Arran,
I just received my manuals and diagrams in the mail yesterday. These will help a lot. You said Ron had a lot of information posted on the model 95 but I can't seem to find it. The links you provided were only for 2 schematics. Maybe I misunderstood. Is there more? I looked in the tech section like you said and see things about every model except the 95. I'm sure it's somewhere. I must be blind!
Even though there are no electrolytic caps, I guess you guys still recommend changing them all? Resistors also, even if they test ok? Is the thinking here that a failure of one of these 85 year old devices could cause a fire or damage to more expensive parts? I'm trying to figure out how to open the condenser box, now that I know what's inside. I can only lift the cover about 1/4". Don't want to force anything. Could something have burned inside and stuck to the lid? Found 2 bad tubes and will be picking up replacements plus a spare of each type this weekend. Amazing what people save!
Thanks,
Sal
