Heath SB-610 monitor scope:

This unit matches the SB line of Heath equipment, and is
made to monitor your transmitted signal, and can also be
used to monitor receive signals. It uses a 3 inch CRT.

I have used it to monitor transmit signals, and it works fine for
that. I have not used it to monitor receive signals, so can not
verify that part, although I believe everything works fine.

It appears that the high voltage capacitors have been replaced.
At least there are no problems!

Cosmetically, it looks really great. No scratches or defects.

With paper work for $125.

.

Heath HD-1234 Coaxial Antenna Switch:

This coax switch has SO-239 connectors arranged so the
coax comes out like the spokes of a wheel. It will switch
up to 4 antennas, and also ground all of the unused
antennas. It also has a position to ground ALL antennas.
It will handle full legal power.

This particular switch works 100% and looks fine also.

With paper work for $30.

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 1.0 ohm resistors used
in the metering circuit for $1 each.
