Nice job Jim. Thank you.

If it wasnt for your build guide I dont think I could have tackled building my F5TV3 mono amps which sound terrific.

Since you have built most of the F series amps can you describe the sound of the F6? I recall reading that your favorite is the Aleph J?

Can we use the N channel Toshiba 2SK1530 instead of the IRF product? Sound better perhaps?

6L6, another very nice guide from you.

Your guides have made these builds lot easier for guys like me and have most of the questions answered.

Thanks.

An explanation about why you chose 9V Zener could be useful.
Eg If someone is useing lateral mosfets or some other device, then 9V wouldn't really be optimal.

The back panel kit link takes you to ACA. Is this kit still available in the store?

The 9.1v zener is not optimal for any output type.
The BOM could be changed a bit...

With 5.6v zener you get bias range up to 1.5A.
With a 6.2v zener you get bias up to 2A.

Or: Change R7,R8.

In the circuit as it is now, the Z1 and Z2 does absolutely nothing.

The only device I can think of, is some of the new Cree SiC devices.

The guide looks nice but I miss the armory shot. You seem to have abandoned it, but it was great at creating a little suspense. So, I am formalizing my complaint and asking for the return of the armory shot!



Great work Jim!

Lol... I have so much stuff on hand anymore that I just kind of build them as I go along, and rarely have all of it collected in one place.
