I’m currently working on a V200 amplifier and can’t figure out where the current draw is coming from. I’ve isolated it to the 6.3 heater circuit but can’t find any issue with it. The only problem is the humidity adjustment is missing the wire wound section so it’s basically not doing anything. I put 2 resistors in place as a replacement but when I fire up the amp my amp meter starts rising and I shut it down between 2 and 3 amps. Usually when texting one of these amplifiers it slowly rises to about 1.5 amps and holds steady there. What am I missing here?
Start by unplugging all the tubes and see what happens. Then plug half of them in and see if the current is OK...then 1/2 of the remaining tubes...splitting problems in half speeds up the discovery process I find.
