[sdiy] 2n2646---2n5484

[Harry Bissell Jr]

That's sad. The 2N2646 is about the crappiest
unijunction available.

We used one where I work (a GE part no longer made).
when I replaced the 2N2646 in my drum machine
("stupid")... the tempo range increased from pulses
per
minute to full-ahead Techno.

They don't make that transistor anymore... a
substitute part of similar specs costs $50

Sawtooth with FET reset, anyone ???
