Tweedle Dee Deluxe and Tweedle Dee Champ
Big thank you to Charlie Wilson for uploading the pics and providing all of the useful info on these amps. Also, big thank you to the TAG community for all of the input, ideas and collaboration. Here are the layouts that I did (with much help) based on all of that info.
Maybe someday someone will upload some clips!

Rectifier chart.
This is only a guide since tubes can vary so much.
Always measure voltages for actual voltage drop.

Here is a nice spread sheet for Magnetic Components.
It shows all their power transformers, Output, Choke and others.

Re: Tweedle Dee Deluxe and Tweedle Dee Champ
In the Tweedle Dee Champ layout the cathode for the power tube doesn't show a ground... am I missing something?

Re: Tweedle Dee Deluxe and Tweedle Dee Champ
Yes, it's hidden in plain sight, notice how the eyelet is filled in dark. That's the notation that it's a ground point.Randy Magee wrote:In the Tweedle Dee Champ layout the cathode for the power tube doesn't show a ground... am I missing something?

Minor point, but...
The schematic says, "Based On The 5C3 Deluxe"
I think the person who drew it meant to say it was based on the 5E3....

Nice layout very clear
Has anyone come with a good way to set the PI balance pot?

What software do you use for the layout?

Re: Tweedle Dee Deluxe and Tweedle Dee Champ
Nope, the schematic is correct in notating a 5C3. The actual tweed amp posted and documented was a modded 5C3, notice it only has 3 inputs.tictac wrote:Minor point, but...

Look at the 5C3 schematic and tell me what part of it resembles the Tweedle-D. The actual amp may have been a 5C3 at one time but the Tweedle-D is way closer to a modified 5E3 circuit... The volume and tone control of 5E3 and 5C3 are simliar and you've got a cathode biased pair of 6V6's but that's where the similarities end.
You've got a grid leak biased 6SC7 and a 6SC7 paraphase PI in the 5C3.
The Tweedle-D sure doesn't look like a 5C3 to me but if you want to call it
that then it's a free country. I thought contributes around here were super sensitive about being accurate and I was just pointing out a minor inaccuracy.

Re: Tweedle Dee Deluxe and Tweedle Dee Champ
5D3 had 3 inputs, and noval preamp tubes, but it used a self-balancing paraphase inverter. That is closer, but it is possible that the donor amp was some kind of transitional model between 5D3 and 5E3.

Re: Tweedle Dee Deluxe and Tweedle Dee Champ
Hello, the original amp was a 5C3. When my friend brought the amp to Dumble it was never specified that it had to be a 5E3. The only parts of the original amp left are the cabinet, chassis, transformers, and one red crayon cap(the board was replaced). Tube adaptors were used for the 12ax7 tubes. Yes Tictac the caption probably should read modified 5E3 circuit built into 5C3 amp but I appreciate the effort that went into doing the schematic(thanks Ultrahookedonphonix) so did not see a need to get to picky about it.
