This is a 1x12 combo broadly based on the Non-Reverb AB763 circuit. It has a 2x6V6 power amp, switchable diode/tube rectifier and optical tremolo. As well as the clean vibrato channel it has a modded 'lead' channel with much more gain. Mercury Magnetics transformers and choke.

It also has a variety of switches that tailor the sound:

The main vibrato channel has the bright cap on the volume pot on a pull switch - it's out of the circuit if you push the knob in;

Negative feedback switch on the back panel;

Gain switch on the push-pull knob for the lead channel; this cuts out the EQ;

Mod switches on the back panel which change the response (slightly!).


Master volume on the back panel - LarMar type so more-or-less out of circuit when wound up.


Bias points to easily fit new valves.

Pre out and Power in sockets, but (fair warning) these aren't configured as a loop as such - you'd need a 'dumbleator' or 'Klein-u-lator' type thing to interface (some) effects.


If you buy and collect, you can have a vibrato foot switch and cable with it.


The original C-Rex speaker is long gone, and currently fitted is the excellent-sounding cast-frame Goodmans you can see in some of the photos. It has been reconed with a V30 cone and coil, so is more than capable of handling the power from the amp.


Amusing patches on top left and bottom right - if they really put you off, they can be removed (before sale by me, or indeed after sale by you)...


I bought this in 2016 from the original builder, and his advert had this text:

Modded AB763 no reverb circuit in blonde and oxblood combo with C Rex 12" speaker. 
Mercury Magnetics Deluxe Reverb iron.
Small chassis build so smaller than a DR.
25w from 2xJJ6V6. Tube/diode rectifiers. LarMar PPIMV. 4/8/16 impedance switch. 
D style Normal channel (lots of gain) virtually standard Vibrato channel. 


PS: I'll try to add some better photos!
