[Amps] Street Price on a Alpha 77 SX

[Dan Hearn]

Hi Mike. I have a 77DX which has a hole for an additional tube and a second
filament winding on the plate transformer for another tube. I toyed with
the idea of adding the second tube but the regulation of the plate voltage
with one tube concerns me so didn't do it. I believe people who want the
power of a second tube replace the plate xfmr with an external one. If you
go to eham.net you will see several comments about the plate xfmr in the
SX. I believe the SX has the same xfmr as my 77dx.
  The 77DX's sell for around $5k I believe.

73, Dan, N5AR
