Firefly 1.5W Tube Amp Build

[luvmyshiner]

Aren't you just the cutest little amp? Yes, you are! Yes, you are!

Snicker.

DVM, I just ordered the JJ Electronics tubes from tubesandmore.com. But I did pick up both the 12AT7 and the 12AU7 to swap out like you suggested.

OK, here's a picture of the bottom. Let me know if y'all see anything that looks like a problem.

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!! :

[luvmyshiner]

Thanks DVM. I had to take it outside to get enough light, and its getting dark now. But tomorrow I'll jack up the resolution on the camera and try to get another shot.

I'd especially appreciate it if you took a look at the wires. It appeared to me that the red wire stayed in the bottom holes until they got to the power at the far left, then red went top (yup, that's technical talk y'all). That's the way I wired it, but I'd feel more comfortable if you confirmed that.

If I did that you would say nice job, but it would be because you would think I made a silver platter - no green to be seen

Nice job Shiner.

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 don't think current direction matters, or the instructions would make a point of that. When you power up the first time (main power switch on, but the standby switch still off), the filament heaters should energize and glow orange in all 3 tubes. If they don't, no harm done--you'd just have to rewire it.

Well it's been awhile since I posted my progress, but I didn't want y'all to think I had forgotten this little project. I ran into some problems drilling out the box, but my son brought his Dremel down this weekend and I was able to finish the box. I haven't finished the final wiring yet because I'd like to paint the box, but I put everything together just to make sure it all fit ok. I have to say this thing is a lot heavier then I thought it would be.

Looks good, Shiner! : And VERY familiar!!

When will the electrons flow??

[Katastrophe]

Very cool, Shiner! Are you going to build a wooden surround for the head to match the speaker cabinet? If so, you'd only have to paint the front of the head.

Great Point Kat.......Shine would only need to paint the control panel side and I think a head cabinet that matches his speaker cab would look sharp.

[tot_Ou_tard]

Screw the paint . Wire it up Shiner; we want clips!

[luvmyshiner]

Hey Kat, I was planning on building a matching cabinet for it, and your suggestion sounds great!:

DVM, CB's Grandmother is coming in for a visit this week, and my daughter is coming in for a visit next week, so that may slow me down on a few projects. But be patient with me, I'll finish it up eventually

[luvmyshiner]

Even with the kids in town, I managed to paint the amph. Kat, I was going to just paint the front, but I've never been happy with the lines I get from tape. So I figured what the hell, and went ahead and painted the whole thing.

DVM, with the long weekend coming up, I'm hoping we'll have electrons flowing (or exploding stuff), before next Monday. Keep your fingers crossed.

I really wanted to paint it black, but I want to label the controls, and I remembered what DVM said about keeping the color light enough to see the letters. So I compromised. The red is still pretty dark, but it's better than black.

Well, it's either going to sound really great, or it's going to sound like . . . psssszzt . . . BANG . . . . (smoke).
