Zenith Console combo

yea, got it back in the cabinet, works fine now, but for a noisy idler (guess thats it, I am picking up some rumble sounding noise when the needle engages the record groove, but at least the speed is good and it cycles completly.

Next week I finally will get to the TV. will start with the HOT/VOT pulled and do a current metered variac slow start, checking for currrent and temps on the caps. will check for all filaments lighting up. If that goes well I will progress to a power up with tubes in and the HOT current metered and see how that goes.

I prefer to do this prior to pulling the chasis even for a general cleanup as a base line, so if it works I know that much before a general cleanup. I look at clean up as a good thing to do just because I dont like the idea of bringing into the house something that is real nasty (garage now). I will also have to start looking around for a replacement needle, I have no idea of the current condtion of the existing one, but I like to replace with a new one anyway.

has good vitals....

I replaced all the HV/sweep tubes (they all looked very very well done). Getting 25kv at about 220ma so that all looks good. got a raster but did not look full (but hard to tell since I had the CRT to the wall). Waiting for the HOT to cool down and then I will pull the tube bias adapter and re seat the HOT. after that I can pull it out and get a better look at the crt.

I did not have a video source hooked up, so that will be done also.

there was no sound at all, but this set uses the cabinet speakers, and not sure if they are hook up, I willl have to trace around and see what is going on there.

I can see its going to need a lot of tube socket cleanign etc. so the video test will be short, now that I have the HV and sweep baselined as working (mostly).

I will need to check the B+ of course to see if that is being pulled down. I did the slow power up on the caps (about 10 min total) and checked again after the raster test, not warm at all.

I finally got up the nerve to tug on the HV cage hard enough to pull it back so I could get to the reg tube. That one looked REAL bad.

anyway off to a good start

I also see there is a jumper that allows for horz adj if needed, not sure how it was set.
