Roger,
Thank you for your generous advice. your response took a lot of thorough effort. I am still at a loss to figure out my issues. When I put an alligator to the volume control and the 42 plate I can hear feed back in the speaker but I cannot inject an audio output across the speaker coil. I must be doing something wrong. all the tubes light up and I checked them using this site http://tubedata.tigahost.com/tubedata/sheets5.html I also did #3 but no tone. I can use my Eico 324 and tune to a radio frequency on another radio so that works. I replaced the capacitors and resistors but I noticed my Model 60B is not the same as Bob Andersen's per his youtube series. I bought a cheap analog multimeter today and tried to follow Ron's step by step (from this site) but again, no tracking on the speaker. Yet the speaker gives audio feedback etc. I'd like to step it backwards but everything seems to point to the audio to speaker and the lack of response using the volume control. I'm in over my head on this. Thank you again. Rich
