Default Re: PEN3520 Amplifier project

Hi Graham, looks a bit like an early Quad amplifier before the Quad ii. I think it was called the QAP12 I think.It was usually paired with an long/medium wave tuner. I owned one many years ago but your is a bit different, i.e mine didnt have the the telephone keyswitch , dropper resistor or the dry battery. the knobs look correct though. A friend still owns the amp/tuner so I may be able to get a picture.
