Yes, that's right.

Teabag's stuff is all on one single board, so you can make a monobloc, but it's going to be all on one heatsink. That's fine for me, since I would build a different profile than the standard chassis with the left right heatsink set up.

It my opinion that this is not as efficient in terms of utilizing the heatsink as it might be. Vertical is how I am going, myself. Of course that yields a different shape amp, and isn't going on a rack so well, but I don't like racks/shelves that much, and never put my amps on them anyhow...

_-_-

eitherway, I'll tell my friend to wait a bit, and hope the Cviller boards come up again...

Bear i have the full Cviller boards and all matched fets for a 2pr setup, purchased a few years ago when it was offered , doubt i will ever use , let me know if interested , i may part with it, i really dont see myself having speakers where i can use an F5c.

Regards ...

Default Provisions for JFET degeneration

Does F-5T boards have specific provisions for the use of extra degeneration resistor for the 2SJ74 to make it track better the 2SK170 (the EUVL trick used for the F5X)?
Or is this tweak completely redundant after Mr. Pass introduced the P3 potentiometer?

It has a pot across the source resistors that allows for trimming the values.

Folks:

Does anyone know the lead spacing on C1 (the anti-oscillation cap)? I'm putting a Mouser BOM together and was thinking of using a .001 uF Wima cap (http://za.mouser.com/ProductDetail/W...50D8XPE6KuY%3d) with 5mm spacing.

If this isn't a good option, your recommendation would be appreciated.

Regards,
Scott

So, you need to buy two sets of boards, which gives you a redundant FE board, correct?

Folks:

Could someone post a BOM for the latest generation of the Store's F5T boards? It appears that there are parts ID inconsistencies between NP's schematic and the Store's boards and I lack the expertise to confirm what goes where.

Much appreciated,
Scott

The silkscreen numbering on the newest boards should match the F5Tv3 schematic.
