$15.00 US (minimum) for shipping to countries other than Canada. If you're
interested in trying them, I have a most of a tube of them in my parts bin.
I used a few of them for 40 & 80 meter receivers a few years ago, and still
have about 20 of them left. If you wish, I'd be glad to mail you a few to
experiment with.

Thank you for your offer. I will remember it, but first I would like to
try find it in local electronic stores.
And I still prefer a little bit more complicated and challenging
constructions, with each stage on separate transistor or IC. I found
only few polish publications from early 70's amateur radio press. All of
them consist germanium transistors, manually made coils and few
transformers in AF stage.

There recevers for 40 and 80 meter band, which You mentioned... What was
that? Superheterodyne? Homodyne?
