Found it! 1TR15. Replaced it and everything works fine. Waveforms are still wonky though. ???

Going to replace the rest of the transistors and also the caps tomorrow, do some final adjustments and send it home.

Thanks again

Craig,

Im only a bronze member at the moment so I cant view the info you mention. I dont work on much B&O stuff and haven’t had enough trouble in the past to post for help.

I do have a tester and some BC547 transistors that are coming up as a close match. May just replace them one at a time and test as I go. The only one Im missing is TR18.

As far as testing TR17, that is a typo on my end

Need to step away for a couple days while I still have some hair!

Again, thank you

Yes the tonearm is over the spinning platter.

I soldered jumper wires to the points shown on the schematic in order to get the scope readings

Yes the pot is the one for transparent discs. The arm will drop in the correct spot with or without a disc on the platter with the pot at one end of travel. If I turn the pot the other way, the arm will not drop at all, but will run to center then back to stop.

Going through the flow chart, I get to step 4 ok but am having some trouble understanding the points to check as everything is abbreviated.

Thanks again
