New Blackcat amps

psycho, I'd normally agree with you, except for the fact that my el-cheapo KL 203P has been kicking some serious butt with my Grant XL. Great reports, and great output. If it blows up, I could care less. It only cost me 50 dollars. If the BK can perform as well as the KL but with higher output, they've got a winner.
Mosfets are just like SMT..... like it or not, it's the direction the manufacturers are going.

Thank goodness I have enough old style radios and comp amps to outlive me. I will always be old school when it comes to CB. Anything else, I'll change with the times but I'll never wear my pants around middle of my ass though. :laugh:
Not me! Seems like there were a few quick and dirty methods posted on the forum. One by exit thirteen, and I can't remember the other fella. Not sure if they were for mosfets or not, though.

Interesting reads here. smd technoligy....mosfet amplifiers.....Geese what next??
All built to be used up and thrown away. I really don't see a huge market for these mosfet amplifiers like the older bipolar or tube counterparts enjoyed. They are to fickle, fragle and otherwise unreliable. Sure the 7030 devices will last a little longer but sooner or later the will give up too.
If these mosfets are to be the thing of the future then they will have to start using mosfets that are designed to amplify RF that are of a better quality like those used in ham equiptment. Sure the cost will be higher but the equiptment will not suffer from the same shortcommings as what they are using now. But we all know that will never come to pass.
They may be the cheapest watt per dollar amps on the market today but how much are you really "saving" as compared to the the bipolar models? They just seem to be another example of cheap, throwaway equiptment like most everything else thats made today. For years the majority has been screaming for more watts per dollar. Perhaps this was the answer to that?
I can't speak for anyone else but it seems to make better sense to find a good bipolar model and stock up on replacement 2sc2290's or 2sc2879's and have them for a long time if used correctly. Sure this seems "expensive" but in the long run how do you think it will compare to continously buying these cheap mosfet amps? So having said this I wonder what is driving the interest in these types of amplifiers? Perhaps it is the "itch' for having something "different"? Or being proud of having a high powered amplifier for penny's on the dollar? Who knows?
Just dosen't make sense.
Wave of the future...Yep....Just like everything else.:blink::sad:

I have had one for almost a year its the low drive version good for up to 30 watts, I am pushing mabey 30w into it and I see 550+PEP on my mfj-868 meter, now I added a 120mm fan on top and works great. these seem to be a fairly loud amp as it really kick up the modulation ...if that makes any sense?

I wish someone made a clean high performance quality built AB amplifier in either mosfet or old school finals. It's sad to see such a fine SSB radio sitting on top of an el cheapo Palomar amplifier.

Supposedly,
They are class AB.

Poor Palomar name has been spread around longer than a $2, you know what.
