Heya....
I've just been reading through the whole thread and thinking... 'nice setup' with the IRF4905 and IRL3705...
The interesting thing is that the same place ausmicro.com sources our IRF7389s from can also supply 3705 and 4905 in TO-220 packaging.
How much are you guys paying for a set (2 pairs) landed at your door? I may be able to undercut - and have immediate supply. Pay with Paypal or whatever
drop me an e-mail (aaron@ausmicro.com) or PM (here or on ausmicro.com)
