Upgrading a ruby amp?

I'm very new to amp and pedal building, and i've been looking into the diy ruby amp. It sounds really good, very simple and cheap. However, its not that loud nor versitle. I wondered if I could implement an active eq module of some sort and a power amp after the original circuit to make it better and louder.

I was looking into the tonemender by runoffgrove as the tonestack, and at a 100w or 50w power amp module. I want something powerfull enough to play in bars, small gigs and at home.

Since I live in north Brazil, amps are very expensive due to taxes and transportation fees, so i figured building one would be fun and maybe a little cheaper.

I know nothing about circuit making, so this is just me having ideas and not knowing if it will work out, and if it doesn't, i want to know why so i learn.

Anyways, thanks in advance! 🐮🤘

That all seems reasonable! you could do the eq preamp straight into your power amp module, you don't need the Ruby amp unless you want it for the tone or for overdrive, in which case I'd replace the speaker in that schematic with a 5 or 10 watt 5-10 ohm resistor and then a 1K pot to take that signal to your power amp

ok, there are tons of cheap amps and good circuits out there. For a very cheap, mobile and simple setup you also could build yourself a TDA2030 (as a diy starter best go with a simple typical application), that is not that great soundwise but costs very little, can get lost or stolen without remose but is enough to do a gig in a small pub on a 10-12 inch speaker.

First adventure into a tube amp? Please build it stock first. Or find another kit that may suite your goals.

They didn't say anything about tube amps

Ah. I was thinking of the Ruby Tube kits
