80 Jr Troubleshooting- B+ measurements
#14

LOL morzh! Nothing like a self-inflicted problem, but it was good for me to sort through tracking it down.  This is only the second set I've worked on but after viewing one of Bob Andersen's videos I decided to go ahead and take it "almost" completely apart to clean it up.  It was pretty rusty so I thought this would be a good set to do some learning on. I know there has been debate on painting chassis but decided to at least do the top since that's where the rust was.  Left the underside alone.  Some pics in various stages; the last with my attempts at molding dogbone resistors (the 3 in the center)...I think that will take more practice Icon_biggrin

I also learned in this process that the bakelite cap blocks are not always wired as you would expect them to be from the Bakelite Data Sheet, so you need to double check them.  

Now back to tracking down why my B+ is low
