Hi everyone-
I was just wondering if anyone here might have specs for the MkII C/C+ power transformer, 100-162318. I have searched around the forum, but didn't find what I needed.
I have looked at Boogiebabies excellent thread "MkIIC+ Guide for Dummies" thread, which indicates my DRG IIC (later modded to +) came with the early 100 transformer.
The voltage associated with the early 100 is shown at 448V, but I take that to be the "A" node B+ voltage rather than the actual high tension secondary AC voltage off the PT... am I correct in this understanding?
The HT secondaries on my PT measure at 340v AC on either side against the center tap.
The low voltage secondary tap measured at 60v AC.
Does that look about right for my transformer? Wall voltage here is 122-127v AC as I am about a block away from the electrical switch yard.
Thanks for any help.

P.S. For the record, DC voltages were as follows:
A=469v
B=469v
C=402v
D=360v (C --> D dropping resistor is 5.6k)
E= neg 59v
F= neg 49v
Pin 3 at power tube plates = 437v

60W PT - 00-162310 - 448V
60W Export - PT: X62-162318 - 448V
Early 100 - 100-162318 - 448V
Simul/60-100 Power - 105-162318 -483V+
- X101-162318 – Export - 448-460V
180W - 0180322 Coliseum - 500V+
Some early IIC+’s may have leftover 100 power transformers.
