Was told they are a lot better than the bv150s that i use. Had one of red ones before lasted 4 days till it popped. Hence why i now have bv150 splatterbox.
Kill em all and let god sort them out.

kl203 works acceptable as long as you do not exceed 2W AM/FM and 10-12 SSB on input. Looks not that bad on the scope and spectrum analyser.
More drive, more distortion. Tested by myself.

For longer talking I suggest to put 12cm fan on top of it.

I normally put around 7 watts AM/FM and 18Watts SSB into mine and have had no issues.

Just be careful using it with a radio such as a PC-999 Grant, as they might give 8 watts on deadkey but with modulation power will rise high enough to hill the amp.

There is no such thing as a Fidelity 1000 which is too good to scrap.

Well according to the specs I am not overdriving it.

No complaints yet, exept on one occasion a radio I was using had a fault.

I do use a reasonably good low pass filter.

Finally, Someone who agrees with me that the KL203 [MOSFET] is an awful amp, Just by seeing the SWR jump when powered on indicates the amount of rubbish being spewed out of them, I dont have the pleasure of owning a spectrum analyser but i would love to see the results of a KL203 with 5-15w input.

I sold my analyser over year ago since I do not play with those toys anymore, but I still have a scope and when I get one of those boxes I will make some screenshots.
