Silver Jubilee
« on: June 07, 2012, 07:13:09 am »
 Hi

My brother has heard my amps and he want's me to build him a Silver Jubilee. Any tips/advice on the SJ? I've been looking but can't find a layout, any have one or have a good site where I may find one. Any advice is greatly welcome.

 Thanks
   Jeff

Here's a good starting point complete with schematics. No layout though.

EDIT... Here's a layout...

A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Hi Jeff, Ceriatone does a couple of versions that look good. Loosechange did a SE one as well.

Anyone know what specs I need for the transformers? I got the schematics but no voltages.

Hey jeff, This is what i did and the 300-0-300 transformer was one i had, don't know the exact one marshall used. The relay circuit caused me some grief with a buzz but the 51r resistor did the job to reduce it. Good luck
