Could this work for a 4 tube PP output running at 50w?
« on: August 10, 2012, 08:48:30 pm »
I've read on this forum about a few amps that are SE with two power tubes running at 12w, and also a marshall with four tubes in PP running 50w. This has been very interesting to me as i am getting ready to build a 50w jcm800 type amp and would like to try for a PP w/ 4 tubes at 50w. I doodled a schematic and was looking for some input on the design. I looked at the clavioline schematic on this forum and tried to adapt it to a PP setup. I copied the values from the clav onto this design so cap and resistor values are probably wrong in it.

You must remove the cap/resistor pairs that are between the OT and tube plates.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!
