This probably the E-Bay seller he got it from. Too rich for my blood.

I'm surprised it's described as AB1.
I don't like the gauge of the wires used in the amps build, but then again I don't claim to know much about the inside workings and what gauge wire should be used in an amp build. 4kw+! Wow that lodts of wattage! I'm not one who needs that type of wattage. If conditions are decent and I hear them I work them. And that's with 500 watts and an IMAX 2000 8' off the ground.
He'll certainly get out locally. All he'll need is the other local 150 miles away to also be pushing 4kw's. Over kill imo. But to each his own. I'm going to assume he wants to work the super duper bowl. Lol. I still wish him lots of luck. I hope someone gates him. I'd love to hear the way he sounds. Better yet I hope I get to contact him (once I'm back on the air.) 73

has anyone had one of these amps?any reviews .are they worth anything..looking at a 2-pill..never heard of them..would the texas star 350 be better.or a .x-force but they don't use 2879 ..

Texas Star.

Ya.
Got to love that.
It is funny that that gets included in the description on a lot of CB style Amps.
Great selling point for those who don't know any better.

Looks like class C. It is listed as AB1 but I believe that only applies to tubes.

Hey, Shade. Your correct. That 16 pill is biased class C. He has the base of the transistors tied to ground thru resistors. That photo you have isn't angled correctly to see but this one is. P.S. Most of us know better about seeing the "AB1" stuff on transistor amps Ha Ha Ha.

I guess you could buy it and run it until it blows up then return it saying the item wasn't as advertised....lol being a class C and not AB. All sellers are responsible for their listings right??

I think you are technically correct, the term class AB1 and AB2 applied to tube amps. He should have just said class AB. It would be even better yet if that amp was actually AB and not just another class C box.

The transistors appear to be mounted on the copper board. Isn't that fiberglass? How would that be effective? Must be solid copper. Maybe.

 

[Unit 75]

Yes, That is all copper. It's new. It has the strips on the transistors base so the resistors can go from there to the ground to keep the conduction angle correct, seeing class C generally needs negative bias of some kind.

 

[2NC995]

No comments on the solder, lol.

It’s not even wetted to the board.

Good eye, Dan,

Wonderful
that amp look magnificent and is a piece of art..
