::::::EDIT:::::::::::::::
I ONLY tested the offset on these in a PULTEC, SS AMP CIRCUIT!
The conclusion of this thread is that the "Circuit design" could be the cause & NOT the Amps themselves.
:::::::::::::::::::::::::::::
DC offset is about -144mv :shock:
- FABIO's 2520's - from the last batch.
Doesn't this sound a little high???
Has anyone else measured theirs?
I have 12 of these - 8 are in my 8 channel API 312 (which is 99% complete)
...I planed on building it stock - NO Output CAP
But now I'm concerned.
I should mention that I'm using Fabio's & Cinemag's STEEL CORE output TX's.
I know what some of you are going to say... just use a CAP... I know this but REALLY would rather not. I prefer the more open sound I'm getting without the caps BUT I don't want to damage the AMP or TX.
I spent hours listening to MANY different Caps last night (In my Dual Pultec that uses the 2520 for the output amps) they ALL change the sound but the Panasonic FC seem to be the closest to no cap, with the Nichicon PW not too far behind. (I also tested MUSE & other high end caps.)
