creative input tranformers (api 312 style)

So,

I ordered some cinemag tranformers for some 312's I'm working on, come to find the pinout is different than the board I have ( you think I'd learn after a few projects). After askin some questions here, here's the solution:

That's a pretty sweet little adapter. Did you etch the board yourself?

Nice solution... better than jumper wires going all over the place.

thanks,

I'm pretty happy with how they turned out. Saved it from lookin like a lot of spaghetti.

Yea cool! Nice solution!

I'll need to do that to fit CMMI10B in a CM75101 spot... :S
The 10B is a little larger with more spacing between pins.

cheers!

I made adapter boards like that for a couple of different Lundahls. Trouble is, when I mount my main PC board on 1/4" stand-offs, the adapters cause the transformers to bump the top cover of a 1U rack chassis. I don't want to cut the pins on my transformers and that eats more space between the adapter board and the main PCB. It's a tight fit, but it works for DIY.
