I just checked the parts list for my HQ-180 (non-A model). It lists
3ea. 0.1uF, 200VDC and 3ea. 0.47uF, 400VDC "Dur-Paper" capacitors and
a 0.033uF and 2ea. 0.01uF Mylar caps. All the rest of the small caps
are ceramic and mica. Of course, the filters are electrolytics. --Ed

Hmm? Maybe that is the difference between a plain and an "A" model?

electrolytics need changing anyway. also the few paper caps. i will
keep in touch after cap day. tnx agn, pete k2iqk

The Osterman boatanchor book says this:

"The newer A model features a solid state PS, 230VAC, 3 position BFO,
accessory socket, less drift and 500 ohm line output."
