Need Yamaha transformer CX-1000 preamp

What's the size and pin spacing/function?

How abut a wall wart?

A lot of surround receivers have a 12V standby supply derived from a small transformer on the board. If you look at the size of the one you need, you might find something very close in an old surround receiver. NAD, Arcam certainly used them, and I'm sure others as well.

You might also want to look at all of the pins on the old one, as you might have an open thermal fuse. On some transformers it might be possible to replace it. Sometimes it will take unwrapping the transformer tape to find it. I would NOT suggest bypassing a thermal fuse as a long term solution.

nsformer and it works as it should, but it's too big to mount in the confin ed area. The original transformer is a through the hole PC mount.

sell, or do they know of a close enough sub to fit the board for this model . I don't mind relocating foils or redrilling if I have to but customer pre fers to keep it authentic if at all possible. Thanks.

Thanks for the advice fellas. For posterity, here's a solution by substitu tion, although the sub may be just as hard to find in the near future. By w asting far too much time, I discovered that the Sony 1-448-852-11 transform er is the same as the Yamaha XA754001. Same size, footprint, and even the same plastic foot snaps. Perfect fit with no mods required. All is well.
