Title: Crate V100H Switch Mode Power Supply schematic
Post by: LHPcope on October 17, 2013, 09:25:57 am

Hey all,

Does anyone have a schematic of the SM power supply for a Crate V100H?  This is a tube amp with a solid state switch mode power supply.  I have one on the bench which came in with two of the EL34s bad and looks like they took the power supply out as well (At least all three mosfet choppers are dead.) 

Loud Technologies that purchased Crate no longer supports this thing in any way I'm being told by the local Crate dealer; so no schematic from them nor are they selling replacement SM modules.

Thanks,

Dave C.
