Outdated Design

Time owned: more than 12 months

This amplifier seems to have a cult following. Theres no doubt that its physically well built, however electrically its an marginal amplifier.
The prices that people are asking for these amplifiers borders on insanity for such a old weak amplifier design.
The many faults include
Poor RF design
Poorly rated RF parts
Poor or NO protection circuits
Lots of trouble with parasitic problems
No spare parts available
Tubes that are getting expensive
If you ran this amp in a contest you will probably burn it out.
If the bandswitch or power switch goes you in deep trouble. If you have a grid filament short you could be in for some real trouble. None of the spare parts are available.
The load C spacing is marginal, if you even try and tune it into a moderate 2:1VSWR you will ARC this crappy capacitor.
The relay switching is slow and will damage newer model radios. No inrush limiting and many other design failings.
Just do a google on the TL922 and you will come across several pages on "mods" to try and correct its many design failings.
I like buying blown up TL922's and converting them to 6 meters. However on HF I would only recommend the TL922 to my worst enemy. If you have one keep it, however I would not invest money in such a marginal amplifier.
Today if I was looking for a 1 kilowatt to 1300 watt amplifier I would be looking at one of the new solid state designs like the SPE or Ameritron.
If you need a real 1500 watt amplifier get the AL1500.
Bottom line is that I hate using equipment that makes me nervous every time I turn it on or use it. The TL922 is such a beast, its better to look at than USE!
