Default Re: WD Phono 3 - DC on Output?

Hi Moley, there is no difference now, between the 3 and the 3S, they are the same board, it is just the first stage coupling capacitors, Phono 3 uses .1uF 250 volt in C1 and 2 position, 3S uses .033uF, 250 volt in C1 to 6. C13 to 16 are 10uF 450 volt, your 400 volt would still be well inside the working tolerance, and yes R35 for you should be 10000 ohms. If you have been running it with 1000k, or nothing, you may have too much voltage all round, please check. BOB
