Default Which first watt amp for Zu Druid mk4?

Hi all, I have a pair of Zu druids and am looking to buy a first watt amp to drive them..Anyone have any recommendations as to which one to go for? I was thinking of a F1 or F2 but keen for other thoughts.
thanks!
Boyd

A friend of mine is driving them with F4's, driven in turn by some
300B SET amps. He seemed very happy until he heard the latest
upcoming design.

Does this infer that I would be wise to leave the task of building your F5 until a later date? Or is that latest upcoming design not to be for DIY?

No, build the F5--it is a great amp. Just build a really nice chasis in case you want to swap out amp boards in the future.

I am assuming that Nelson doesn't spend his time working on a newer, but crummy sounding design. So, if you wait for the next great release, you will never build an amp until Nelson retires.

This is very true to many a Pass DIY'er.

What is interesting, is that you frequently see people go back to the older NP designs, to pick ideas for whatever they decide to build.

I once built a stock Zen, using the official boards and all, but since then I have seen the designs as an education/inspiration.


But it all has a scent of where I find my inspiration

So, really just go pick whatever you find useful from the designs, mix and match, and see where it takes you.

I do it quite often, but I keep them in the attic.

I was just going to buy as many 2SJ74BLs as I could. Yes, there are plenty of import problems to face. Sometimes they go off smoothly, sometimes one may even have to forfeit the parts.

So my question to Nelson is, does the new upcoming design use this specific and fast depleting P-channel JFET or should I just buy a few for building the F5?

I'll understand if Nelson chooses not to comment on the upcoming design this early.

Thanks.

I recommend that, but most of the things I'm working on can be done
with 2SK170's also.

Nelson, you are certainly the One and Only One.

This is both good news and great news - in one go.

Thanks,
