Gotcha. Thank you. Congrats on the new building btw. That view from the workbench looks awesome.Yes. We only ship long pins with the CA-0252. They will be .2" (5mm) taller than the other opamp pins that are in the gar kits etc.

Placement does not matter on the 2N5087s.Dumb question - I'm building up four of these, and I noticed that the 2N5087's have three colored stripes on the backs of them, almost like they've been graded. The markings range from what I interpret to mean 415 to 422. I'm guessing this is gain? Does placement matter on these?
That should be fine.Hi Jeff!
If I've messed up one of the 2N 5087 transistors, is it okay to replace it with another (not CAPI provided) 2N5087 TO-92 PNP (iPartsLike WXKNewicG-10654) general purpose transistor? Or they don't match that way?
Sorry for the noob question.
Thanks

Thanks for the reply, Jeff!That should be fine.
No need to clip them. They have the same clearance as the modern 2520. That way they can be used in all of the same modules.Hello, I just finished one and realized, that the terminal pins are ridiculously long, is this correct like this:
I can't push them down any more. Should I clip them?
Thanks and greetings from Vienna, Austria!
Thanks for the fast reply!Jeff is using the longer pins now. He originally started using them for his potted opamps, but ships them with all of them now.
Thank you! I was concerned because all the older builds look like the opamp is nearer to the board. Gotcha thanks!No need to clip them. They have the same clearance as the modern 2520. That way they can be used in all of the same modules.

The original 2520 had no internal circuit connection to ground. Many of the more modern amps have added onboard 0.1µF PSU decoupling caps which of course go to ground. Since the original amp did not have these, I did not use them either. Hence, why put in a pin that literally connects to nothingForgive my ignorance, just trying to cover all bases...is there a reason why the CA-0252 only has 5 pins? The pcb's i've seen seem to have slots for 6 sockets. Again, sorry if i'm missing something here really basic. I know it's not the same DOA as the Gar2520.
Much thanks!
