Hi diyers,
I have a dared vp-845 6SN7 model which is the later version than the older 6L6 model
The amp recently stopped working. Upon inspection the tubes are lighting up but the plate voltage and bias for the driver and preamp tubes is missing. Also the PSU readings are showing a lower than expected reading normally one expects to drive an 845
I’ve been looking all over for the schematics for this amp including the power supply section.
If any of you have this to share I would be most grateful

No audio at all from any of the inputs. As I said there is no plate voltage or bias in the driver and preamp tubes.
I would check the mains fuse and then step by step toward the amp until you find where you lost the supply voltage.

Yes but the readings I’m getting from power supply indicate a very low voltage compared to what is usually known to drive 845. Is it by design or is it a problem hence like to see power supply section schematic
600V what? Look, you ask for help but are not willing to give the info we need to advise you.
I'm out.
Good luck.

Wow I see patience is not your forte. It was quite late when I was responding and hit send too quickly. 600V DC at the plate voltage of the 845. But most 845 specs say I should be getting close to 1k ?
Secondary is AC 240V
