Tektronix TAS220

Hi, one of my old scopes stopped working yesterday. I kinda like this unit so I'd like to fix it. Last time it broke down, one new electrolyte cured the problem and it has been in service for me for years. Well, the error is probably related to something in the CRT-drive circuit, since the lines and cursor-text are displayed *very* low intensity. If anyone has got some schematics or service man. for this unit, or any direct hints, I would appreciate it. Best regards, Stefan Audio power amp designer.

there are the experts. But -as far as i knew- there are no -"down to the components"- service manuals available for those kind of scopes from tek.
