Marshall tube socket wiring
« on: May 23, 2012, 04:54:07 pm »
Being a nube I thought it would be a simple swap to change tube sockets on this 1992 Marshall 900 Dual Reverb 4500 mod 50W head.
I keep blowing fuses and know there's something wrong. I've researched hundreds of schematics and found the most helpful was a common picture, but still blowing fuses
Any suggestions?

Why did you change the sockets? Was it blowing fuses before you changed sockets?
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!
