The 930 has many unobtainium parts now and a phone call to see if they are even accepted is a good idea. I sold my two 930's when they were getting troublesome and have been using 940's plus a 950SD since . Also have 4 830's with 3 driving transverters and the other on the amp repair bench where it gives them full on the air tests before returing to the owners.

Clif is also fairly regular on the QRZ.com Boatanchors forum.

Has anyone used K3TEN for repairs?
He's a lot closer to CT and sure would feel better if the radio didn't travel across country.

Its not the traveling you have to worry about but rather the handling of package at terminals. It is quite possible for a package to get "beat up" more on a shorter trip than a long one. I would also use FedEx ground too.

The 930 had major problems keeping power supplies.  At one time you could buy a complete power supply module from Kenwood for $99.00, but no more.

FAR Circuits sell a PCB to build a same size power supply for the 930 but with better components and a better design.

Before I would shelf it I would have a look at the two voltage outputs of the power supply.  If they are correct, then it's back to a repairman or the shelf. 

Of course you could also eBay it as a hanger queen.  No doubt many 930 owners are interested in parts.

I don't know if this question is OBE for you by now, but my answer is yes I used him and Hell No! Don't let him touch your radio.  Details on request.

Thank you for that bit of info.
I've decided not to have the TS-930 repaired as it is a old radio.
I'm going to sell it on e-bay as a parts rig.
I'm thinking of a new TS-590SG as the replacement rig.....

I repaired a TS-930  years ago for someone....  had to replace the RF amp driver transistors,
then made the cooling fan in the back be on all the time.   And I think I replaced
the power supply transistors ( 2N3772's ? )  and there was 28 volts to the
RF amp section. .   I crossed my fingers when I powered it up, and it is still working
as far as I know. . .  I said to myself - "I will never work on a TS-930 again!"

But maybe I would again... look me up.... AG4ME  in southern Louisiana...

This is a very good decision. Those classic rigs are awesome but getting very long in the tooth. Their performance is no better than the TS 590, not enough that you can actually tell.

I was going to jump on a "deal". IC 756 pro3 with mic and speaker for $900. After the idea cooled a little, I figured I would be better buying the current deal going on the IC 7300.

TS-930 is an all solid state transceiver. There is no Plate (HV) supply. Having said that, the power supply in the TS-930 is known for failure due to temperature rise.

It is also known for driver and finals problems.

I used a pair for several years pretty hard in contests and Dxing; learned how to fix it (worked in a RF lab with all the goodies) and did many for others in the YCCC and elsewhere. Went with a pair of TS-940 around 1987.

I seem to recall reading some time ago that Clif no longer works on the 930 because of lack of parts.  Be sure to contact him but don't hold your breath while waiting for a "yes" reply.

Cliff has ceased working on many radios due to this problem. Last I heard, he no longer works on the kenwood hybrids. Not sure what he can work on anymore......
