Hi Jeff,

I believe your understanding is correct.

Cheers,

The 1N4001 has a much lower reverse voltage, but I don't see that, that serves any useful purpose in this location.

I ended up making a few changes to the coupling cap arrangement (2 x 8,200uF electrolytics and 1 x 8.2uF polypropylene "jelly roll"), and added a bypass (10uF polyester) to C7. My PSU is also a bit different with 36V secondaries and dual mono construction. So I don't think "clone" really fits anymore.

I thought about "DIY F3", but I'm also trying to capture the aesthetic of the Firstwatt production units, and DIY doesn't suggest that to me.

How about:

think Jazz standards

whatever you do , name of the song is there , same as author(s)

DIY doesn't need to be pejorative (of lesser quality) .... it simply means not made in series , when quality is there

I didn't mean DIY as pejorative. Rather to me it conveys a custom implementation, not just a non-series implementation. Sort of like doing a cover song, but as yourself.

Whereas I'm (shamelessly) copying the form-factor of the production implementation as well. More like doing a cover song dressed up as the original act. Which led me to "tribute act".

Cheers,
Jeff.
