Hmm i wonder if these Exicon Mosfets are as universal as they claim they
are, maybe the amplifier i am using requires some sort of modification to
it
so i can use them.

My technical english is not that good, I guess, but here goes:

If you have two 2SK49 and measure them thru', you will get different
results. The spread (?) on MOSFETs is big. Their turn-on voltage can differ
a lot too, so . . .

If you have some power resistors, *and* you can put them in between the
power supply and the power amplifier circuit, *and* you can adjust the bias
current ( idle power consumption for the power stage), *and* you have a
multimeter, *then* you could try to measure the bias current to see, how big
it is if there is any at all. That is, if you know something about
electronics.

A simple test with a simple adjustable power supply can get the info
regarding the switch-on voltage: Plus to Gate - minus to source - multimeter
in either ohm or diode mode to drain and source. Start with voltage at zero
volts, the multimeter should show infinite ohms - turn up voltage slowly -
at some point the resistance should drop - drop to about 10 kohms and read
the voltage. Do the same with the other MOSFET ( That is: Hitachi versus
Exicon!).

And tell us the results.
