Good that is what i have. I also have some 2sj162/2sk1058, but they are laterals and dont think they would be a good drop in. Generg, If you like BA-3, take a look at Juma's version of F5 preamp in post #42 of his thread. Accuracy of the F5 coupled to sweet F4.

It will be interesting to see if Nelson maintains the no feedback approach with balanced version of BA-3. Don't have all the stuff to finish BA-3 FE, so I will have to wait until next week.

O.k., I am a bit tired to build amps at the moment, in the last two years I started with F5, the complete FW series, Burning Amp series, many Alephs, J2 clones, M2 transformer clones......... After some time you loose impression what is better or worse and I accustomed to many sounds....
Now i have to relax a bit....... Und I just enjoy the new toy to measure distortion with all the parts in the basement...

yep, M2 uses fairchilds, and I think one of the reviews of the PASS LABS product showed them too.
Where can one get these fets?

I am sure he will do!
After many futile tries to get them, I found this site From Mike
Garage Sale - Audiohobby.com
And he was so friendly to sell them overseas to me....
I will match them and have a try.

When I get them I can send you some, but first I must match!
Sold out! Yes, I was the culprit! I suppose!?
Let me know how you measure -
I can use the same measurements, and if there any singles, we might be able to make a few extra pair - or hock them to F5 builders.
Hi tea-bag,
I think you have really more experienced, PM me your values and I will try to follow you!
I suppose we had the same gracious source, had we?
Probably so.
it depends on what target we want to the fet at.
Probably 20-24v with a 10R resistor (probably need 50Watt one)
Just tap of the positive reg of a Pass supply, with a channel not hooked up.
