It's a high vacuum leak sealant. You can find it at www.2spi.com

It's quite expensive.

Yes, that sounds like the stuff. I was told it would be expensive. I just wonder if it's worth it.

A little googling brought my to Phil's excellent CT-100 restoration in which he used it on a 15GP22.

Assuming that a 0.5 oz bottle is enough, I'll have to run the $36 + shipping costs by the set's owner.

I have a Thordarson cross-reference book that would tell you what alternate flys you can use. Since you already have the universal fly on the way, you sound like you are okay. Let me know and I'll dig it up for you. BTW, it does not just cover Thordarson, but all of the common parts suppliers of the time (RAM, Merit, etc.)

I have the universal replacement, but haven't tried it yet. It doesn't fit well on the chassis and the leads to the tube caps are a bit short.
It's also used and a little undersized compared to the existing one.

I have the Thordarson guide from 1978, but it doesn't list other brands. Please check your guide when you get a chance. Thanks!

I applied Vacseal generously to the seams around two 15GP22s, which used up perhaps 1/6 of the 3-oz bottle. A little goes a long way! I have no idea what sort of seams a 19AP4 has, though.

I could only find Fly-40 as a replacement. I have another Merit only book, and it seems to skip right over the parts for this model entirely. Looking over the schematics for the Merit flys, I could not find one that was even close. Motorola part # is #24C792691

OK, thanks. The Sams mentions a Merit HVO-6 as a replacement, but I haven't been able to track one down.

There's a few HVO-7's out there, maybe they would be close enough?

Hmmm. Hard to say without a datasheet, but I looked at the other HVO-7 he has listed and this is in the description:

"Merit HV0O-7 Horiz. Output Approx 14K.V. Output with AFC replaces HVO-6 for tues up to 24 inch. "

That sounds promising! Thanks for the link.

The logistics of having the set picked up have been comical at times. If I'd had the opportunity to go get the cabinet myself I certainly would have. Two tiny kids and a dad driving off to Chicago for the weekend would make for a stir crazy wife. I have to put my family first.

Luckily my Mom was willing to get the cabinet but forgot all about it her first trip back to Chicago. She's now closing on her house there and figured this was my last chance to get the cabinet apart from making the trek myself. On her way up the Jeep died on her and a friend she took with her. A day late and having to deal with movers and fixing things around the house made me tell her to "forget it".

Gold Coast (the antique store that's been nice enough to hold the cabinet for, well, months) isn't even open today. I had to pay someone to come in on their day off just to open the door and hand the cabinet off. Luckily this story has a happy ending as Mom pulled through by finding another relative that I've hardly met to go up and get the cabinet for me! It's currently on it's way back to her house were the movers will pack it and bring it to Tennessee. I'll get to see the cabinet by the weekend.

I owe a lot of big THANK YOU's to a lot of people. My family and especially Bob for picking up the set, putting other stuff aside he was excited about working on, and for restoring the set for me. Another big thanks for all of you that helped him with your posts. :thmbsp:

As soon as this comes together I'll absolutely post plenty of pictures.

I have another bit of good news. I scored a NOS Merit HVO-6 this morning on eBay. Hopefully, that will will do the trick and I can call this project done :)

I finally received the Merit HVO-6 and managed to hook it up. It's not the greatest fit, but good enough to try out.

Nuts! The dark lines are less pronounced, but still there :(

However, I discovered that the capacitor hanging off the flyback has a big effect on those lines.
I was able to pretty much eliminate them by tweaking the value :D I think I'll button this set up and call it done!

Hey! I have those dark lines too :( I'll have to try the cap trick, though I noticed I have a bad (or suspect!) vert lin coil, too...

I had the same veritcal lines in my Sylvania after replacing the yoke until I replaced the balancing capacitor in the yoke with the correct value.
