New guitar amp

[CiscoKid]

I have a thing for low-wattage guitar amplifiers. And the 1957 Fender 5F1 Champ is an iconic example. Many classic recordings were done using this circuit back in the day. The original 5F1 used an 8" speaker, but I upped that to a 12" Weber Red Dog rated at 15 watts and 4 ohms. I kept the circuit stock except for using a 5V4 rectifier tube instead of the 5Y3 the schematic calls for. The 5V4 has a slightly lower internal impedance making the amp slightly punchier with a stronger lower end.

Cabinet is maple with cherry inlaid dovetails. Oil finish.

That handle really doesn't look sturdy enough to carry the box once you fill the secret compartments with gold and silver bars.

I made an ozonator just like that, but without the dovetails.

No reverb tank?

What was the cost and where'd you source parts?

Kit from Weber was $600. Add another $40 to upgrade some tone caps to Sprague Orange Drops. Another $40 for the vintage 5V4 rectifier tube that came new in box, but I suspect is older than I am. Roughly $120 for the Red Dog speaker. I had the wood laying around. All in all, a fun little project.

Not the first amp I have built. Here's a 35 watt tube head with a V-front speaker cab I made out of black walnut. People always ask me why I built a V-front speaker cab and I tell them because nobody's done it since the late 40's and it was high time that somebody did. There's a pair of hemp cone 12" Tone Tubbies in that cabinet.

Those are fit for Glen Campbell.
