Re Decca 1615 SG
 
It's a very old tube-type device = designed ca.=20 1960.
Tube line-up 6AM5, 12AX7, two 807's = (later=20 models 6146's)
No risk of blowing up FET's with this = one but=20 doubt
if the transformer design would be = relevant to=20 FET's.
No ccts but the guy who designed=20 it tells me it was =
purposely designed to work into all = sorts of=20 mismatchs,
shorts, etc so it could be used for = lining up new=20 antennas
of possibly unknown = characteristics. It=20 worked so well
they never bothered updating it to = solid-state and=20 it
was still current in = 1995.
It's what I'm using to put = out the test=20 signal for Peter
G3PLX.
