Default high power output instrument amp

i am considering building a few amplfiers, one to amplify my electronic drum kit, because of the wide frequency range required i cannot use a guitar amp, and am considering basing it uppon a hi-fi amp of around 100W

there are many amps on the internet that are this power, but i would like a relativly easy amp to build so require either a very basic circuit to use or a pcb layout already made.

and no - im not using a chip for this amp - it takes the fun out of it - i will consider both ss or valve

Hello fez,

Have you finished your project yet? I have a design that I am working on that may be of interest to you. Check out the following link and look for the zip file:
.200 Watt Lateral Mosfet Amplifier and irfp240/9240 (segue)

I have finished the PCB layout and am in the process of getting the boards made. When they are tested out properly I will post the gerber files and the updated schematic. There are only minor changes that have been made to the schematic.
An object at rest, cannot be stopped!
