Gibson G 30 schematic issue
« on: March 21, 2011, 01:27:55 pm »
Greetings.  I have a G 30 sand amp which snuck into my truck at a store I do work for.  They thought it was a GA.  I pulled up several schematics for the thing but none have values on the components escept for the SS devices.  Cap,diode, and resistor values are not given.  I've had it too long not to fix it, if you get my drift.
Thanks,
Larry :BangHead: Feels so good when I stop...

For a qualified amplifier technician the amps on this area are almost the same. They used all similar schematic.
Somme difference in value of capacitor or resistor but easy to find for a tech.

Used a Gibson schematic wich the same tubes a follow the value you see.

This "sand amp" has no tubes.
