Well, it's officially running.. Kinda

I figured since im waiting for some parts to come in for my 67 SC600 I would take a stab at the Heathkit..

This is another set I picked up from KX250rider. 25XP22 CRT needs desperate cataract removal attention, but did respond well to an 8v cook overnight.
I was told that the flyback was arcing and was not used since then.

Well I opened the cage and found the 3A3 and socket assembly hanging with no mounting hardware just resting on top of the flyback. Amongst the mass hysteria in the cage I found the focus lead broken off the lug. I resoldered it and a mess of other wires (anode and cap to 6BK4) with bad connections. I resoldered them too and the 3A3 socket is missing the back cap so I dummied something up with a spray paint cap and some electrical tape for now..

Im going to test it tonight and post my results..

Oh haha no that screwdriver was not used in this. Well I got a raster and a blurry color picture. Looks like I'm on the right track.

As you can see this set probavbly needs recapping. I brought it up with the HOT removed on a variac. But somethings going on..

I have a condenser checker and I am going to check filters for leakage

Yep, I'd be pretty happy with that at this stage!

That's great news! I'm pleased that it wasn't a failed FBT. That set may not need recapping, as the original owner was using it up til maybe 4 years ago, if I recall. He was also the type who probably spend hours & days on the alignment, getting it "perfect". He's a ham operator, and a retired engineer.
