Most recent update. I got the package and replaced the transistors. Well . . .
I had the MJE350s backward. Completely my fault. But... When I plugged it in the HLMP 6000 that I replaced (my stock, not a Bottlehead replacement part) was burned out. I surmised that they don't have a high enough current or forward voltage rating. So I ordered from Digi-Key.
Those came today, I have a lifetime supply.
A couple of solder joints and everything is within the +/- 15% except terminal 2 (187.2V). With tube variances that should be close enough.

I'm plugging in headsets and going to pack this one off to the owner. I feel guilty about how long this took me.
