Hi all
Anyone familiar with this 432MHz amplifier model, built around 1980?
The tube is a 3CX1500C7/8938 and it is a stripline type amplifier,
similar to the one
described by K1FO in the ARRL UHF/SHF book, but this one has slightly
different
sizes on the box/stripline and a different input circuit.
The stripline is made of thick (3.2mm) circuit board material and the
plate tuning capacitor
is only one "flapper".
Is there anyone who knows where I can find the description of this
amplifier design?

73, Einar
