It’s already paid up.Boy, I don't want to see your bill... whoa..
Unusual design to have 3 rows of transistors per heatsink.Fun statistic I observed while there. Each amp has 30 pair of 120w (or 100w) 10a transistors. (I suppose that’s a PNP-NPN arrangement) A can do machine right there. Plenty of transformer and cap supply to back them up too.
I don’t think they would have done this were it not for the fan cooling. Each heatsink has two 2 speed fans on it.Unusual design to have 3 rows of transistors per heatsink.
There is hope, finding a tech with enough time and deep enough pockets and the right test equipment was difficult. The deep pockets part is on account of the sheer amount of time spent on this, but enough bench and employees to keep going and not have this project occupy all of their time. There’s like 100 hours in this, and I am not being charged for anywhere near all of those hours.This thread gives me hope that one day the NRG's will be fixed and that i'm not alone in the struggle.

We are very close to the finish line. Between me and Dazaa with the NRG’s, it’s gonna be a close call as to who’s first.
A few pics from a week or so ago of the one here.

Sometimes yes, but hard to find parts on really damaged older stuff can be cause for major delays. I’m still willing to think you could win.You'll definitely win, my tech is so slow and unreliable i'm sure the Nrgs could have been working years ago if someone else had them.
2SA2705Y do not exist
That makes them particularly difficult to locate.
