Coloursound Power Boost Build

For those of you who like looking at stuff....

I based it on the 1969 version - BC109 transistors, Vintage caps etc and tried to preserve the original pcb layout, Runs on 9v or 18v for extra volume/headroom.

It's a bit scrappy, next one will be more refined hopefully.

Never knew these Power Boost's sounded so good at full drive. Very unique wet, spitty, focused distortion..

Looks great, I really like your knob and switch layout. I love Power Boosts.

Cheers, I inverted the drive pot from the original layout and added a volume pot on the board; tight squeeze in a 1590BB2 enclosure, Now I've made one, I love them too.

Did you design and etch the board yourself?

Hey, Yes, I started with the original 1969 layout and moved it around slightly using DIYLC program. Toner transfer onto single sided Fibreglass board and etch. I hate modern pcb's, I prefer the single sided vintage look using full size vintage parts.

Howdy, Stranger!
