Hai Friends...! I have 4 pcs 2SK 725 and 4 pcs 2SK 727. I want to bulid Class A Power Amplifier with these Mosfet but I dont have Circuit, can you help me please...?
I see that those are two different N channel parts with different
current and voltage ratings.
The 2sk725's voltage and current are quite suitalbe for building
a number of the Zen amplifiers, I think. The ones requiring two
N type Mosfets per channel.
The 727 has a 900 volt rating with a 5 amp current, and I imagine
it could be put to similar use if you like.

The only issue using these for a Citation 12 would be that
the parts are plastic TO-3P, and the originals are TO-3

Hai Mr Pass

Now I am during prepare spare parts of Aleph Power Amplifier
I need 150 Watts rms Power out put.
How many Mosfets per channel ?
How many micro farad of Capacitor?
How many Ampere ( VA ) of Toroid Transformer ?

Agus,
2226G...for jazz😱 I'd personnaly advise 2235 or 2234
they are more commonly used in Hi fi applications...the 2226 is a PA woofer not really for hifi applications ...unless you consider changing the spyder and suspension for softer ones...,
I tried it already...a pass 30w will drive it easily, the problem doesn't lie there...this speaker has a heavy cone, with cone breaks quite high around 1K2, making the mid range a bit hard to cross-over...as well it can be fitted in small volumes, but with low output under 70HZ...

Old thread, I know, but I just ordered large quantity of 2SK725, since they were cheap. To experiment with.
I am building F1 and Aleph J at the moment, besides other line level stuff.
Are there suitable candidates to try 2SK725?
