The 21AXP22A is at Scotty's and it looks like the rebuild will be attempted this week. He waits until there are several days with no predicted bad weather, since a power failure would cause problems with the oven.
I am still seeing if I can verify a list of caps for replacement. Doug drh4683 gave me a complete list, but I am still trying to locate them all and make up my order, especially a nuisance since RCA and SAMS numbered things differently.
Meanwhile, all I have accomplished is to remove the chassis and the CRT from the cabinet. I plan to remove the tubes and check them.
Any advice on cleaning the chassis would be appreciated at this point. Can this stand up to a wet cleaning, or should I not risk it? I know that is how Tektronix scopes used to be refurbished, but they also may have replaced controls or other things that I wouldn't want to risk having to replace en masse.
