Sorry to hog the forum, I'm a bit of a noob, and this is SO helpful! Right, so first thing is to get rid of the Sovtek 5Y3, so I've ordered a NOS Jan Philips. But from what I've read this is only going to reduce the voltage by 20-40v, so I'll still have at least 377v, maybe even 397v? My understanding is that the ideal B+ voltage for the 5E3 is in the region of 350v - 360v, is this right? Replacing the PT is not really an option, so how would I go about reducing the voltage to this? Thanks for the help!
