Is he trying to sell you something? NO. Is he trying to convince you of something? NO.
He was first to built the amp, said he loved it. He pointed out that there is an issue with the voltages and tried a few transformer sets and tweaks to work it out. His amps tweak into something else. He knows how to build, He likes his amps a lot. He's generous enough to share his process, now he get personal attacks?
What exactly are you expecting him to do for you?

Am I missing something? I have zero authority around here (I'm just a hobby builder trying to learn form this community), but I don't see what the big deal is. It seems like there is enough information here to point you in the right direction for 67plexi's tweaks and I for one am grateful for what has been shared by him and by Charlie Wilson.
Now, the more info the better so I would love a more detailed description of changes since I have a 5e3 that I would like to take in this direction.
It is not a question of credibility regarding 67plexi's abilities or his statements about his amps. He is quite an experienced builder and has historically posted about many of his builds.
For me it is a question of sharing and this is not the first time or the first thread for which this issue has been raised. Is it good form to take information graciously and idealistically provided by a member, Charlie in this case, and not give anything back? It is made even worse by all the bragging about how good the amp sounds. All the 'details' regarding transformers effect on the sound. Then turning on a dime and stating, oh and BTW, I made changes that I won't feed the trolls. Sorry, but that's some fucked up, insulting and narcissistic shit right there.
Vibratoking, nobody owes you anything here. Why this behavior? Is there something else going on that I do not know about? Because I do not see the basis for the tone of the posts. Please elaborate.

We all have voiced our complaints over the share, don't share, hoard info, don't hoard info, the forum used to be better, Nik screwed everything up, pro builders don't share anymore, it sucks bla bla bla.
I need all the help I can get to make an amp so, I agree with you I wish everyone shared everything in minute detail. But the truth is no one owes anyone anything. Plexi shared more than enough info to copy his amps and there is plenty of into to build Charlie Wilson's amp, I did.
I don't think personal insults are appropriate.

I was also confused way back about what was being stated about how good the amp was sounding because it didn't reflex what I was hearing from my own build using Charlie's layout and notes.
The Tweedle Dee amp is better then a stock 5E3 in my opinion but don't expect some magical bloom, note flipping or your bell bottoms flapping in the wind.
Glad I built it and probably will build one for my friend to have. I do have a 35w Fender OT that I plan to try build another Tweedle Dee using different PT as well just to see if I can find anymore magic. Plus I took notes from all the builders and also researching about grid blocker values with this PI because 100R seems way to low but if your not getting distortion then the 1m value can be backed down. Why not just use another trimmer here.
Mark, thanks for the honest opinion on your build. I respect your input. I think your post will help some guys make a more sound decision about whether or not to build this amp. It doesn't help anyone to build a nickel while expecting a dime.
I'm going to play with that 3m3 resistor as well to lower the NFB when lowering the grid blocker 1m to say 470k or so maybe two more trimmers are needed.

I agree with Mark on this one..I compared the Tweedle whatever amp Charlie posted along with an original 5E3 and although I preferred the Charlie amp a bit better (a bit tighter and slightly bigger sounding as well as a bit smoother) It wasn't by any means a HOLY shit had to build myself one moment..(Not much of a small tweed amp kind of guy I guess) It was cool but really IMO NO BIG DEAL!!...Sorry for the let down...YMMV!!!!
I Prefer my 49 5C5 Pro!!

First and foremost....I have zero expectations from anybody here. I study the greatly appreciated information I obtain here and share at the maximum level that I am capable of....gladly!!! I attempt to do so in the most respectful and objective manner possible which I hope my numerous posts demonstrate.
Secondly....I couldn't be more sincere in saying that I am happy that this turned into a great sounding amp. Really! Good on you Steve!!
However, I am extremely disappointed by the fact that the qualitative judgements provided here flip-flop all over the place regarding how the amp sounds.
Read through it carefully and try to figure out whether or not the original plan is "good" or "not good". Sure...that is a subjective judgement and we all know this and filter it accordingly. That is an understandable shortcoming in this hobby and the majority of those that participate here accept that like I do.
Simply put, the thread starts out with the Wilson layout being the best tone generator in the world (after fixing an error or two) and then ends with it wasn't all that good in the first place.
To find out only at the end that it has been morphing into something different all along is frustrating to say the least. And..if all this couldn't be considered uncredible information...I don't know what would.
Is it the end of the world...of course not! Truth be told...I bought in by acquiring a couple of the Schumachers (sp) cited as being a key element in the amps glory so I could try a couple myself. I think that like many here, I have a love-hate relationship with small Tweeds and would jump at the chance at increasing the love. The fact so many have jumped in to try one supports that thought.
Finally, please read my previous point carefully. I wasn't casting dispersions on Steve....only the information provided in the thread. I am sorry that some people are so quick to jump to the assumption that I was attacking him personally in some why. But...that is their problem....not mine.
Could I have been more sensitive in my wording....absolutely...and for that I apologize.
But..come on...really?!?! You can correct me if I am wrong...but...I don't think that I have ever come off as being inclined to lodge personal attacks against anyone.
Mark, I understand your frustration I built #1 off of the photos. Then the hand drawn layout was released. My error is in the PI and it's a great error this is why I could not copy #1 in #2 build
#2 sounded like just any other amp nothing special. But #1 sounds like a room full of Marshall's on
volume 2, So on #1 pin 7 pin8 are backwards and the 4k7 was adjusted by the 10k trimmer
so I ran a jumper 4k7 to 1meg on the PI.
Steve.

I think the problem is in the PI of the Tweedle Dee the .1uf/600v coupling cap should not be connected to the 10k trimmer wiper the cap should go to pin 8 and the other .1uf/600v cap should go to pin 7
The trimmer just sets the balance between 110K on one side of the PI and the 89K of the other half. Don't need the PI to be symmetric for guitar amp or completely balanced.
Alternate connection would be after the bias resistor (4k7) and use the trimmer strictly to increase resistance to the cathode side from 89k fixed resistance to 100k with trimmer.
