For Sale FirstWatt F6 original prototype

Offered here, for your consideration, an original prototype FirstWatt F6. Built and sold at auction in support of Burning Amp by Papa in 2023.

This amp is of the original design configuration that used SemiSouth JFETs, not the MOSFETs that the commercial F6 used. Note the dual LEDs on the front. I have no proof but I believe Papa assembled this himself. The amp was opened and pictures taken at BA that year, I have not opened it nor messed with it or put it on any test gear, but I have listened to it lots in my main system. There is nothing at all wrong with this amp. To my ears, and in my system, it is the most detailed amp I have heard, but for some mysterious reason I favor the air and liveliness of my F5m and Aleph Jzm more.

I paid $2600. I am asking $2600, plus shipping to your locale (it will come in the factory original shipping box). If you happen to reside in Northern California, I'm open to arranging a pickup but please be patient with me as I work for a living and have some travel coming up. This isn't about the money, it's not a forced sale, I'm not in a hurry, no low ballers, I know what I've got, etc., etc. I've just listened to this amp enough to learn from it and I'm willing to pass (haha! Pass) it on to another aficionado.

Thanks for looking.

This is truly a special and rare amplifier! I was kicking myself for not bidding on it at BA23, but luckily another SemiSouth F6 was auctioned at BA24 and I was fortunate enough to win that. If I didn’t already have one, I would have jumped at the chance to buy your amp. Good luck with the sale!

I have the one from BA22 and have to say that it changed my mind about not wanting to build an F6 so now I have 2 diy F6s. One built by me and another built by Papa. I hope someone here can give yours a new home as it would be a terrible shame for it to wander into obscurity like a few of the pilot run F7s seem to have.

It's going into a black hole, trust me.

Some people NEVER sell.... they take it to their graves.

Maybe need a bigger pyramid?

Holly Crp..! This looks like my bedroom. Except there is no papa Pass under the glass (yet)
$600 for one power transistor?? It's more than WE 300B
 
Actually, that's an old picture, Queen Cleopatra brought more gifts..

You ought to see my home office.

The main bedroom system is actually quite restrained... a big Marantz 2325, ADS L810s, a Samsung tablet and a USB DAC. The TV is not hooked up to it... yet...

Oh wait, I sure hope Nelson doesn't see the comment:

" there is no papa Pass under the glass" 😡 😡 😉 😛

I meant that for me, not for Nelson. Yikes, are you calling us old?

This was the star of the show at the BAF '23 fundraiser...

A few hours before the auction, there was a moment when we were setting things up, making the display table for the auction items where we thought it would be fun to remove the lids and show them off, and when this particular F6 was opened there was a bit of a shock and awe as the SemiSouth transistors were staring up at us...
