My take on the SSS Updated: the beast is alive VIDEO(S) NEW
So thanks to Mhartman, Aaron and others, I finally set out to build a SSS based on the 001 and 002 schematics and the layout of mhartman.
I got the faceplates made and am currently sourcing the parts (almost finished) and came up with a PCB layout for the amp.
This will be a SSS sans the Reverb section, but with a Dumbleator instead.
I also sketched up the PCB for the FET with relais on board (sorry no artwork yet).
The power supply will be on an eyeletboard. Power TX will be based on a Twin style with 325V-0-325V 500mA. OT will be a standard Twin.
Here is the PCB layout. I plan on doing this with the toner transfer method. I also plan on putting a labeling on the upper part of the PCB using the toner transfer method.
Would love to hear your feedback on the layout, maybe I missed some things. Chassis will be a standard size ODS chassis with three preamp tubes in the back (where they normally are) and two before the PCB closer to the front of the amp. The layout should fit onto a 201 mm x 79 mm PCB.
Notes:
1. The bias 130k will go to a 10-20k bias pot from the pot back to the second ground plane.
2. The original Master is a trim pot on the PCB "set and forget" going into the Dumbleator. The Dumbleator Return after the second triode will be the overall Master, from there into the PI. The "Return" before the grid of the second triode of the Dumbleator will be the "Return" control on the faceplate.

PS: be aware that the PCB layout might not show correctly if opened with a browser. Should work correctly with Adobe or other pdf viewer.
EDIT:
I uploaded an updated version of the main board. This layout should work. Dimensions of board are 20 cm x 11 cm.
Also attached a FET board layout having the relay on the board. Dimensions 7,7 cm x 4,4cm. Untested since I drew the tracks on the PCB by hand. But should work. Unfortunately .svg formats are not allowed.

Here is a pic of the faceplates with some knobs... Really looking forward to build the amp....

Nice work man. Killer job on the faceplate. Looking forward to seeing the rest. Well done.

Thanks! They came out pretty nice.
Still undecided whether to go for the 70s or the early 80s look

I am partial to the 80s look Either one is nice though.
Re: My take on the SSS Updated: the beast is alive VIDEO(S) NEW
Very Impressive! How did you manufacture the face plates?

Thanks dreric!
I did the artwork in inkscape and then had them laser cut by a shop into two-ply plastic.

Plates look great! I will go for the 80's look
Many thanks for posting the layout for these, as well!
Cannot assess the completeness of the PCB layout though, but looks very nice as an artwork.
I thought about doing PCBs on many occasions and especially for the power supplies, but with two little girls, PCB manufacturing is sort of big no no atm.
I am now rigging for mhartman's layout SSS02 build (having difficulties with the relatively low resolution of the file and some of the values are unreadable, but will compare to the schematic available) and hope to have soon get into the real soldering (made two other amps while at it though - )

Agree. Looks like a great start.Synchu wrote:I am now rigging for mhartman's layout SSS02 build (having difficulties with the relatively low resolution of the file and some of the values are unreadable...
Here's a higher res version of my layout.

Wow! That was fast!
Great and many thanks,

Re: My take on the SSS Updated: the beast is alive VIDEO(S) NEW
Happy to help. BTW, I would recommend moving the HT and bias rectifiers over to the side wall of the amp like Dumble does. There is no good reason to keep them up front close to the control panel.Synchu wrote:Wow! That was fast!

Very nice design with the PCB. That looks like many late nights:)
Are you going to use turrets or drill small holes for the ends? Turrets might be easier if you want to modify otherwise you'd have to de-solder from the otherwise of the board I assume?
For faceplates, for some reason I like the early '80's style with the black background.

Thanks a million ElectronA, you Mhartman, Aaron and all others are very much appreciated by myself and I know by many others here on the board. Thanks for a great PCB layout of the SSS, Chad

Those faceplates look great. I didn't realize there was a layout. You guys have come a long way from the original hand drawn schematics.
It's never too late to have a happy childhood.
Re: My take on the SSS Updated: the beast is alive VIDEO(S) NEW
As an FYI to everyone, my layout isn't true to a particular SSS. It has elements of both #4 and #2, but it isn't an exact take on a particular Dumble. It is one that I built a while back and enjoy before selling it off. Aaron has done a nice layouts for both SSS02 and SSS01.
