All,
Am trying to build a couple of the ARRL 1990 4CX1500 amplifiers
for 144MHz by K1JX/W1VD and am having problems sourcing some of
the parts here in the U.K.
The amp uses a drive belt and three pulleys to move the anode
tune cap, these parts are shown in the project as supplied by
Small Parts Inc. [page 31-68 ARRL Handbook 1990].
Have contacted Small Parts Inc. who appear to have no knowledge
of these parts.
Am I dealing with the right division of Small Parts? Is there
a mistake in the ARRL handbook? Can anyone else help with the
parts and/or suggest or supply alternatives?
Regards
Mike G8TIC
