Default Re: Help - Phono 3 Heater voltage Measurements

Hi Moley and all I would check your PSU again, is C5 the correct way round, is R2 150k, is R3 22K and is R5 100 ohms. Your voltages are a tad high too. It would be advisable to double check everything. What is the HT value in the Phono at the juction of R29/R31. Do also make sure you have a good connection to the chassis. BOB
