HP 8656A nauseating smell

(1/3) > >>

tverbeure:
I bought this HP 8656A for very cheap at electronics flea market. Apart from a "power" button that's a bit cranky (but working if you finesse it right) and output power levels that can't be trusted, it's working reasonably well.

But it's unusable due to the nauseating smell that it generates as soon as it powers on.

I've heard about RIFA smell, but I don't see anything that reassembles RIFA capacitors on the power board.

Has anyone had similar issues, or has anyone recapped some of the capacitors on this type?

Swainster:
I seem to recall that the RIFAs are hidden inside the schaffner inlet/voltage selector assembly on the 'B' version - maybe it's the same on the 'A' ?

Swainster:
I think this is the inlet filter for the 'A' version https://www.ebay.com/itm/385395000014. Sadly, any RIFAs (if that is what is used in this filter) are also going to be pretty old by now.

DavidAlfa:
Some electrolytics can also get pretty bad, some smell like a sweaty groin after 3-day non-stop party!

Aha! I saw that element after removing the backplate. It didn’t have a particularly foul smell though.

It’s tempting to do a bunch of fixes of filter and caps, the only issue is that I will quickly exceed the $80 that I paid for a unit that I don’t have a real need for (as if lack of need was ever a reason to not to buy test equipment…)
