Low filament Voltages

[Johnny1234]

How I am just finishing the final touches the Dave P mix buss compressor. With my lights hooked up my filament voltages are about 10% low. Don't want to use led lamps as this piece is so cool. How much harm if any is this?
Many Thanks John

Hi,

Iow you might have to try by yourself to see if it makes a difference. That said 10% is not a lot and some brands just run their tubes at 5,7v in commercial offer and nobody ever complained on the longer lifespan of tubes.

I don't know the tubes Dave used so can't comment more on them. Maybe there will be a difference on the varimu tube of the circuit idk? But you should not destroy anything in a test.
