Currently, I think Texas Star is about the only one currently making class AB amps that I'm aware of. Wait... I think RM Italy makes a couple models with class AB also, if memory serves. If you get into the older stuff, Messenger had good AB amps. The old Palomar and the Magnum series amps were also good AB boxes too.
Davemade, Xforce, and all their spinoffs are class C. While you can order them with "class B" biasing, it's a crude class B that's actually very close to class C, so they aren't worth a crap anyhow. A good tech can bias any amplifier to AB and get it setup pretty well. I have done this in the past with amps, as have several people here on the forums.
You can get that Brimstone amp you bought setup with class AB if you ever wanted to run SSB with it. You'll have to reduce your input drive, and you should see about 250-300 PEP out of it pretty clean.

I have read threads that the TS are not really that good when it comes to class b ... but they do great as a class c amp
It looks like I will need to go to an older amp if I want to get a cleaner amp.
At this time I am just kicking it around.
Thanks for the info ...
Where in the world did you see this??

Do you believe that a texas star is really a clean ab1 because they list it as one?
Incoming Region Produces X3 Solar Flare |

Another major solar flare, but this time from an active region just beginning to turn into view off the east limb. It is possible that the group responsible is old AR 3654 from the previous rotation. The latest flare, an X2.99 event just peaked at 14:38 UTC (May 15). Stay tuned |
