Hi Jason - Are your candohm resistors open? Just curious since it sounds like you've done the recap. I generally leave them if they're working.

I used 25W resistors on my 37-2670 (very similar set). They still get pretty warm so be sure to mount them to the chassis - or in my case I used an aluminum sheet to mount them so that I didn't have to drill additional holes in the chassis. I use lithium grease under them to ensure decent heat conduction.
