Heathkit SB-301 HF Receiver 10-80 Meters SSB/CW/AM/RTTY with 3 Filters, In Collector Quality Condition

This Heathkit SB-301 HF Receiver, covers 10-80 Meters, and SSB/CW/AM Modes, with 3 Filters, is In Collector Quality Condition.

 This Receiver is part of a Heathkit collection and has been stored in a clean dry environment, wrapped in plastic, for over 20 years.

 The paint and finish is original, and there are no bad marks or scratches.

 The original power cord is also included.

I briefly tested this unit on my bench and found it to be receiving very well, with no apparent problems on the 80, 40, and 20 meter bands which is what I have antennas for. 

 The controls are a bit noisy as can be expected, but functional. A quick shot of contact cleaner will make them noise free.

 As with most vintage gear, it may be improved with an alignment or tube replacement but it does seem to be working very well as it is. It would also be prudent to replace the electrolytic capacitors before putting it into service.

It is really rare to find this receiver in such beautiful condition with all three filters installed. You will be hard pressed to find a nicer one!

I am selling this beautiful receiver as is, as described, for the family of a silent key.

Product Description

(From assembly manual)

The Heathkit Model SB-301 Receiver is capable of receiving SSB, AM, CW, and RTTY signals on all amateur bands {of the era} from 2.5 to 30 megahertz.  Separate AM and CW crystal filters can be obtained.  These crystal filters are switch selected from the front panel for these modes of operation to assure optimum selectivity and performance.  If these optional filter are not obtained, AM signals are received using the exalted carrier method, and CW may be received in either SSB mode.

The preassembled, prealigned LMO (linear master oscillator) and crystal-controlled heterodyne oscillators assure highly accurate and stable operation.  The use of the circuit boards and a wiring harness provide a clean chassis layout.

Other features of the Receiver are special antenna and power connections for VHF converters, a 100 kilohertz crystal calibrator, provisions for 15 MHz WWV reception, for transceiver operation with the SB-401 companion Transmitter, and a smooth, virtually backlash-free, dial tuning mechanism.  The transformer-operated silicon diode power supply is a long-life, low-heat power source.

The SB-301 is a vacuum tube receiver despite the use of rectifier diodes in the power supply.  There were several "hybrid" transceivers made utilizing a solid-state core with vacuum tube finals.  In my own opinion, the SB-102 transceiver, made from 1970-1975 defined the pinnacle of Heathkit's vacuum tube technology.  From this point forward, competition from overseas with fully assembled rigs with more features for the same price would usher in the end of kit building a complete transceiver.
