I need a schematic for a 1966 PA 4100. It is a 100 watt 4 channel solid state with 2 cabinets (4x 10 in each). This is the PA the Beatles used in the let it Be Sessions...and also on the roof top! The speakers are fine, have head in shop and tech needs schematic....anyone?

Try contacting Fender Consumer Relations to request a schematic for this vintage unit directly from Fender.

If you email them they'll get back to you pretty quickly with a printable PDF file if they have one.

I tried fender first...they do not have many of the pre cbs schematics...also tried many vintage fender repairs guys online...most say they have only see pictures...if you look at pictures of the Let it Be sessions, the Beatles used this in studio and on the roof top...

thanks for the info though..Anyone else??

Actually that is a CBS schematic since CBS took over in '65. I'm not surprised they don't have a 46 year old schematic though. I've looked at my usual sources for PDF schematics and no luck.

I knew a tech who could fix about anything without a schematic. He died this year though. I need a new tech.
