AU-X1

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?

Since 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.

Those ones are a bit of a mystery though the only markings on them are on the bottom and it reads E B
 
I put these in for now but I noticed the mica insulators are touching each other should I trim them so they are not touching?20160617_154049.jpg
 
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?

22 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.

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 right
 
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?

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.
 
So far on these boards all I've done is change electrolytic's black flags 20160609_134739.jpg
,trimmers and some out of spec resistors 20160609_134643.jpg
