...of some of the new EC amps being made.

I thought it might start a discussion, and maybe I'll learn something from it.

   Bird , Thanks for the tour !!!   The only thing I was sad about was they didn’t actually test the amp with a guitar ...  Shocked    A guitar amp is not a Hi Fi amp ...  so they won’t actually know if it’s really going to sound good on a guitar ...   Just playing a little music through it at a low volume only proves it basically works ...   I wonder if Eric would approve of that  with his name on it and all ...  Huh   

  Love those amp assembly gloves  Rawk1 .... I just gotta get some of those ...   Just finished a similar build and my fingers are all scratched up from metal bits and  cut off leads ... Facepalm

I actually googled them. I'm not sure which model/materials they are using. I've been using cheap, latex on knit gloves from Walmart for ages. I once heard someone refer to them as "Spiderman gloves".


What does the added bias pot actually do?

It allows re-biasing for new tubes (without having to go to an amp tech)
here's the silly part: the  tweed champ is a cathode bias amp, it self-biases anyhow. 
So, this new product either A) is not the original tweed circuit, or B) has a feature that is useless.

Also, at 4:21 in the video you can see that a lot of the connections are not soldered but use clip connectors.  They should've gone the whole nine yards and just done the last dozen solder connections properly.  It's like the whole 'hand wired' thing is for show, if you cut corners like that.  why make a point of having a 'hand wired board' if the connections to the front panel are inferior?

I wonder how much this EC endorsement product will cost?   I bet it will cost more than if you just went out and found yourself an old tweed champ!

 OMG  !!!   I just saw the prices ...   Shocked Shocked Shocked  They gotta’ be kidding Huh

 BT, I’m also at a loss to think what they’re doing with that pot ...   If they’re using it to slightly adjust the cathode bias resistor on the Champ , it’s not gonna’ last long ... and I cant see any advantage of changing to a fixed bias on a single ended amp , which sorta’ throws the whole thing off and adds more expense and complexity Facepalm ... SE amps being always biased hot (near the max ~90%) for class A operation ...   Huh

  I still think the expensive bit is the EC endorsement , which, as you can see, is a most effective marketing tool ...  Tongue
