yeah Mike that is going to be a tough one. with a limited supply of tantalum left, the price is going to go up more, and probably never down again.C179 it is. I just changed one.
Checking my supplier, I'm finding tantulums have a premium cost to them. Are they worth 10x the cost over the same value in electrolytic? That's going to be a hard sell.
I can tell you that i have changed so few tantalums in the time i've been doing this stuff that can't even remember when the last one was. i think it was a C179 in an 858 chassis though! LOL
that one should have been an electrolytic from the factory.
I am by NO means an authority on tantalum caps, or any other cap for that matter, but if you are considering this; i would advise you to start diving deep into the subject online.
you will find some people that think they are the devils capacitor, and some who can't sing it's praises enough.
i can tell you this, i've re-capped quite a few radios, and i never replace the tantalums, and i've yet to have one come back with a blown cap.
not sure how objective that is, but it's all i got.
If it were me, i might try offering a tantalum set of caps separately for those who want to do it.
