Product Description

This Swan (Cubic) 350B,  HF Transceiver, is in Excellent Collector Quality Condition.

 The 350B was produced 1978 to 1980 which is about a decade later than the Swan 350C

This radio has a built in power supply so there is no need for an external one.

This beautiful example of the 350B has been stored in a dry controlled environment for over 20 years as part of a   collection. 

 I recently put this rig on the air. It power up just fine and put out good power when I tested in on 80 Meters.

 The receiver is also working great and signals were really good on 80 during the day.

 I did not test it any further due to the age of this radio. 

 I did notice that many of the electrolytic capacitors look more modern than do the caps in a 350C.

 As with most vintage gear, it may benefit with an alignment or tube replacement, but it does seem to be working okay as it is.

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

 

Read all about it:

The 350/Cs were designed and built in the 1964-1967 period, while the 350 B was  produced more than a decade later, in 1978-1980 time frame.

The 350A/B/D are minor variants of the same basic design, with the 350B and 350D nearly identical, other than for the digital display on the 350D.

The 350A/B/D, along with the 750CX and the HS700S were the last of the tube-design models that Swan built – production ceased in 1980, but residual stock continued to be sold in 1981.

Single-tube PA Design Comments. Like the Cygnet designs, the 350A/B/D models switch a high wattage resistor into the cathode circuit when in the TUNE/CW mode to limit cathode current, so the maximum power seen during initial tune-up is less than actual operating power.

Thus, RF output power during tune-up is usually limited to between 60-W and 90-W PEP, while during SSB operation the resistor is bypassed and about 125 to 175- W PEP is typically achieved.
