Hello
have a bc610E driving me nuts! Got this unit up and running after re-capping Osc/buffer/IPA section,
Dead and blowing fuses when acquired, Solved!
Problem: when exciter voltage is engaged, oscillator comes right on regardless of CW key being up in the 614 unit,
Seems cathode of 6v6 is hard grounded through exciter plate switch SW3 as is in the print, I cannot get the key to interrupt oscillator
unless I remove the lead from pin 3 of TS1, Seems to me the key circuit should be in series with the SW3 but it is wired in parallel
so as soon as the switch is engaged, the key/614 and SO5 is bypassed.
Has anyone run into this?? this is a 1944 unit, Any help/wisdom will be greatly appreciated
Thanks in advance
Dick
