HALLICRAFTERS SR-150
INTRODUCTION
The SR-150 was produced by Hallicrafters from 1961 to 1963. It is a 19 tube cw/ssb 80 thru 10 meter
transceiver. The transmitter input power is 150 watts pep ssb and 125 watts cw. The transmitter and receiver
are VFO controlled. Other features include receiver incremental tuning, RIT, allowing the receiver to be tuned 2
KHz on either side of the transmitter frequency, dual conversion, VOX, PTT, CW break in, 100 KHz crystal
calibrator, product detector, combination S METER and RF output meter, and crystal-lattice filter. Both AC and
DC power supplies are available and are a separate component.
Of all the transceivers Hallicrafters produced the SR-150 is arguably the best performer within its range of
functions. In recent years (circa 2013) it has experienced a renaissance in popularity. Once properly refurbished
it is an outstanding performer. It is rare to find one that is original and pristine most have been “improved” to
the point of worthlessness. But with a little tender loving care it can be brought back to life. For those with little
or no experience with the SR-150, where to start, and how to proceed can be a daunting task. One section in this
document deals with this resurrection process. The REFURBISHING AND REPAIR section takes a systematic
approach to rehab. If it is followed in order you will minimize the frustration of restarts and backups. It assumes
a working knowledge of radio and tube circuit theory. For the most part it will lead you to the stage or stages
where faults have occurred. At this point you must have the skills to locate the failed component.
Over the years technical data on this system has scattered to the four winds. The purpose of this document is to
assemble as much technical information as can be found into one clear and easy to read document
