Here's an update on my 41-250--I installed the new Hammond transformer. I'm now getting sound from the speaker, but it's an oscillating sound from one of the output (41) tubes--the one that is glowing hotter than the other. Starting at the power supply I've run value tests and everything checks out okay until I get to the other side of the field coil. I'm getting a somewhat high 309v DC out of the rectifier (84), which then goes directly to the field coil where it comes out at 265v, but should be 180v according to the schematic. Of course this 265v gets passed through the new output transformer and to both output tubes. I checked the resistance of the field coil--1100 ohms dead on. I've checked many times all of the cap connections and everything is as it should be. Could the excessive voltage be a caused by a bad rectifier?
