Admiral Roundie Something explodes

couple other things to check out with the CR-70, check the pins on the socket that the adapters plug into on the connector coming from the tester. I had one that had a bent pin, so when I attached the connector it was not realla hooked up. Those pins are thin and can get bent.

I have found that a "bad" tested B&W can ofter produce a pic, not great but good enough to at least trouble shoot the set. Then when you get a backup CRT that is good, thats when you give the rejuv a try. I have used the CR-70 rejuv and had good luck with it, but again why mess with it until you at least know how the CRT looks in operation BEFORE trying to improve it.

Same with Color CRT, even a weak gun is not the end of the world, you can do a lot with the bias and gain adjustments to get a decent pic. Back when you could just get a new CRT then fine rejuv, but now I take a much less agressive approach.
