I'm looking for genuine FQA12P20 / FQA19N20. Let me know if you have some and you are willing to sell them. I need 4 pairs but let me know even if you don't have that much.
There are probably more FQA19n20C floating around amongst diyaudio members
due to a couple of GB's in the past. What is your intended usage? Do you need
any matching between each polarity?

I have 2 F5 clones with IRFP's in them. I just wanted to try and compare them with FQA's.
I believe any matching is not needed because only one pair per channel is used.
I wasn't aware of FQA19N20C. what is the difference to FQA19N20 ? C-version could be used as complementary to P20 in F5? Then sure this is of interest.

The production F5 appear to have used the 20C; please see one of the photos here:
