I have to pop the top to check the bias. What do you want to see? happy to supply pictures.
The chassis is custom. Built around the big heatsink usa heatsinks. Black stuff from Front Panel Express.
Let me know what you need.

Hello rmauror,
I built the last few poweramps with those aluminum frames. Makes them super
strong. And easier to repair. Put the lids/panels off - good access to the electronics.
A few weeks ago I made a little stability test (check pics) for your fun....

A Plea For Help... Bad Dad Support Group
Dirk, I have chassis envy...
Won't someone do something to help these lonely, displaced, adorable projects? When they were young, they each had their own chassis. Even hand-me-downs from their older siblings were okay with them. They understood we were a family of limited means.
Then as they got older, they were kicked out. I bring them in and give them warmth and shelter in a nice chassis periodically. They can tell I'm judging them and comparing them to others. I tell them I don't play favorites, but they know. They know....
I look at others' projects and wonder if they're "better" than mine...
In the evenings, while I'm playing with the youngest, I can hear the pleas and hopeful cries. My Aleph J whispered, "Please, sir... just a bit of warmth in a nice chassis... if only for a month... I don't even need dual mono or balanced inputs, but it would be lovely... "
My M2x has eldest-child syndrome, I think. I was too hard on him. I just didn't know how to make the right adjustments early on, and there may have been an over-voltage. I did everything I could, but there's still scarring. I'm ashamed to change IPSs all the time... as if the original configuration wasn't just perfect. I heard a whisper, "Why do the younger ones get all the new fancy parts and better treatment? I've never seen you burn any of them with an iron" It's heartbreaking.
They all bring me such joy. I picture each of them in their own beautiful custom chassis emblazoned proudly with their name.
If only my wife weren't so heartless.
I heard her say just the other day to a friend, "If he wants any more.. some of them are going to have to live in the garage". The garage!!!! Who would do such a thing?!

My BA-3 amps ( I built 2) - the first pretty normal on +-28V - rails
the second one is running on +-34,5V - rails = hot rod. JFets living close to the edge...

yo Bubba, why don't ya cascode them?
easy peasy work, if needed you can do it even without drilling the pcb and without exacto knife
Itsallinmyhead,
Looks like the beginning of a decent collection
My count is currently: B1 Korg pre, two ACA (original TA mods), two ACA-220 (Hafler chassis), M2x, Aleph J, F6. All completed with full chassis.
On deck: Penultimate Zen v4, two MoFo monoblocks, Singing Bush, SIT-3X, SissySIT.
