If (ONLY) G600 agrees, he should reduce his subscription to 1 pair before you can fit it.

Patrick

spades · 2019-10-03 9:26 pm

It appears from the list that g600s pair has been taken by somebody else Iam assuming with his permission.If no quads available could you fit me in for two matched pairs.If this cannot happen may i be considered for any future group buy for these fets. my thanks regardless .Regards spades

Would love a pair if one becomes available...

Hi Patrick

Can you increase me to 2 pairs, now that Luke pulled out?

thanks
JimS

G600 · 2019-10-15 5:31 pm

I'm afraid that Patrick has already taken care of mlwebb on Luke's position...

Further to our GB for Semisouth JFETs for possible Pass J2 DIY clones, we are happy to offer also a limited amount of 2SK3497 quads and pairs.
These can be used to replace the Semisouth's for the SRPP current source.
Patrick

Is the SRPP current source transistor the transistor at the "top" in J2 output stage?

The other still has to be a JFET?

The term "SRPP" …..PP stands for Push Pull? …..but J2 is single ended?
Just try to learn some new stuff

JeffYoung · 2019-10-16 12:02 pm

Yes, the CCS device is the top one, and the bottom one must be a JFET (at least to be a "J2").

In a "true" single ended topology the CCS provides a fixed constant current. In between that and a "true" push-pull are topologies that modulate the CCS to a certain extent to follow the output device.

Some names for these include SRPP (series or shunt regulated push-pull), SEPP (singled ended push-pull), mu follower, and Aleph (a Pass patented design, but not used in the J2).

gary s · 2019-10-17 10:04 pm

Hi Patrick, are you still looking at end of November for shipping on this group buy - any further updates an testing and when you will call for payments?
