For Sale

Any of the items listed that are vintage electronics (some as old as 35 to 40 years old) are being sold with No Warranty, No Returns, and No Refunds. Also, due to the fact that I do not know your knowledge and experience especially as it relates to operating a vacuum tube PA  this means that all KW Hybrid Transceivers listed are being sold as "For Parts Only".   If there is an exception to this policy it will be noted in the item description.  Lastly, I only ship CONUS. 

Contact me at for all items listed here. Thank you. Terry K9TW

I have 20 Panasonic NF4EB NOS (new old stock) relays. These relays replace the Omron LZN4 flat pack 4PDT relay in the TS530S ( on IF board)  and TS830S (on AF board). The Omron relay is the cause of intermittent operational problems such as slow to return from transmit to receive,  bias switching,  and metering.  Asking $20.00  each shipped. 

HP-435B  Microwave Wattmeter with 120vac Line Cord.  No power head.  Does power on. However, it is being sold as "for parts only".  Previous owner has affixed a large piece of masking tape that has adhered strongly to the top cover.  Afraid to remove tape due to potential to damage the painted surface. The calibration reference output consisting of a 50mhz signal at 0dBm (224mv) reads a little low at approximately 210mv.  There may be an internal adjustment for this feature.  The Reference  Oscillator can be used to check cal of a Frequency Counter and can connect a dB step attenuator to the output to obtain lower signal levels to check cal of an RF millivolt meter.   Asking $ 35.00 plus $25.00 shipping.  

TS530S/TS830S Power Transformer.   This is a very heavy component in a small package.  I will incur the cost to insure it is packed so that it cannot break thru the cartons during transit. Asking $20.00 plus $30.00 shipping. 

Kenwood Hybrid 900vdc HV Plate supply filter cap kits. Consist of the two Nichicon 150uf 500wvdc capacitors, two  .01uf disc ceramic RF bypass capacitors, and two 470k ohm bleeder resistors. Very common for these voltage doubler capacitors to exhibit swollen and cracked rupture vents and for the high side capacitor to fail in service resulting in approx 450vdc plate voltage (indicated HV on the Panel meter).  This typically results in 1/2 power output. These are new parts. Cost $25.00 per kit shipped. 

Kenwood Hybrid -33uf 160wvdc -C bias supply filter caps. This power supply provides negative dc bias voltage to the Driver tube and Final tubes.  When these caps fail it results in loss of cutoff bias in Rx and loss of operating bias in Tx which sees the Final tubes go into Thermal runaway and be quickly destroyed.  These are new parts. Cost $15.00 shipped. 

Kennwood Hybrid PA cage  1000pf 3kv Class 1 Plate block/coupling cap and .01uf 3kv RF bypass cap. The Plate block cap is located at top of the RF Plate choke and the RF bypass cap is located at base of the RF Plate choke.  These are new parts.  Cost  $15.00 shipped. 

Kenwood Hybrid Driver tube 300 plate supply and Final tube 210 screen supply filter caps. This consist of two 33uf 450wvdc caps for the 300 power supply and two 22uf 450wvdc caps for the 210 power supply. The four factory caps are located on the TS530S and TS830S IF boards.  These are new parts. Cost $20.00 shipped. 

Have several TS-520 and TS-820 parts radios.   May have some parts missing, They are not fully functional.   Asking $75.00 plus $65.00 shipping. If shipping cost is less I will refund the difference. If shipping cost is greater than $65.00 I will pay the difference. 

Kenwood TS520, TS520S, and TS520SE factory side cover plate with good black plastic snap in fasteners. This is the removable cover plate for the window in the left side of the bottom cover that allows access to the trim pots for adjustment of parameters like Bias voltage for Zero Signal plate current,  RF Relative Power indication,  VOX adjustments etc. It is common for this cover plate to be missing.  Cost is $27.00 plus $17.00 for packing materials and shipping.
