Multiple transistor rangemaster question.

Well, I already made a npn positive ground (ordinary with one transistor).  Now there is a 2N3903 (Dragonfly's advice) in the socket (I know, I know, sockets ... hrm).  So if I make a pnp positive ground I will have to buy some low gainers pnp silicon transistors.  I don't think I have low gain PNPs...

The best test I could imagine to compare NPN and PNP RM is with complementary NPN and PNP Ge from the same factory, say ac187/188. They must similar hfe and leakage also.

Noted, thanks Mac.  But it's not at the store near home: will have to go shopping again, and this is bad, I get compulsive.

Hope you do not need a loan for buying a matched PNP-NPN pair

I am not there yet.  But if it goes on, I will have to play guitar in the metro.  Well, spanish harp work better in that case.
