Dummy Load, Phone Patches, Resistors for HF
Amplifiers, Heath Manuals, and more For Sale:
.

.
Heath HN-31 "Cantenna" RF Dummy Load:

This is the traditional Heath dummy load that will handle a
kilowatt. It has a derating curve both printed in the manual
and on the can.

It is in good shape both electrically and cosmetically. The
cantenna has no rust, dents or dings.

This particular unit measures 51.6 ohms, so it could not be
a much better match to 52 ohms.

I can ship it either with or without oil. The cost to purchase
is the same, but of course the shipping will be higher with
the oil.

Paper work is included for $40.

.

Heath HD-15 Phone Patches:

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.

HD-15 phone patch

As above, but no top cover, and no meter (actually
the meter is there, but it is no good).  Internal
parts are present.  These parts are useful to build
an interface for digital modes. $15

.

Resistors for high voltage metering:

Do you have a linear amplifier that has an
error in the high voltage reading? Maybe you do
not even know it has an error!

Heath used three 4.7 meg resistors in the SB-220/221
and also in the SB-200/201 amplifiers. Almost all
of these resistors are out of tolerance today, partially
because of their age, but also because their voltage
rating was exceeded.

I was able to obtain a quantity of new resistors that
are 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.

Note that these can be used in any amp that uses the
4.7 Meg resistors -- not just Heath amps.

Buy a set of three for $3 plus shipping from Florida.
Combine with other items to save shipping!

I also have a few 0.82 ohm and 1 ohm precision
resistors, as used by the SB-220/200, available.
