I had one of these amps from 1962 - 1966. I used it with an EMI EPU100 integrated arm and cartridge ( mm ) A rare pickup. Goodmans AXIOM 400 type speakers. The whole system sounded pretty good back in the day. I recall the 305 preamp had poxy individual gain setting pots in the low level signal path and could be very noisy. Otherwise no problems.
