cascoded VAS directly driving 3pairs of output mosFETs !
I wonder what the HF load of the mosFETs does to the output impedance of the cascode?

Hi Lineup,
Do you like your 20W version better or this SE version?
What would be a good replacement for the 2SA970/2SC2240?
If you have time, please email me directly. Thanks.
Here's another. I listen to it now really like how it sounds. I seemed capricious in setting up (mean, requires an ideal layout)

Thanks for the link..Can you describe further how it sound? Thanks in advance

Hi,
Jim Strickland's various Amplifiers with either 2SK135/2SJ50 series or the electrically essentially identical 2SK1058/2SJ162. Starting with the Acoustat TNT-120 and TNT-200 and the later Hafler Pro Amp's. I am attaching the TNT-120 for fun. Others can be found on-line.
Ciao T

boyet0173 ,I do not have such a great experience, I just gathered a few amps and more complex and compared with the factory amps but this one I like the fact that (I do not know how to describe a sound) it sounds like it is transparent and accurate bass and as my friend, "he as if he adds the bass "in general is fundamental.
I think that depends on the power supply.
In general, I almost found my ideal sound. As more is written in the link I gave, "that would need to understand this amp is very very very good acoustic system"
Something like this -)

Forget that one and build Juma's modification of Nelson Pass' F5 instead. Same output and topology.
