I have not got one to play with but the? BSX-20s work better on small signals than 2N2222 because of lower input capacitance and have no VHF roll off? until well above? 300 Mhz - pull up? a datasheet.? Futurelec.com list them but say no stock. Send Futurlec and email .. often they can find stuff? . BEWARE the 15V VCE max.? Beware destroying the PAs Too. Beware the small size of the output transformer on the PAs .? there should be a D sheet uploading with this post for the BSX
