Build #1 was the Denim Deluxe 1x12 combo, it used a prototyping board;

I'm midway through build #2, the Blues Briefcase 1x10 combo, it uses the TubeDepot 5E3+ PCB;

I just designed my Turretboard for Build #3, the Hellhound 1x12 combo.

This is a DIYLC file I submitted to Doug Hoffman for drilling on his CNC machine, it's about $18 with turrets installed. It's a 9.5" x 3.125" board with 35 turrets; you could also make it with eyelets instead with this same template.

If anyone uses DIYLC and would like a copy of my board file, just DM me and I'll be happy to share it freely.

Why don't you make the board yourself? Drilling/installing turrets isn't that hard. Especially if you made a template for drilling.

I think I will next; but Hoffman makes it so easy and cheap to just send him the file, I sent him the custom layout last night at 1:30am and he shipped the completed board to me at 8:30am! It was seventeen dollars and change, seemed very reasonable.

It's definitely reasonable. Post some photos after you get it.

Sure will Josh, thanks. I was originally planning to buy the board and turrets and then do all the drilling and swaging on my drill press, but then I saw how incredibly cheap it was to just have Hoffman fab it for me; here is the cost breakout:

Board material: $7.13
35 turret lugs: $5.35
Labor - Drill 35 holes: $2.80
Labor -Install 35 turrets: $2.45
Shipping First Class USPS: $5.22

The total labor is about the cost of a Starbucks cold brew. I think I would have been stupid not to have him do it (other than, I'm sure it's enjoyable and satisfying to do it myself).

Will post some pic when it arrives and when I install the passives on it.

The Hoffman board arrived, here it is next to my current Fullerwell build for the blues briefcase. Solid 1/8" thick board.

The good folks at Wattkins kindly added the Fullerwell (Denim Deluxe version) to their menu for the Universal PCB (available at Tubeface); it's the 12th schematic in https://drive.google.com/file/d/1ApurBu ... p=drivesdk

I'd say that is quite an improvement over my hand-drawn original!

I don't shop there, but the page is confusing; it's hard to tell if that includes components or not. It might?

That's just for the board with turrets installed. Could get 3 custom turret boards from Hoffman for that price.
Loaded with components, the Trinity 18 board is $120.

Weber Turretboard: $19 https://www.tedweber.com/6m18fb

Over at Wattkins, jamesrr has kindly worked up the layout for the Fullerwell (Denim Deluxe version), it's the 7th page in https://drive.google.com/file/d/1PuCY0M ... j87Ld/view .

So, along with his schematic, that would be a good way to build one on the Universal PCB.
I'm going to give that a try for build #4. The PCB is available at Tubeface.

I'm very grateful to jamesrr for his great work.

Here is my detailed view of how to build the Fullerwell circuit on the Wattkins Universal PCB; this version has an off-board chassis mounted EZ81 (not shown here).

Looks like you could do a SS rectifier on there too.

Yes that board is very flexible! It also accommodates cathodyne (as here), paraphase or LTP PIs and cathode bias (as here) or fixed bias. 1 channel or 2 channels, octal or noval tubes, etc...
