Heath SP-27 Low Voltage Power Supply:

The Heath SP-27 is the factory wired version of
the IP-27 kit version. It is a lab type power supply,
with adjustable voltage and current limiting.

It has a large 3.5 inch meter that can be
switched to read current or voltage.

The current limiting is set in 50 ma, 150 ma, 500
ma, and 1.5 amp ranges, with a pot for fine
adjust. One can set to the current expected,
and not let the smoke out as easily.

Specs say the voltage is adjustable from 0.5 V
to 50 V in 5 V steps. A pot permits fine adjustment.
On this unit, the ranges above 20 V are somewhat
compressed, and maximum output is 36 V DC. We
used supplies like this for over 25 years at the
college where I taught. Most of them do this
compression as they age. It is of no consequence,
as very seldom would one use over 15 V, and it
is perfect in the lower ranges.

Buy this power supply, with manual, for only
$55.

Heath HD-15 Phone Patch:

This is the unit with the VU meter on
the left and 3 knobs that match the
SB series to the middle and right. Low
or high Z output to the transmitter.
It can also be used as an interface to
the computer for PSK31, etc.

This one is in extremely good condition.
No scratches or imperfections.

Paper work included for $25.

.

Resistors for HF Linear Amps:

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.
