25K7000 with really awful solder joints. After correcting the usual suspects, started poking around, since I noted that the fuse was blown.
HOT replaced. C38 replaced. And, since C38 was blown, I started checking other things, as was detailed in my other thread from a couple of years ago regarding a K7000 with a blown C38.
I'd desoldered D13 and D14 (and forgot) and I fired it up with the lightbulb trick to see what it would do (now that I'd replaced a bunch of stuff) and it fired up, though with a lot of ripple (and a really small picture, due to having a B+ of 100VDC).
Back to the bench, soldered D13 and D14 back in, replaced the lightbulb fuse with an actual fuse, fire it back up...and nada. B+ of 145VDC.
More as I find it.
