2SCxxxx replacements

I have seen a few posts on lists about possible 2SCxxxx replacements and chinese fakes and as some know I build a lot and I have used these before I have been asked to test a few supplier options one being the ebay trader most know. I'll put these into a simple TX (the Junk Box Special) and an AB linear and test CW and SSB on bands between 0.5MHz to 30MHz which is where the original 2SCxxxx were used without problems. The results will then be put up here.

I might even go as a far as the push pull 2sc2166 linear designs.
