balancing act between drive , increasing xconductance of OS and it's rising capacitance
as Papa recently said - I just hook these things up and see what I get
in his case "see" is certainly longish process
go figure
for instance - in Babelfish J , I'm finding one pair of IRFP150N better than 2 pairs of IRFP240N ....... not just because matching is not necessary

Love the diode heatsinks...perfect for my solution.
Size of your main heatsink is ?
Looking forward to your findings driving that board really hard.
These sinks are 6" x 16". THey will not be the final destination. I will have another set that are 8" x 15" for the final build. I will use larger heat spreader as well, increasing 3/8" x 4 x 12" to 1/2" x 6 x 12"
here's mine...shorter box ( 300 mm ) but 11 cm of heatsink depth by 15 cm high
should make a really nice and compact build

Gama aluminum....... unfortunately a bit far off for you, in Slovakia.
'course if it is too hot i have master ZM's Babysitter:

Very cool buzz. Looking forward to seeing how those heatsinks work when you throw a couple more pairs on there. They look like the 10" profile sinks for heatsink USA, which I was thinking of using for my build.
If i go with 4 pairs, I will use a single 1R resistor and cut the bias in half. I don't need more power, so it is just a matter of whether or not I like 4pairs@400mA or 2pairs@800mA. IF I like the 4 pair, I may try 4 at higher bias as well, using monoblocks. The heatsinks are very similar to the HS USA 10", but not the same. I have the HS 10" waiting in the wings. BTW, I should be packing the kit stuff in the next week or so. Also. I should be listening to a standard vs upgraded version of the F5T tonight. Little comparison.
This my exact situation, i'm very curious to hear your subjective experience about these two possible choices.
I know , the subjectivity i refer to is the comparison between a cooler running class a amp and a hotter ( better sounding ? ) one as has been expressed in many post.
I'm guessing a 4 pair one should have a cleaner punchier bass...i might be wrong
My subjective reasoning is that current delivery to load should be quicker with 4 pair but that has to be possible also by the PSU.
????? let us know

Yes, welcome .......
8cylinders beat 4 cylinders ... for smoothness and delivery all the time ............. 
Pour it on , I gotcha back bro .....
hello. just got a great idè regarding P3 trimmer for this amp, and all other F5's for hat matter.
how about a multi turn panel mount pot, connected to a digital ohm meter with a smal display on the front? that way you can easely get 2 monoblocks adjusted the same.
and for a stereo amp, one gan use a stereo pot with one ohm meter and display.
what do you think? and do anyone know who can be selling ohm meteres that can be used(that you can calibrate yourself)?
