We only traffic in information. We are using the Caymans

Sweet!
I was just starting to put together a parts list for the v1 Pearl.
But I can wait...

Question: what are the main differences between v1 and v2?

Question 2: can the 2SK389 be replaced with 2 matched 2SK170s?

I think you can but you should mount them "face to face" because of the thermic stability.

You don't even need to match them as they run in parallel (just like the K170-quad at the input) and not in a differential pair.

Also the quad at the input is not matched in the original article as you see from the different voltages across the source resistors - matching also not necessary or helpfull.

Have fun, Hannes
