seeking schematics for English Club Model
« on: December 30, 2019, 08:08:22 AM »
I'm in search of schematics for the so called "English Club Model", an 88 with built in power amp and preamp.

Preamp is totally noisy and I'm trying to give it some care.

Anyone knowing a source for the schematics?

Seems to be a rare or little known device, since it is UK made. Maybe anyone from UK in this list might know the company who made it:

DMI (UK) LTD  FARADAY GROUP OF COMPANIES 2x50 WATT

is imprinted on the PCB bottom face.

I couldn't find much about a company named DMI and having to do with electronics in the net.

I was already able to get rid of the noise by resoldering every solder spot on the power amplifier board finding two blatant cold solder joints.

Possibly I could make the amp working again without having a circuit diagram. But it is always annoying to "work in the dark" and I'll probably try to reverse engineer the schematics unless someone comes up with one here.

DMI Most likely represents Dallas Musical Instruments (formerly Dallas Arbiter) in the UK. They also made Sound City guitar amps and these photos do look very simillar to guitar amps around that time.

Thanks for the information. I remember "Sound City" from the sixties :). Would be great if I can find someone from the engineering staff today who can offer circuit diagrams. Otherwise I'm left to reengineer them (which I'm half through anyway) :)
