I have a TNT 250 amp I been running awhile. Gets out great but the preamp dont work and the variable pot needs to be replaced if want to turn it down w/var. I just ran it wide open all the time so it didnt matter to me. Has 2-2290s in it 1 was replaced as see in pic. This thing swings right up there and people always tell me swinging hard and sounding great. It is a bit beat up but dont let that fool ya. Asking $130 shipped. Paypal only.

It looks like the B biasing circuitry was removed.

This is how I bought it? What parts are missing for the B biasing? I know nothing about amps. I know it works good and sounds goos on SSB still?

I'll post a picture of a Magnaforce 200 insides, basically the same amp. I am just letting you know because I recently sold one and looked inside. I know you are a top notch seller! Sorry for the fuzzy pictures but don't ask me how this biasing works, I am clueless about it. These are pictures from several months ago and my camera is a POS. Your amp is a super clean Class C driver now.

Your right it is a class C now? I found a TNT 350 video shows same parts missing from this one. Goes to show how much I know about amps ;) Thanks for the info I would have never known. Amp works great and I been talking SSB on it w/no complaints so thats a good thing. Now being sold as a class C amp.
