Thanks @Jean-Paul. What do you mean by "metered" variac. I have a variac. Do you just mean put a meter on it to more carefully calibrate the suggested voltage? Or, if I read-between the lines, where

thank you !

Hello Rafael, Sorry for my late response. I honestly don't know if this works on a TDS620A. I do not have any schematics of the TDS620A but if there are some configuration-resistors on the

I am looking for a seller from Greece who i THINK was named Qservice however no luck on Fleapay search, any help is appreciated. If a seller in the USA has the same avaiability of parts, please let me

hipping 577/576 is always risky, sellers seldom have the correct box thickness stregnth or packing materials. Most arrive with broken or internal damaged CRT. Take photos and keep packaging, sned

Alex, Where are you located? I may have one. I’m in the Los Angeles area. George KD6NEW

Sorry, I forgot to add - I'm in Florida. I'd be willing to drive several hours to pick one up, or pay for shipping.

Good tips, thanks. I'll look into my ebay resolution options further. I have sent a message to the seller via ebay with a picture.

"No glass" means literally that - the glass vacuum envelope is gone. You can see the broken off shards at the base of the CRT. And because the broken glass is not in the shipping box or the 577
