Default Re: Sony TA-1010 noisy phono circuit

I decided to replace all the transistors on the power amp board, as these are known noisy transistors.

I had a load of spares anyway, so whilst it was open i thought i might as well.

Luckily the noise on the left channel has now gone, So these must have been the culprit.
