Absolutely great  Time owned: more than 12 months
Got this EU version (220/240 volt and 10 m) with a burned main switch. That was easy to find and replace, and later I upgraded the PA with the Revival Modification Kit from Kessler Engineering. Installation was pretty easy with the support from Dr. Kessler by e-mail.
Definately a keeper :-)

AMONG ALL-TIME BEST  Time owned: more than 12 months
I got a second hand one in 2012. It was in perfect shape in and out. Pretty soon I got tired of relays clacking and removed all screws holding them against the chassis, lifted them slightly while inserting a thin rubber between both relays and chassis. It did its job by attenuating noise about 80% and living it quieter than many ones. (equals the noise of my IC7300)
I have use it almost daily for 6 years driving it to full 900W in CW. (it puts 1.5KW out on SSB position)
NEVER had a problem even having done almost all kind of mistakes, including keying full power without antenna connected or with the wrong antenna. I appreciate an excellent mechanic engineering. Built like the in golden years, Very Heavy. Rock solid. AND A BEAUTY!!
Last week I did the Kesller Engineering MOD (I strongly recommend it)and now I have an amplifier that gives me joy looking at it and operating it a full QSK absolutely noiseless. I only do CW and now I can go to SSB position - 3300v in plates - and it won't heat up because you avoid the about 400W plus wasted in generating heat when idle between dots and dashes.
I'll never regret a single buck spent in this amp and the $399 mod.
I also have a Centurion TT422 and a Dentron MLA2500B with two 3cx800A7.
One thing I'm certain of: If I have to chose, I'll keep the TL922!!

A Great Linear  Time owned: 6 to 12 months
I love this linear. It has excellent ergonomics and the beauty of its panel. I recently purchased a TL-922A model, with 28mhz included, that faced a deep retrofit, including new valves. Wonderful !!! It's sure to work for another 20 years.

Great Amp Even Today!  Time owned: 3 to 6 months
I love my 922 amp, easy to tune up and a beast to move around (only nit). Wish Kenwood had made the transformers removable. Touched up the top and bottom covers and side panels and looks like new. Very good amp and very similar to the old SB-220. I am sure I will be making some upgrades down the road but for now, enjoying it as is.

Great amp. Need's updates to be dependable.  Time owned: 3 to 6 months
I picked up my TL-922 from a local ham's yard sale. He told me that he had mistuned the amp into a reactive antenna, and that it had smoked and blew the fuses. It's a good thing I got it for a reasonable price. It needed a lot of work to get it back on the air. I replaced the smoked band switch, installed the Kesseler Engineering Revival kit, directly grounded the grid's on the Eimac 3-500's,installed hairpin style parasitic suppressors, installed a glitch resistor on the B+ line, and fuses on the filament xformer primary. I also enabled the 10 meter band. The Kessler kit includes soft start, soft key, T/R vacuum relay, and adjustable bias(among other thing's). I now have an amp that is stable, and work's great. It is built like a tank, and easily put's out 1KW pep with only 40 watt's drive, AND it look's great next to my vintage Icom 781 rig.
No more stuff from Starkville MS for me !!

P/S The tuning instructions in the manual say's to start tuning with the load control set to "0", I start with the load control set to "5".

ONE SERIOUS AMPLIFIER! :)  Time owned: 3 to 6 months
I purchased this amp about 3 months ago, and it really puts out! I had a 15 amp breaker, and it would overload the circuit and shut everything down when its running hard. I swapped out the 15 amp breaker to a 30 amp, problem solved. I love the way the tubes glow, and the signal and audio reports are always excellant.I run a Kenwood ts-930s, and its a very good match. It will easily put out 1350++ watts, and the amp never overheats. Ive had a Icom pw1 and an icom 7000 before this setup, and it worked well, but there is nothing like using a tube amp...Warm sound, and puts out some serious power. It does circles around Icoms Pw1. I'm sure most of us will agree a tube amp is the only way to go. 73's! :)

Kessler Engineeering Kit  Time owned: more than 12 months
I am the second owner of this TL-922. I purchased it two years ago at a ham fest. I did not need another amplifier but the esthetics and build quality of this amplifier along with an excellent purchase fee was something I couldn't pass even though I own an Acom amplifier. I have been preferring to use the Kenwood but some of the technology is thirty years old and I had some concern of the inrush current, loud, hot switching T/R relay, slow relay-controlled tube bias and high voltage/high current PTT switching especially with the newer solid state radios. In searching the internet for modifications, I found exactly what I was seeking with Kessler Engineering. They have a package that upgrades all the thirty year old technology of the Kenwood. Installing this kit was a very enjoyable experience. The quality of the parts is excellent, they fit perfectly and the assembly instructions were also perfect. With the installation of the Kessler Upgrade Kit, I now have a Kenwood TL-922 that is compatible to any new three thousand dollar amplifier and in some instances, better! Yes, I use it all the time. If you have a TL-922 or considering getting one, I would strongly recommend you also purchase Kessler Engineering's upgrade kit. The Kit turns a very good amplifier into a great one.

Excellent piece of kit  Time owned: more than 12 months
I've had my TL922 since 2005. Bought 2nd hand from a UK dealer. While the relay is most definitely stentorian in its report, this is still a great performing and lovely bit of kit. Mine had the parasitic suppressors done and I bought an outboard in rush protector. The 3-500's died after 4 years and I bought some new ZG ones and they've been fine. I tend to run it on "CW" mode which keeps the HV @ 2KV and this provides 600/700 watts out which is adequate for most Dx. I've recently added an idiot proof SPE1K to my kit, mainly for 6m and also to protect against operator error but I still use and enjoy the TL922. Both a driven by JRC JST 245s. Tunes the WARC bands well too. If you're in the market for a great performing and nice looking amp then the TL922 is a good option, just check it hasn't been abused and don't run it flat out at 1200W plus in high duty cycle data modes.
