Hello there, I recently inherited a 1000A tube receiver, I have replaced all the Elna and Suzuki oil caps, and have extensively cleaned all the controls. The recap / Deoxit restored proper function to a lot of the tone controls, inputs, balance, and other functions. However I have a weak right channel, it sounds a bit staticy and seems to be about 20% sound strength, compared to the left channel. I have not messed with any tubes yet, any info on tubes and possibly what certain tubes on the unit actually do would be greatly appreciated. I have never worked with tubes, I mainly have owned 70s Marantz 2xxx 4xxx units. All functions and inputs seem to be working, however my right channel is consistently weak. The stereo reverse function seems to work, I feel like that may be telling us the sound is processing correctly, just that the receiver can't deliver proper sound output to whatever channel is assigned to the right speaker.
