RE: SUN SV 2A3 stereo SE amp .... MEASUREMENTS

Posted by drlowmu on April 1, 2015 at 18:51:24:
CB,

(1) "That might be too technical for Jeff."

YOU asked for it !!!!!

FYI, I mastered graphic load line analysis in 1982, taught by the late Bob Goodman of Texas. .............Were you even born then ??

(2) You don't like "competition" I can see. That is OK. I understand.

(3) Your own graph is laughable - INCORRECT in two or three ways :

(a) You don't know the STARTING B+ level, because you don't KNOW what FILTER I am using and its effect upon B+ ( VDC level ) on the 2A3's plate.

(b) Nor do you know how much the power transformer will unload, raising B+, with my unknown but lower current load.

(c) You don't know what op point I decided to use, as a best compromise in this amplifier.

(d) The 2A3 quiescent point you have denoted is well above 50 mA. and is of course, totally WRONG.

If you were intelligent, you would NOT have drawn that and then quoted textbook baloney as to distortion and swing, that even a well trained parrot could recite.

Well, maybe you can do better the next time you RUSH to attempt to discredit me C.B. You will have to THINK before you post though.

What does the "P" after your moniker stand for...Industry Professional. OMG. Save us amateur DIYers !!

Until someone offers to make a few measurements on a SV 2A3, I am done with this thread totally - and outta here.

Bye all !!! Have fun.

Jeff Medwin
