It does sound quite muddy. Is it the amp or the recording?

Seems to have great dynamic & distortion response though.

@cableaddict it's got a tiny output transformer, and is using a tube generally used for preamps as the power tube, so I'd guess that that's why it sounds muddy.

Very cool! I built one too, and I can't decide if I want to mount it in a homemade combo enclosure, or if I want to get a piece of walnut (like for a trophy or plaque) to mount it on for display.. Hmm.

IIRC, the first (both triodes in cascode I think) it's a booster you can switch on or off, the second has the two main triodes of the pre and the third works as a power tube

[kuzyaka88]

Is this push-pull amp?

I see 3 dual triodes. The first one is a preamp tube, the second one is a phase inverter, and the third one is a power amp. Like in Russian Yerasov Gavrosh 8. Am I right?

I tried to run a GAS 89dB/1W on a T-amp during a festival this summer and though the 55h car battery lasted a full week I could not really compete with the crowd when it got really wild. How would 1 watt be able to supply any volume? I noticed also that the bass suffered and the lower freq were cut when it got too loud.

These aren't meant for serious gigging, can't push enough air, this is an apartment type amp, or for close-miking in studio.

@kerranz

It's perfect for gigging. You just use a mic, then the stage volume is under control & everyone can here each other. My guitarists uses a 2-watt amp, and it's almost too loud.

[kerranz]

@cableaddict As I said it's fine if you're going to mic it, but of course that adds a generation in the sound, adding mic capabilities (or weaknesses), cables and board and whatever's in between. Can't always trust the house PA or wiring.

[Renegadrian]

Good project!!! I think I'll build one sooner or later...

[lookagain77]

approximately how much did it cost you to build this amp? with hardware, chassis and all (tubes excluded)?

[bastardmakervdh]

clean up the tone a little bit or use a better mic for recording but I can tell that the warm tube sound is there...nice job! nice lead channel, but the powerchords sound too sloppy. you need a better edge to it IMO. maybe its just the recording though.

[gitarnik666]

great tone, but can You get some nice clean sound out of it?

[jeremyhogan]

@plexisound google "firefly amp" and the plans and parts list are the first hit.
