Crowncorder CTR5300
« on: December 25, 2021, 04:25:56 pm »
I got this as an add to sweeten a really nice deal on another device!

I got this idea when checking it out, would be possible to convert it into a mini guitar amp with a leslie device using the motor,  If so how ?

no
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

I think there is use for the components at least, if they are working!
The transistors are 2SB75 (x6) similar to NKT275, some pedals use it. Like the EHX Germanium OD.
