RE: PING to Audio Note Kit One owners




OK Peter,
this are the test results, with a direct connexion from pin3 to ground on each 300B (marked with green lines on the pincture), de-solder (+) terminal of the cathode capacitors on 300B. Only rectifier and output tubes were inserted:
No problem with the fuse
Anode (Pin 1) 300B (to chassis ground), left and right: 212 VDC
Cathode (pin3) 300B (to chassis ground): no voltage
5U4GB tube went very hot, increasing temperature and color while I'm doing the voltage test.
Before I continue with the next step, what do you think?
Best regards,
Beto
