HP5065A Rb Fq St. Upgraded A7 (AC Amplifier) and A15 (PSU & Regulator)

[Uky]

Greetings.

Updated designs for the A7 (AC amplifier) and a slightly improved design
for the A15 (DC Regulator board) has been uploaded to KO4BB manuals site.

The A7 is a "drop-in" replacement.

The A15 requres replacing the transformer based AC/DC rectifier circuitry
with a switch-mode 24V supply (and additional filtering). And I recommend that
the +20V output is (coarse) adjusted prior to inserting the board in the 5065.

Cheers.
