thought about that, but when I tried the Philips ECG ECG508 / R-3A3 45KV Silicon Rectifier in my CTC-16XL, it self destructed in 90 seconds for some reason.

bit worried about trying one again.

Are those actually silicon? I always suspected they were a selenium stack, and never trusted them.

shango066 also tried one in a roindie, and it fried in 20 min.

so I tend not to trust them.

if anything SS, perhaps this or something like it.

I never had one fail, so I don't know if they had a string of silicons or selenium stack. If I knew they were selenium, I never would have used them, knowing that the focus rectifiers were.
I used the EDI brand, not the ECG. :thmbsp:

i did a quick look, but sadly any compatible EDI brands are quite unobtainium.

So the choices fixing it to the original spec, which I will try first, then go with that huge 1A 40kv SS diode later if all else fails.

Turns out that site with the 40kv ss diode is fake, the entire site is nothing but a rip-off.
However, I did find a EDI Solid-Tube R-3DS3 7541 on eBay, a 3DS3 is not compatible, but as a last resort, the SS R-3DS3 can be made to work, as it's well within spec.

There are 82 adjustments on a CT-100. This includes only one channel strip. It includes the six position and tilt adjustments of the yoke, which are
all very criticasl for perfect convergence.

I adjusted every one on my TV, and they all DID make it better! (except the RF on the strips, which were OK.).

In fact I added an 83rd one, one additional adjustment in the color matrix ..
and that really did get it better, even after changing all the fixed resistors to 1% ones.

HV wire will be here tomorrow, FBT coated VERY well with dope and cured, and ready for new wire, I doubt it can arc any more.

one way or another it WILL work.

Here is the link to what could be a useful site to check out a website.
My search was for kalesafe.com and you can see the results. There is a search feature at the top. https://www.scam-detector.com/valida...fe-com-review/

As Tom Petty once said, “the waiting is the hardest part”

Amazon SHOULD bring the new HV wire today, with which I hope to re-wind the newly doped FBT and try again with the 3A3C.

Did a resistance check on it.

It all mostly agreed with what SAMS says except fot the one 4.7 ohm reading which was about 10, but I have seen this before, where what they had listed did not match real time with what was in the sets and there was nothing wrong.
Especially when there are 2 different FBTs listed in the SAMS, Hoffman # 033-013000 & 033-012700
both replaced by merit hvo-234c / stancor ho-601c / triad d-304.

And if worst comes to worst and this CRT is no good, ETF does have at least 1 or more that will fit in this thing, :O

The only Hoffman set I worked on, a 23" CTC15 clone. The flyback Sams specified was the wrong one. It was for a 70deg round tube set. It didn't work properly!
A friend worked for a Muntz dealer, so I ordered a flyback from him. Worked great and it was a lot cheaper!
That was about 50 years ago. :sigh:

OK...
this just got a bit stranger.
the replacement FBTs listed in SAMS are FOR the RCA CTC-15 .
was the same one used in the 17?
this is odd
its not SAMS that makes the subs, but merit/stancor/triad right?

The CTC-15 was a roundy the CTC-17 was a rectangular...The deflection angles are different between the two so RCA definitely used different flybacks in the 2 chassis, and I have a hard time buying that Hoffman could have made a roundy fly work in a rectangular set.

Then the list in SAMS must be wrong, just as DJ ran into 50 years ago! :yes::D

The Sams was wrong!
