Re: Dumbleland Special 150w ser#009 Schematic
A clearer photo of the stamped codes on the output transformer could potentially help with identifying the details. There are tons but obviously not a single one made it into the post :o Ill fix it right away. Thanks for noticing! :D First I too want to thank you for the work you put into this and ...

Re: Creating the 30 deg angle for a Fender princton Rev chassis
I don't use any sites like Imagur, I upload directly to the site. When I post pictures here I go to the bottom, under the "SAVE DRAFT", "PREVIEW" and "SUBMIT" buttons. There are two tabs, "OPTIONS", and "ATTACHMENTS". Select "ATTACHMENTS". Click "ADD FILES", then select the photos you wish to upload...

Re: Dumble 102 - Finished Amp pics
Great looking amp!
First time I've seen this embossed pattern on a covering. Is it Tolex?

Re: Dumble SSS with Eyelet Boards
Fusion 360 has a free license for hobbiests, just limited on number of jobs that can be saved. I let mine lapse (requires annual free renual). Last time I looked it was a bit difficult to find, but it was there.

Re: Building Power Supplies for 2 X 12ax7 pedals
Check out the power supply that C2C Electronics uses for their PCB pedals. Cool, thanks! They look to be sold out, but they have the schematic and parts list which is handy. Just found this other one, but you don't get any info about it till after you by it: https://frogpedals.com/index.php/product...

Re: My SSS is too clean for me. Ideas? Add the FET input?
I'm not familiar with the MHartman layout so this may or may not apply: my SSS is based on s/n 002, which uses a 5751 for V1. Would a 12ax7 here wake it up? The FET definitely makes a difference! I can't recall which JFET I use, but I found several threads here on TAG discussing a few different opti...

Re: what is the purpose of the anode resistor on output tubes
Couldn't it also be used to determine true output power for the tube, unlike the cathode 1 ohm resistor which is combined anode and grid/screen currents?
Care would need to be taken with the measurement as it is at B+.

Re: JHS versus Aion pedal kits.
I've built several pedals using pcb's from PedalPCB. They just supply the boad and documentation, you have to source everything else so it's basically a scratch build where you get to choose the quality of components that go into it. That site has an EXCELLENT forum for pedal building.

Re: 1908 Washburn tuners
Can the gear be removed?
That's a very small part to weld.
My first thought for it is maybe, depending on base metal, a silversmith or jeweler could silver solder it.

Re: Speaker swapping to increase volume
My experience: I have a Crate Stealth GT50 1x12 combo amp (4x6V6). My son was using it a few years ago (before I built him a Dumble style 100watt). He complained he couldn't hear it over the drummer in his garage band at the time. I replaced the stock speaker (no idea what it was) with a WGS G12C/S,...

Not CTS, but I've used these Piher with good luck. Mouser has both vertical and horizontal available.

Re: Trinity Amps
I went through the same thing a few years ago. Finally got my money back after several months through PayPal. I had a thread in their forum, think it's the same username I use here. I had paid for their Dumble style amp. All around very frustrating bad experience. From my understanding the guy that ...

Re: Guess this mod!
The area around the el84 sockets was a bit toasty and I cleaned them up a bit. In the process, there have been a spot or two where copper trace can be seen leading off the tube terminal. Not sure if that is a big deal or not, if so, what is common practice for addressing that? From the first pictur...
