Thanks for all replies so far. I've replaced the smoothing caps and the tone control cap and the amp now runs well. I did order some 1N4007s and 150R 5W resistors, but it seems that the original metal rectifier works fine, so is it worth replacing it just for the sake of it? Also good news, all 3 cartridges work fine with a good clean output. One mechanical problem I have is that the motor is running slow. Definitely the motor - I've cleaned the jockey wheel, set the correct height, cleaned turntable inside rim, cleaned and re-greased the central ball race, etc, and have removed the cam so the auto-mechanism is not in play; turntable spins freely when disengaged, so I think dismantling the motor and cleaning inside it may be the next step. Incidentally, as I previously mentioned, I actually have 3 decks and all of them run with varying degrees of "slowness" so I'm concluding that years of inactivity have caused this...
