Resurrecting this ANCIENT thread, since I finally got a proper cabinet to install this nifty little amp head into! Since I am totally lacking in woodworking skills, the "nekkid" chassis had been...

The former, I'm sure! :dude:

Looks GREAT, Shiner!! :AOK:

Now....how will it sound?? :confused: ;)

Looks good, Shiner! :AOK: And VERY familiar!! ;)

When will the electrons flow??

I'm not sure it makes any difference. I kept the green on one side throughout, and the red on the other, including the power hookup end. But these are only the 6.3V filament heater wires, so I really...

Looks very good from here, Shiner. I'd need a higher resolution than that to see the individual solder point quality, but there aren't any ugly ones evident. NICE JOB!! :AOK: :bravo:

Lookin' aces so far there, Shiner! :AOK:

BTW, where'd you get the tubes and what kind?

Just a brief resurrection of this old thread just to underscore again what a cool little amp--and DIY project--the Firefly is....

I just finished a small modification to the amp, adding a rotary...

Certainly a familiar sight at my house, Shiner! :dude:

WHOA!! :eek: You really don't want to use that beast on the little Firefly PCB. W-a-a-a-y too much power. That's a soldering gun, not an iron. Get yourself a little Weller 25W job, or similar.
...

Yeah, buying individual parts "a la carte" is rather expensive, but a big part of a project like this is the enjoyment of building it and the satisfaction in having YOUR own amp, when it's done. Not...

Really haven't decided yet. Either plywood with a tolex/vinyal finish, or maybe just a nice wood enclosure, stained & urethaned. I'm really in no hurry, because (1) I'm enjoying playing the little...

I used a Hammond 1444-16 aluminum chassis that I ordered from Mouser.com. John Calhoun includes a template for this chassis (10"x6"x2") in his instructions.

Re: the holes, I handled eveything on...

Anybody interested in tackling this DIY amp project, refer to the resource links back in posts #1 and #10 in this thread. John Calhoun's PCB and detailed instructions (with full BOM/source/part #...

What did you say?? :confused: ;)

Two additional notes:


Though the Firefly is really about tube distortion, it's not purely a one-trick pony. Nobody's ever gonna confuse it with a Fender Twin, but if I put the 12AU7 tube back...

OK, here's a little sample of what the Firefly can do. I came across a posting at the AX84.com Firefly forum that said if you swap a 12AT7 for the 12AU7 power tube, it drops the max. power output but...

Got a schematic? I could use one of those! :D

As I understand these things, and amp will sound dark if the circuit is laid out such that a large portion of the high frequencies are lost/bled off to ground during the course of amplifying the...

Funny, that's how I feel about you when I hear your guitar playing! Thanks for your generous comments, Jimi. Really--the building is easier than the playing!

Well, after spending a bit more time with this little dynamo, I must admit I'm pretty impressed. It can generate an unbelievable amount of volume considering it's power rating (I suspect that 1.5W is...

WOO WOO WOO!!!! Finished the Firefly build and fired it up Saturday evening--worked the first time!! :dude: The chassis hasn't been painted yet, but it looks pretty cool just the same. Here are some...

I expect I'll use it extensively with both the 1x12 I assembled myself and the 2x12 Drive cab I bought during that insane Music123 close-out sale. A 4x12 would probably sound great, but it's getting...

Yeah, they're kinda quiet without power and output transformers wired in! ;)

BTW, some more excellent clips can be found at the following link. Scroll way down the page to the "Amps" section of...

Oh, sorry if I was misleading! No, the clip isn't me (I wish!!), it's a clip posted on the Firefly project page at AX84.com. Doesn't say who the player or the guitar is, though it certainly sounds...
