I'm having trouble with my Marantz 2265 with popping and spiking DC offset. Idle current holds rock steady until I hook up a speaker to outputs. Then idle current starts to spike and I can hear it in the speaker as hiss or pop. Noise is apparent in both channels. This all began after a total re-cap of the P800 and P700 boards, main filter caps and new speaker protection relay. To try and isolate the problem area, I plugged pre-out into another amp and listened for popping. No pop! So I'm figuring the problem is in the P800 power supply board? I replaced all the small transistors on the power supply board. No change. Guess I could replace the larger transistors on the power supply but I'm just back to shooting in the dark. Thank-you in advance for any help you can offer.
