Leaks not getting on.
Hello, I have recently restored the Leak Stereo 20 power amplifier & have almost finished work on its control unit, the Leak Point One Stereo Preamp.
When I connect my CD player to the amp, it plays perfectly albeit with the inbuilt volume control @ minimum level of course. When I connect the CD player to the control unit & monitor the o/p with headphones, it sounds clean.
When I connect the control unit to the amp, there's quite a bit of hum:( & I have rewired the eight-pin connector using shielded wire for the audio conductors & the earths are securely connected too. Any ideas please?
