audio equipment made by Quad in the UK in the late 1970s and 1980s.
Normal
electros, airtight sealed in a plastic housing.

[Groan...] Just when I was convincing myself that they were
poly-somethings.

Funny thing is, they nearly all failed ( high ESR or open) after 10 to 15
years.

Yeah, I suspect the electros on this PCB causing all sorts of problems.
Just
hoping that all the "traditional" form-factor caps I'd replaced were all
the
bad ones. Now this non-standard fare...

Thanks, Phil.

If you think one/some are faulty, make a note of value/voltage and break one
open - the difference between an alu' foil electro and a tant' should be
easy to see.
