AX84 amp designs... anyone used them?

[MikeS]

I’m thinking about starting off simply with the AX84 P-1 design… just to get my feet wet. I’ve really been wanting to dive into the world of amplifiers, and since I’m a “hands-on” learner this type of beginner type build might be perfect.

Anyone built using AX84’s designs? How did it turn out?

Once or twice. Made the mistake of starting with the HO and doing my own layout in a less-than-ideal combo chassis. It had some layout/ lead dress/ oscillation issues. But later builds of the same circuit showed me that layout/ lead dress really do affect tone even when all the parts are the same.

Start with the P1 or octal P1. Leave room for a second preamp tube so you can convert to an HO later if you want to.
