 Resistors for HF Linear Amps For Sale

Resistors for HF Linear Amps For Sale:
-
Have you replaced the filter caps or do you
have an error in the high voltage reading
in your linear amp?
-
Most amps used resistors that got too hot for
bleeders/equalizing near the filter caps. I
have some 120 K ohm, 3 watt, 1% resistors
that are really great for bleeder/equalizing
resistors in the capacitor string. 1% equalizes
much better. $0.75 each
-
.
Many amps used three 4.7 meg resistors
in series to meter high voltage. Almost all
of these resistors are out of tolerance today,
partially because of their age, but also
because their voltage rating was exceeded.
-
I have 4.7 Meg, 1% tolerance, 2 watt, and are
rated to handle the high voltage. This compares
to the original resistors furnished by Heath that
were 4.7 Meg, 5%, 1 watt and about 400 volts.
-
Buy a set of three for $3.
-
.
Prices do not include shipping from Florida.
-
Thanks. 73,
