Turns out it was bad soldering between the PVI cells and the board
I re-soldered one channel after tinning the cell and it worked !
Unfortunately I pulled the pad off one of the cells on the other board 🙁
So I ordered a couple more, now I have to wait...

I'm moving it to my main rig this morning paired with either a Pass B1 Korg or a Dodd tube Buffer (I can't decide which to use 🙂 )
It will be driving the upper end of my Hawthorne Audio Duet open baffle speakers

Here's a build of this amplifier I did for a customer. Since I don't know if he wants to get named on the forum, I won't write his alias, but he's more than welcome to reply to my post.
Please see hyperlink for the build thread. It is a mono-block arrangement.

Hi , I'm late to the GB, I've checked all around for the 7293v chips and none are available ... does anyone have any of the 7293v Chips ???
- I need 4 , right now it looks like the earliest possibility is October or November..... Seems so far away --- thanks for any help .

If you order on eBay, order kits that have two in parallel because those can't be faked in the same way.
I prefer trusted suppliers but what are you going to do... wait a few months! The time was December so it's been getting shorter.

So how does it sound pinocchio?
Did you get to listen to this build using your reference speakers? How does it compare to other amps you've built?
(ps For context pinocchio built my EC7293 last year but I didn't ask to put in speaker protection circuits because destroyer_OS didn't feel they were needed. This meant pinocchio didn't feel safe listening to the build through his reference speakers.)
