Hey Gang of Brains...
I've got a 9100B that I've recapped the power supply for, and it sounds a lot better. But, here's the odd thing. It's set up for stereo, I feed it stereo and it comes out mono. I've checked the L+R and L-R jumpers throughout, the mono jumpers on card 1 and all other points. On the input buffer, I can switch between L or R channels and mute one or the other and the input follows. The output LP filter position on the meter tracks as well. But, when I listen to the "stereo" output, all it does is drop 6dB when I mute a channel on the input but stays across both channels.
I've gone through it twice to make sure everything was in the right position switch wise, and it doesn't make any sense. Could someone have tied the two outputs together inside as a modification to take it back to "mono"??
It isn't really that important that it does stereo as it will be a backup to the 9200 V3, but I'm a stickler for if it's supposed to do something it should do it properly and well.
Any ideas?
