wow!
I think that might be it. And for $5 I'm gonna find out. thanks!
ps: and thanks to everyone who sent me *excellent* links to some really
cool single transistor FM radios! really cool!
I don't know why, but the idea of a single transistor FM radio inspires me.

In early to mid 70's, I remember buying bags of surplus transistors from
Poly Paks real cheap. Then we wired them into discrete logic gates and
flip-flops to get some rudimentary type of computing device. It was an
arduous process but a challenging one. But then we saw that TTL chips
were getting cheaper at Poly Paks so that fad quickly faded.

...not to mention the wonderful quality of Poly-Paks parts. Still,
it was a very cheap way to get some ICs at the time, some of which
actually worked. ;)

PolyPaks!!! There's a name from the past. What eventually happened to them?
