[Amps] silver mica source

[Alex Malyava]

Hi all,
I need some silver mica caps to be used in 100 W PA LPF and tuner
What are the options besides mouser.com at $2 a piece?
I found one place - thetubestore.com in Hamilton, Ontario - with prices
like few times cheaper that mouser, but I am not sure how reliable those
mica caps are.
I think the caps they sell come from India, from simic electronics...
Are they good? Do they have high Q and low losses as should be for "normal"
silver mica dipped capacitors?

Thanks,
