Default Re: Vidor CN429 'Lady Margaret' fell silent

Ah, but if the switch had failed, then the circuit voltages would be wrong (see first post).

Can squinancy confirm where he/she measured the voltages? LT measured betwen pins 1 & 7 of any valve, and HT present on the primary tags of the output transformer, would absolve the switch.

Me, I'm thinking the output transformer has died, or the output valve filament. However, the DL96 has two filament sections connected in parallel so both of these would have to fail to kill things completely. Could be the loudspeaker, but that's less likely still.
