Kenwood TS-830S Hybrid Solid State + Hollow State

One day I'd love to get some old tube radios...  Like I had when I was a novice around 1966

Do tell! What rig/rigs were you running back then?

What I need to do is to grab an old picture of me at my radios and then I'd remember.

Time to put up some shelving! An AT-230 antenna tuner followed me home today from a local hamfest. Bench is getting crowded.

A look under the covers of the AT-230 tuner.

Double vision? How about triple vision?! Yet another TS-830S followed me home last weekend.  No issues so far. Been running it all week long. OK, that's it until I give the sick one on the bottom of the pile some attention!

You got enough antennas for each of your children ?

They have to learn how to share......

Ahh yes.  A Tri-Plexor  ??  Don't know if you can transmit on more than one at a time with one of those though.

Hybrid RF combiner. Frequency range is limited compared to a resistive combiner but the loss is much lower. All on VOX so when contesting I can get three contacts per call on three different frequency's within the same band. Big time saver!

Kenwood ad from 1981 showing entire station minus the scope/monitor and mic.

what? no 922 linear?

Hey Neil! It took me over 5 years....but.....A TL-922A is now in the shack and the Hybrid station is for all intents and purposes...Complete!

Snagged it a few days ago at a local Hamfest for much less than they go for on epay. Near mint condition and shows no signs of hard use and or abuse. Pics? Nobody ever wants any pics.......

More pics....

And a few more....

Tubes are the original Eimac 3-500's with date codes from 1985. Amp was sold new May of 1986 to a Ham local here in Seattle.

All the little Kenny's back together again.

PO of this amp had replaced the HV choke with a glitch resistor. AKA a cheap HV fuse. Problem is the style used, standard rectangular cement filled, tends to explode during a HV short. Not good! Installed a much better glitch resistor that does not typically explode when shorted, plus it's pulse rated so should hold up fine. There will actually be another one in series along with a MW 1AMP 5KV fuse between the 3.2KV B+ PS and the 3-500Z tubes.
