I'm wondering about the -18, -2, and -100 v sources, as it looks like they are providing bias for all
the little tubies that are also using the 135V & other sources... Higher G1 voltages will
mean all the tubies conduct just a little bit more for each one.... and you know
what that means.... More Ampies being used.... and if the 3 tubies you
provided G1 voltages for, they are each a little higher..... More
ampies means B+'s all go down..... Good suggestion about
monitoring the 135V as the set warms up, I suspect it will
go down as the set gets going, no surprise there...

Hello there...from my read of the schematic the volts on these should be:
6SK7 #4 -4.3V #6 129V #8 165V
6SH7 #4 -5.2V #6 135V #8 134V
6SN7a #1 I don't know! #2 88V
As for resistors, 228, 153, 159, 157, 158, 160 all test dead on. I replaced 154 and 155 because they were a smidge high.
