Re: HMV 1120 Very Strange Goings On
With the noise present switch to gram and see if the noise stops. If it does you know the noise is coming from V1 or V2 stage. If it doesn't then try grounding the grid1 of V4 the output valve. If the noise doesn't stop then the fault lies in the V4 stage. If it does stop then the noise is coming from V3. Cheers, Jerry
