Motorola VT-71 restoration (TS-4J chassis, Blonde cabinet)

[bandersen]

Yes, I'm restoring yet another Motorola 7" set This is actually one of the first sets I picked up, but it was really chewed up so I left it on the back burner. The recent acquisition of some nice Amperite ballast tubes got me thinking about so I hauled it out. Also I figure I might as well finish it off while the TS-4 schematic is fresh in my brain.

Here it is as I got it. The cabinet isn't too bad, but the insides The CRT base was ripped off as was the CRT socket. Seems that someone decided to hard wire the CRT to the case. Maybe the old socket developed shorts?

I've already removed the CRT


Also one of the tuning slugs is broken off and a HV pot is frozen. Plenty of ugly old repairs too with big solder globs on the replacement parts.



Finally, no tubes except the HV rectifier (that should have tipped me off to replace it!)


Oddly, the original mask is almost good enough to still use.
