Some Pictures of the X-101C Working
Dave;
Thanks for those suggestions on equalizing the drive through the output tubes. The adjustments are probably not far off now. I will pull out my 100W load resistors and signal generator plus the meter and make the adjustments you described. It is nice to know the best way to make this adjustment for minimum distortion.
I do have a suitable generator that can produce the 1kHz signal (and any other from below 10Hz to 1mHz). I just completed a final check by injecting a 1kHz signal into one channel while looking for any crosstalk into the other channel. This also served to check the full operation of the mode switch and all worked flawlessly.
Here are some pictures of the amp working.
Thanks again to you and to all the great people here on this forum! I could not have accomplished the fine results without all the help.
