[Lowfer] high Q caps for lowfer and VLF?

[Art]

Hi everyone.

It seems mylar and polystyrene caps are going away at an alarming 
rate, which make building high Q circuits for LF and VLF more problematic.

Disk ceramic and especially ceramic SMT caps are small and compact, 
but the electrodes are less than .001 inch thick, hence they have 
horrible ESR ratings at LF and VLF. And, the ceramic caps have 
horrible temperature stability, as anyone who ever tried to use on in 
a timing circuit already knows.

I need low voltage caps that do not need to carry large ac currents 
(for receiver front end tuned circuits).

Are there any good to medium LF/VLF optimized caps on the market 
today, or is that I'm just not looking in the right places?

Thanks any and all suggestions.
