Ken,
The measured (AVO 8) off-load AC voltages for Anode and Screen voltage settings on the 45c are as follows:
Code:
ANODE
Setting Measured
60 65
100 106
200 215
250 272
SCREEN
Setting Measured
60 64
100 108
200 216
Looking at the diagrams, when Taylors changed from selenium/metal oxide to germanium rectifiers they appear to have made no other significant changes.
