Default Re: Homebrew Record Player. BSR UA6 deck and RS Components. Stereo Amplifier.

That valve amp smoothing choke looks like a misguided addition. It is not needed for a transistor/IC amplifier.
The measured voltages show that the primary of the mains transformer is right but the secondary are in parallel. Once the transformer is right and the choke is out of the way the amplifier can be got going. You should get about 15 to 18 volts.
The deck can be put to one side until the amp is working.
There is also a transformer of unknown heritage between the pickup and amplifier most likely added because the pickup was duff.
