Hi YashEE,

The resistor originally was a carbon composition that has really good protection properties, but otherwise a poor performer. Metal oxide resistors might not be as safe in this application. Carbon Comp (not to be confused with carbon film) resistors are still manufactured by Ohmite and probably a few others.

The 430V Axial leaded varistors are no longer available. I suggest getting 10mm disc types and squeezing them in. Any voltage rating from 380 to 430 should work as long as you replace all of them so that they match.

YashEE:
Thank you drtaylor for re-posting your cogent pointers here (I was asked to delete my duplicate post on the 8060A topic)

Cheers,
Ya.

Got my 8062  :)

28:50 € shipped from Austria, picked it up about 18:00 today, now its slightly passed 20:00.

Some external cleaning with soap.
Cleaning of the MCU-connector with IPA.
Tried to pull out the LCD but it was rather not wanting to give away, but after that the LCD worked properly again!

If those caps are the originals, change them now because they will leak.  The caps look like they were made 1985 month 5?

It looks very clean now, but it's on the todo-list (I have the ordering-numbers for caps that fit)

A few weeks ago, at work, I repaired a 8060 at which had 5 or 6 caps vomit over the board (ugly!). Those (that barfed) were darker in colour than these, some of the still intact caps were the same colour as in mine, are the light-blue ones better than the dark blue ones?

That 8060 is from -81 or -82, it has more caps than listed in the manual one can download, does anyone have scans of manuals for the older versions?
My 8062 is older than what is covered by the web-manual also.
