Resistors for high voltage metering For Sale:
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.
