Matamp GT120 clone build
« on: January 02, 2024, 04:30:42 pm »
Hi all, just getting around to documenting my latest build, a clone of a GT120 with the PCB and chassis from Hillbish Design and thought I'd share here in case anyone is interested. Here's a page with the initial details - I'll update it as I finish it up. https://hiegdk.com/GT120/

Edit: Adding a couple photos

That looks like a very nice project. Looks very nice and clean.

Those beasts are loud as hell.
Tried one once, when visiting the Matamp factory. It is a great amp, certainly for stoner-stuff, but way too loud for my purposes.

What inductor, if any, did you use in the presence (resonance?) circuit?

I used this - not sure if it's appropriate, but it seemed about right: https://www.mouser.ca/ProductDetail/Bourns/8250-104K-RC?qs=SE07hN747nEftvNJ7TFnKQ%3D%3D

That's some really nice looking work!

I purchased the Hilbish board & chassis back in December and came across your post while sourcing parts.  This is going to be my first build that's not a full kit and I'm just starting to get all the components together.  I had to say thanks for posting all the build pics and BoM links.  They're going to really help me out as I work on this project.
