Another thing I found on the f-2775 is on one of them they had 91pf black flags and on the other board they had 47pf black flags in the same spots.
Possibly production run changes? to get rid of instability.

Currently 5 pairs availableWell, that's fine but only one pair, we need 3.... BTW: the seller's reputation is beyond reproach - AK's own 'Kale'.
Which auction site am I looking for?Currently 5 pairs available - and yes expensive

I had some time last night so I pulled f-2775 out and checked the out puts and all three of the 2SC2493N's are shorted.I do have a bunch of MJ21194G -93G's available but was wondering about what the best replacement's would be?
Those ones are a bit of a mystery though the only markings on them are on the bottom and it reads E BSince you have two X1's, why not just source the output transistors from the other X1?
Just get the first one up and running.
If you are sourcing from this one

...your Peak Atlas should be able to sort out which OT is which.
Thanks for the tip I just bought all 5 pairsfifth letter of the alphabet - than add "bay"

Wow! - you don't mess about -Willy6 said:Thanks for the tip I just bought all 5 pairs
Actually he had more then five so I bought six pairsWow! - you don't mess about -![]()
Ron question on the G5V-2 relays.Is the 22 gauge wire the only thing holding them down to the board? and I have lots of 22 gauge solid copper wire is that ok?Mica touching is harmless.
Transformer looks spiffy.![]()

So basically you just made the relay pins longer with insulated wire so you could reach the holes that are set a little further back right22 gauge solid copper wire is actually what I used. It can be harder to work with but approximates the original pin sizes and rigidity very well.
Regular wire is ok too and easier to work with in a lot of ways.
Yes I'll post pics as soon as i get the time to do it .relays arrived yesterday but I still have 3 more 14 hour night shifts first day off is Thursday but I'll probably sleep the first half of the day then get started on it.Yes. It's really easy to do once you have the wires soldered onto the relay legs.
Just thread them through to the correct holes in the PC board.
Solid copper is trickier than regular wire. I lost several relays before I perfected my method of crimping the solid wire to the respective relay leg. I can buy them in town here easily, so it was no big loss to lose a few.
I guess my point here is the relay legs are really breakable. Solid wire can add a lot stress to the relay legs, where regular wire since it has more give is less prone to rip a relay leg off.
Any chance for a pic of your relay work when done? Perhaps a side by side / before and after shot?
