Default Re: HMV Mono Record Player Problem

I did a bit of digging and found that the likely model number is 2004

The service data is available from this site: http://www.service-data.com/product.php/2785/3750

The third valve is another UCL83 it being a push pull output stage, with one half of the UCL's acting as first amplifier and second half as the phase splitter.

You must change C8, C10 and C11, C7, C14 & C15 are all in one can, and will need reforming or replacing.

The missing control is the bass control and is a 1M lin potentiometer.

This would have been quite a classy record player in its day, the push pull output stage would have given it more power than normally available, the separate bass and treble controls would have been somewhat luxurious in its day.

Please please please, do not discard the amplifier, if you feel that restoring is beyond your capability and you cant find anyone to restore it for you then offer it to someone who can in the sets and parts wanted section.

This player is far too good for the skip.
