistor - the holes in any case are not in the right positions - see below. Note that the warning plaque on the back board is still white.

Chassis no. 14xx. No brimistor. The code on the Woden choke is "EW" = May 1965. The amp has been nicely restored. Its black control plate is from another amp - the original (grey) is in the UK, having been sold on ebay. The box and its back panel fittings were all acquired separately.

A single image, originally posted on the . The text says no brimistor. Note the small tagboard in the preamp for the 330K grid resistors, the large grey Radio Spares 0.22uf in the bias network (underside of amp), the original 1W Erie plate resistors and green TCC caps. The black-shrouded transformers appear to have no stamped numbers on their undersides. XLR sockets for power and speaker.

Chassis no. 1303. New mains socket, but still the original XLR speaker connector. An impedance switch fitted on the back panel. The warning plaque is still white. Note that the new style red plaque had come in by serial no. 748.

A bit of a tangle in the power section - main filter caps have been replaced by pairs of axial caps in parallel. The output transformer is an old replacement. The choke has the code EW = May 1965. The preamp is fairly intact.

Pot codes - see below - "EM" = May 1965. Photos of the codes photographed using a a mirror have been reversed (ie. put the right way round) in Photoshop.
