Paul,Thanks, just what I was looking for .
Yes, I actually do take the turns ratio and DCR of primary and secondary into account. I thought it was something simple - like Peak to Peak vs RMS, but you, and one other helpful person, nicely confirmed it for me.
Like so :
" The 550 is peak to peak. 550/2 = 275 peak. RMS (what you meter reads) is peak times .707275 X .707 = 194mv ac rms so the PSUD was not that far off.
You see, all this stuff is really just a matter of math and science. :-)"
Well, I am breaking-in this 45 DC amp on Willie Nelson and Johnnie Cash tonight. Need to tube - test all my RCA and Telefunken smooth plate 12AX7s, and get the best in there. Am pleased with the presentation so far, the 45 is pristine in a good DC amp. Only three hours on it, heck - the solder joints aren't even settled-in !!
