Pics in post #1291. Schematic? Maybe at some later time.Who cares about grounding...I want to see more zd25 pics and a schematic!
Wow, thanks a lot Mr. Pass I greatly appreciate you took those tests, it's really generous from you!Nevertheless, because it is important to you, this morning I took an F7
and put it on the bench and measured the following with my trusty AP.
I didn't want to bother you with this issue just beeing curious how such a GND layout doesn't cause any major hum.
It's intresting what the simulated model was missing if the real life measurements are so different.
Thanks anyway!
ZM the made me do it.
Hah! That's wonderful.
Thank you Papa for the measurements.
(Will also remember that line the next time I have to explain why another box of parts shows up... )

Can't wait until Mr. Pass publish F7 schematics
You should be excited, if the schematic comes out. These are great amps! I have two simulated F7s doing highs and mids duty, plus a F5T v2 on the woofers. Got some great reviews from my audio group yesterday. They seemed to really like the sound. They liked my DIY speakers, but I gave all the credit to the power amps and B4s!

Wow, what an arsenal of Pass amps!

You don't know the half of it!
The list is long and distinguish!
Hey Vince,
Tri-amping is a great way to use amps you've built.
Any update to the "family photo"?

Just MoFo monos and another BA3-Pre with switchable gain. 6w vFet amp went to another family. 25w SE Schade feedback amp on the bench next.
Oh, and mosfets F6 needs surgery, but it will be just fine!

It works fine for me.
For me too
Strange. This is what I see.
What is your web navigator software ?
Try some different one , maybe another do work better.
Book with many interesting chapters. Good luck
