[AMRadio] HB Xmtr, was: Home Brew AM Transmitter Wanted

[Brett gazdzinski]

Peter Dahl sells reactors.
I have one, 50H at 400 ma (pair of 813's run 400 ma).
I think it cost $250.00. Its nice and small.

My rig sounds better without the reactor.

I have one of those big RCA mod transformers in there, they sound
great, much better then the CVM5 I had in there.
