** FYI to readers:

these are obsolete "strip line" RF transistors made by " ST " for use in
SSB, linear amplifiers up to 30MHz ( ie the HF band).

Any ideas as to supply of 'genuine' items ?

The OP knows there are offers from on-line dealers in HK & China at about
US$ 85 a piece.

But he has nagging doubts ...

I would too.
