Unfortunately I don’t. Can’t really find any info on these transformers, only thing I can find is the schematic for the Deuce which shows a fwb. And you have the colors of the secondary wirings. The fwb is for the B+, The secondaries with 1 diode is the bias circuit. You can use the standard ods bi...

Hi Jim, I got a Precision filter board available. Pm me if you can't get it locallly.
Best ,

Thank you for posting these! I've never had PCBs made before. Is there a company anyone would recommend? Matt J. JLCPCB, PCBWAY, PCBWAVE. Local is also worth to check out but keep in mind that most small companies have them done in China anyway and are very expensive. I had good experience with JLC...

Ryan added the pcb gerbers to his github project. Here you can find all ins and outs of this project.

For anyone who desires to have a SSS002 chassis and pcb made by a manufacturer: here are the files.
These files will also be available at Ryan Colgan's SSS002 github very soon.

FYI, They Ship from the N.E. US, Chassis are $150 PCB Sets are $95. Mike Hi Mike, you mean by "they" yourself? You bought a few sets from me and have them copied and now selling them? You could at least be honest. Fwiw the original designs will be open source soon so anyone can order the pcb by a m...

Well it had to happen one day, the copy gets copied. Even my flaws are copied lol. Maybe Ill make the pcb designs avaialble for anyone. Keep an eye on Ryan Colgans Github.

In the garage talk is also a thread. Yesterday around 7000 "guests". Looking almost like a ddos attack.

There are a unusual amount of "guests" on this forum:
Around 1800 right now and yesterday there were over 2500 "guests".

Hi Tony,

At the time #102 was revealed one of the actual insider said: "Resistor feeding from the .005 OD2 cap is 150K and not 180K".
Also Brandon from Bludotone: "100K Feeding Drive pot, 150K feeding Ratio Pot"
Is this your personal observation or from someone who has been there?

Erwin

Fwiw #102 has both Plate and screen set up as precision (or totem style) for the power tubes. The last filter section is a can cap like #124. Anything that's on the B+ line has influence on the sound. Why members specifically have bad experiences with F&T is interesting. What has set them apart ,con...

easier to change a bad relay.

I never had a bad relay, I have had bad sockets after multiple in/out while testing.

No, I'm too busy with work. Although I do have 3 chassis with faceplates and 4 pre amp holes and fitting pcb sets.

Amp had been on maybe 4 or 5 hours after being built. I will have the amp home tonight. We just tried to use it here now and same thing crackle sound in both channels.. we unplugged effects loop and pedal board, different guitar cables. Same issue. It did sound amazing though when working. He was p...

For a Dumblelator 1/16" (2mm) is more than suitable. Those Dumblelator boards are small compared to a full size ods board. If you are worried about flimsy boards with 1/16": add a mounting point where you think the board will flex or put a extra insulator board(same size underneath. Fwiw I used 1.5m...
