Aleph30 with IRFP044's: Bad Idea?
I'm planning to build an Aleph30 and I happen to have a number
of IRFP044's on hand.
The rails of the A30 are at +/-25V. Given the drain-to-source
breakdown voltage of only 60V for the IRFP044's, I suspect they
may not be suitable.
Should I give the 044's a try or would that be flirting with
disaster? Or perhaps I should just get some IRFP240's?
I'd rather try a Aleph-X, which has lower rails for a given power and is claimed by someone to be even better than the regular Alephs.
I'll try it myself and then will compare with my Aleph 30.
I believe 044's will work just fine. Might have to adjust
any Drain-Gate compensation.
Where to find them?????:scratch:
Hi, Im a Newbe in making Amplifiers, but after some reading of several threads it came a bit clear to me. How the circuits are working and what everything stands for.
I want to upgrade my system (Commercial NAD 317 integrated amp, NAD 514 CD, Dali 505 Speakers, in which the filter allready had ben changed)
Amp has an extra set of Pre out.
I was thinking about A 30-40 Watt Amp. Don't need that much and planning to get rid of the amp by making an BOSOZ.
So me eyes felt on the Aleph3 / 30(thanks to MR Pass). and the A40. First I will try to make the Aleph. If that works, make it a continued story.
But in a store Near Rotterdam (dordrecht) Ther where no IRF 244. :bawling
Does anybody in the Netherlands where to buy the Matched IRF244, or are there substututes without makking any changings off bias and current gain?
Thanks for the advice! Will give the 044's a try.
You could try IRFP244.
It has about the same specs as the IRF244.
Ooh, and welcome to the forum.
Most of the people there also post here, so perhaps they answer here.
(see e.g. http://www.diyaudio.com/forums/showt...threadid=19390 or http://www.diyaudio.com/forums/showt...threadid=15906) Perhaps you could also try to contact them through this forum.
