Does Pre-Matching 9610's Really Work?

IRF

Also, you can get dual P channel Mosfets at similar specs.
TI had some, and I just saw one from Vishay:

This is only rated at 20 volts, but very likely will take much
more without a burp.

Did you ever try IRF7304 and IRF7306?

They are not expensive and easy to get.

Thanks for the reference, I haven't tried them, but I'm
certain they would work. The 70138/70138 look to have
a better capacitance figure, though.

thanks

Nelson,
thanks for your quick answer!
Reason is that the vishay fets aren´t that easy to get in diy
quantities in Europe whereas the IRFs are sold by eg.
RS-components all
over Europe for a reasonable price.

Well, I've said it before, but matching of diff pairs for audio
is not the be-all end-all approach.

4.00 British Pounds for IRFP240 in single quantities...? Wow!
