Hello Boatanchor fans:
I have an Alpha 76A on my bench for repair from a friend
of mine but has no book. Am looking for a schematic covering
either the entire rig or at least the power supply as the
28 volt supply is out of it. Or, perhaps a website where
I might find one?

Thanks and 73

Doug, K7YD


Doug -

Here are come Alpha 76A resources.
I have a 76A that I just refurbished beginning of year (new capacitors,
etc.)

BAMA has the Adobe Acrobat

There are a couple of resistors on the HV board that Alpha recommends be
moved up to 1 watt in size --
opposite edge of PC board from 6 HV capacitors.

Matt Erickson, KK5DR has a "care and feeding guide" for the Alpha 76A
Guide was recently updated and is a 1 Mb file (Adobe Acrobat)
