Got my amp build completed. Very happy with the build. I am especially proud of the fact that I built my own cabinet and people who have seen it think that I bought the cab. I have to show them the pics of it in the process of the build to convince them.
I have had some cabinet rattles/buzzes since I completed it. They were not there when I trial fitted it and tested it prior to putting the tweed and grille cloth on. I guess the wood clamps down perfectly and flush when bare. The tweed probably would not be so bad without the polyurethane on it. I have used some foam and felt pads to get rid of the rattles. I am not surprised by this, I had to do the same to my Mesa Boogie which I paid over 2 grand for.
Today I went in and changed some cap values. Had a little bit of farty bass on the normal input with a les paul with humbuckers if really cranking it, especially on the neck pick up. I also did a volume control mod to make them independent of each other. So far I am super happy with that mod but I need to pickup a dual pot for the tone control to finish it out. I will say though that the tradeoff of getting rid of the farty bass is that the bright input 1 is really bright now when on the bridge pickup.
All and all I am not convinced that the Mojo American Vintage speaker is the real deal. Per the rep I talked to it is made for them by Weber and is an improved design of the Weber vintage series. It is great at clean sounds but I think it is kind of fizzy when it goes into break up.
Next step is to bump up the preamp voltages a bit. The transformer I have is a Mojo/Heyboer which accounts for the 120V mains we are on today and keeps the output @330-0-330. In the end I end up with 338V at the plates of the 6V6's which is lower than a lot of 5E3's run but when I refer to data sheets and measure and calculate my plate dissipation I cannot really see where running higher voltages is in my best interest. Maybe I am missing something here. What I do know though is that my preamp and phase inverter can very safely handle higher voltages. I played with bumping them up and the amp seemed to really like it. Just have to make this change permanent now.
