Something a bit Different

[SQPBC]

:D Hi All, I have a slightly differnt problem i hope someone can help me with. I have an old Yamaha YTA-95 Guitar amplifier. The circut board on the powersupply has had .... well lets say a little overheat problem. What i'm chasing is a wiring diagram for the above amp. Any help would be greatly appreciated.
Thanks :lol:

My searches , so far have come up empty handed.

What you need is a circuit schematic as well as a layout diagram, and enough knowledge of troubleshooting electronic circuits to track the cause.

If you go to a yamaha dealer they may be able to track down a service manual and sell you one.

Try these links, the first you can get manuals etc from Yamaha (not sure about the older stuff tho.)

the second is alt.guitar.amps at google groups, try posting your questions there, most likely somone will have what you need.

Good luck
George
