It will be cool to see what different spins our resident solder jockeys can put on this little guy ! If enough get built we will have to do a "show and tell" and see how well these boxes come together !

73's 4-2-ZERO

"different spins" ??? It's an amplifier kit designed to be put together one certain way so it works. That's the spin right there pretty much lol. You can slap what ever name you want on the faceplate based on what might sell the best. Like these listings below on E-Bay. Same guy selling these, won't be long and Copper will probably start stamping them out as well.

Agreed a kit is a kit however knowing this forum …..
I simply meant mosfet swaps different ways of altering the input side and the different ways we decide to wrap and flow the chokes . No two will produce the exact same results and some of the resident geniuses will certainly find the necessary tweaks to get their moneys worth IMHO lol
Also I can only find the preliminary spec sheet for the 2 x Palomar 9530 FET transistors?? Who knows but have fun boys !!

Only save about $22.00 to put it together yourself. And the one I looked at had mosfets.


I would pay $22 to sit in on a full kit assembly let alone do it ! I bought the 100 watt ebay kit and it took me 2-3 Months to get all the parts I needed to finish ;) But I work full time plus … Just sounds like fun and a new way to break in the Yihua Chinese Dual soldering station :) lol

well i can say that i've never heard anyone here talk about building amps and selling them, and the people that do talk on the radio around here don't have the skill sets involved in producing these, so im wondering who this is, how long they've been in town, and if i've talked to them on the radio before.

anyone with info on this please feel free to PM me.

My opinion based on a few FB messages , he isn’t even a big CB radio fan just a relatively intelligent dude that installs car stereos or something and found a market for budget amps ?? I have an active imagination tho lol ‍♂️♂️

With a gate threshold that can vary between 2 and 4 volts between any two devises, it is important to provide individual bias controls for EACH transistor otherwise, matching will not occur. The lack of this is likely to cause noticeable distortion in the carrier sinewave at the crossover point.
