> Finally, I've been testing my 4 x FET amplifier with increased supply
> Voltage. The linear amp is the one published in the LF sourcebook /
> Technical topics / Break-in. Originally designed for 250W using 2SK413 FETs,
> I've changed the FETs to IRFP450s and increased the supply from 28 to 48Volts.
> The test on Friday at 400W went well, and in further tests on Saturday, the
> amp was sitting on the bench producing an output measured at 512 Watts. -
> I'm currently collecting components for the amplifier circuit and will be
> making a full kit of parts available for it after Christmas.
