I might consider switching to 942C's later but I'd really like to make sure
it works and won't blow 200 bucks worth of caps.
Also still interested in knowing if those Russian caps will work - if they
do I'll certainly go for them. I've never heard of
Polyethyleneterephthalate foil caps before.
That would be mylar, which is generally not the best dielectric for TC
service due to a high dissipation factor (AKA lossy at RF). Here is an
older thread in which it is discussed:
If you can get the caps extremely cheap, you could always overbuild the
MMC to help reduce the internal heating, but do keep in mind what you
are working with.
The 942C caps are a bit spendy at first, but they are a proven
contender, and if you operate them within specs you will get a long life
out of them.
