6JB6 Matching Procedure

I received numerous requests for Bill Frost's description of a procedure to match the 6JB6 finals in 4-line equipment. Rather than send to many individuals, I think the interest is high enough to share the procedure with everyone. It is brief. By the way, I am told by others that Sylvania 6JB6's don't require matching because of their quality.

73, Wayne, KG5BI


Dear Wayne,

Thanks for the e-mail. The 6JB6 tubes were matched on cathode
current. A fixture was designed and built by the Engineering Dept. that
kept the operating voltages constant while measuring the cathode
current. A similiar test can be preformed by using the T-4X or TR-4 as
the test fixture.

1. Turn unit off and disconnect power supply. Place the unit upside
down and remove the bottom cover. Re-connect power supply.

2. Key the transmitter, with the transmitter gain control at minimum (the
transmitter should only be drawing idle current).

3. Measure the voltage at pin 3 of each final tube. The voltage should be
within .1 or .2 volts to be "matched". Substitute tubes and re-measure
until all tubes are "matched."
