F1 Build
I have been working on this F1 amp for the last several months. It was a really fun project and it pairs well with my Foxtex FE206En based speakers. The reviews that say the F1 has more bass than the F2 are accurate, I had to move the speakers further out from the wall cut back a bit on the bass. It is also smoother and clearer than my F2J, even as a straight up F1 without the Jfet output transistors. As always thanks to Papa for sharing the design and to everyone else whose input/suggestions helped me along on this project!

Yes I did have to google that😀. Thank you very much, I really admire your projects as well!
Wow, that's beautiful! I love the laminated faceplate. And great job fitting all that inside! I had challenges making clean layout in a 4U with only one transformer and PSU!
Way back at post #4399 I posted my first DIY amp build, an F6. It was largely a paint-by-numbers affair, constructed by following 6L6s excellent build guide and aided by all the contributions in the massive thread that it spawned.
Today, largely thanks to the information found here at diyAudio, I've just completed another First Watt amp - the Aleph J - with a semi-custom CLC power supply.
So, another thanks to all of you, and of course to Nelson Pass.

Did you get a chance to compare the sound before the 195G10, and after?? What are your impressions?
I enjoyed your Imgur build album - very nice. The amp looks great, well done!

Fully Articulated,
Amazing attention to detail and very well executed! Take a bow...
Hope you are going to put a cover with a see through window on this.
Also very well documented, thank you for sharing the build pics.
How are you liking the sound of the amplifier? If you don't mid can you share a few more details about your setup?

Thanks Nick for your comment (and your help).
The original idea was just to try building a CLC supply to replace the standard CRC one in my F6, and hopefully learn something in the process. At some point it transformed into an entirely new build, so I doubt I'll be able to do a LC/RC comparison.

Cheers zman! I'm considering a see-through top for the future perhaps.
I've only used the amp with test speakers so far. Hopefully I'll get some time to listen properly over the weekend.
The Aleph J will be feed by my previous project, an Aikido preamp and an ANK DAC, if that's what you mean by setup. The amp will be powering Paradigm speakers, but maybe one day I'll try DIYing them too - if I can find a willing carpenter.
If you can make such beautiful amps, you will have no trouble to make a simple wooden box -- go for it!
