I recently picked up a Marsh DR used. I installed new JJ's and using my bias rite set the bias to 25mA at around 470 Volts. I know the DR has always run hot and that JJ's can take it but I was still surprised to see a newer clone running the plate voltage that high. Anyone else have a similar situation in a newer AB763 clone? Should I even worry at all or just play it? thanks!
