1968 Westinghouse JetLine
My neighbor gave me this 1968 Westinghouse JetLine tv. It keeps blowing the fuse attached to the line and the power transformer. I'm not used to working on these transistor sets, any idea what's causing his?

Here is the photo of the chassis. It uses a 19CMP4 crt. I don't have the schematic for this set yet. Has anyone worked on one if these sets?

I had one, about two years older, all tube. Hot chassis, voltage doubler, probably TOTL and a great performer. Seemed to be a low hours set, CRT perfect!

The gig filter sounds like a real innovation.
Wunner if they had a patent on it.

The "sun screen" made the set look like it wasnt a TV when
off. It was like magic when you turned it on & a bright picture appeared. Tube models were more common but still not every day sets. This was a big $ set. W was about to pull the plug on consumer electronics at this time. Personally I hated them but this is IMHO is a milestone set. W had the ability to build very hi tec stuff but CE was a $$ looser. IIRC they built the camera that showed N. Armstrong stepping on the moon. 73 Zeno

I did a continuity check on the electrolytics to see if any of them are shorted and I get continuity on several. This could be my problem... I'll order replacements and restuff them and see if I get any success. It seems odd though that a set this late would have that many bad, but I guess it is 50+ years old.

What amperage rating are the fuses you're putting in?

Found a silicon diode in the hv supply get hot at 30%, so I replaced it with a new one and replaced the hv rectifier. The set works great now!

Zeno,
Interested in why you aren't a fan of W television sets. And your experience with their repair and servicing perspectives. Your thoughts, please.

The color chassis was a bit cheaply made & messy looking. Also very tube hungry sets. B&W's were better but many suffered from slipping tuner wafers & yokes. Hard to describe but they always seemed to be missing "something" like an Emerson or GE with a few years on it. And the owner hated them to. Had one someone got for free. Great cabinet but high miles. He begged here NOT to fix it but she could only see the cabinet. Took a bunch of tubes then she pulled the old "my husband has the check book" scam. A week later the FBT burned up & she wouldnt buy one. Never got a dime from the bitch. A few yrs later at another shop I sold her a bottom line GE range. I told her it only had one rack. 2 days later she was in screaming for a free rack. I told her to call GE, it was hers. She was really pissed off but I got some vengence for the W TV screwing. They see & hear what they want to not the facts. 73 Zeno
