Re: Can We Discuss Major Pigs?
The Sound City 50Plus MkIV took that tone control idea a step further, adding a mid control. I don’t regard them as being active tone controls, but I’ve been overruled on the matter by the super brains on MEF :shock: http://soundcitysite.com/Sound_City_LB_50_Plus_(11-73)_Schematic.pdf To bad the sc...

Re: Vibrolux Reverb AA864 schematic
Vibrolux AA864 circuit. It is not just an AA964 with Jensens or Oxford or Utah Coil or whatever "different" speakers. I just had a 1965 in and it has a higher voltage preamp rail. Fender was NOT overly diligent about gluing in the proper tube charts either so you may or may not have an AA964 with a...
