Re: HP200CD oscillator


 

OK, I am still working away on this restoration. I have the new rectiier tube in place and now wanted to start probing some voltages.

Can someone confirm that the voltages on the schematic are DC voltages ? At the base of R27/R28 I see about 290V DC and not 215V as per the schematic ? I Also do not see a 30V drop across L6 (245V to 215V), in fact I see about a 6V increase. Also the resistance across L6 measures 226 Ohms which seems ok ??
