The Amp Garage

Four output tubes, looks like a terminal strip with some silicon diodes.

Three Altecs, my aching back!

Do we have to beg? Okay - pleeeeeeeeease?

Could the ticking be an audio-frequency artifact or alias of some ultrasonic oscillation?

Isn't this the same #14x amp that's been for sale for ages?

Novice newbie here....please go easy on me. Built a TweedleDee Deluxe with the great information available here. I don’t understand schematics and used the layout that’s here. She’s running. Voltages are very close to what was posted on CW’s documentation. Except for one. At the intersection of the...

The photos are the "Hoyt Axton" amp, right?

Even though both circuits are different, I prefer the Odyssey/Winterland style PI/Driver. Or to put it another way, out of my five builds those are the two that I play most. Aaron Thanks, Aaron! The Odyssey/Winterland style PI/Driver is what I'm leaning towards, actually. Any chance you don't mind ...

Before you buy a transformer, check the power switch. Those Carling switches can fail and short a pole of the switch to the threads - connecting your AC to the chassis.

I'm not saying that's what's happened here, but it is a possible failure mode I've seen.

Someone's got an online Duncan Tone Stack Calculator that includes Dumble Rock and Jazz tabs, so you can sweep through the controls yourself. https://www.guitarscience.net/tsc/dumble_rock2.htm https://www.guitarscience.net/tsc/dumble_jazz2.htm Dunno why the downloadable version of the TSC does not i...

is there any advantage using these tubes Tony over the regular Ax7 other than if you have a box full of them? :) M Yeah! It's quiet less noise like Mr dB mentions the lower output impedance affects frequency response = more treble= a clear top end without having to use the bright caps=less harshnes...

And now for some Sunday afternoon guitar torture, a new vid. Not miked up properly, but cam was not clipping or compressing either. Still I think the mids aren't fat enough on the neck. Doesn't really sing when low gain, but might need a lot more volume to achieve that. DmRt56MKqZY Both videos soun...

6DJ8/ECC88 has a lower output impedance and more current drive ability than a 12AX7.

With 6L6's you have four tubes dissipating say 18W from the plates, and another 5.7W from the filaments, so nearly 100W, heating the power end of the chassis from below. No doubt the heat will age some components more quickly. If you are going to have it running for many hours at a stretch, maybe c...

Very tidy!
