Title: Crowncorder CTR5300
Post by: uki 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 ?

I think there is use for the components at least, if they are working!
The transistors are 2SB75 (https://www.radiomuseum.org/tubes/tube_2sb75.html) (x6) similar to NKT275, some pedals use it. Like the EHX Germanium OD.
