Vox AC100/2 build

Greg,

Absolutely, I learned a lot from the project, and am excited for the next! :) 

As for the distortion at max volume, I had the microphone set too hot, I was trying to get it good enough for the lower volume stuff, and then when I played it at max volume it kept clipping, the noise is from the mic/recording.  The tone has only a nice overdrive sort of crunch to it, no distortion that I can speak of.  My wife was there helping me film and she also agreed it was nice and overdriven, but not distorted like in the video.  Also the reverb sounds obvious but soft, but in the video/recording, I think the levels were too low, so it ended up a bit hard to hear.

Hi Phil,


That makes sense and is what I thought might be happening. So now that you have it working correctly are you going to stick with the original 12AU7 input stage and phase inverter or will you use a 12AX7 or something else for more gain?


I like the sound of the original circuit myself, and just added a second higher gain channel in my amp and that approach works well. I don't have reverb added to mine....I think it sounds fine without, and I have a Fender reverb amp to use if I want reverb anyway. My project is sidelined for awhile still though but I hope to get back to it and finish it sooner rather than later.


Cheers!

I actually didn't try going back to the 12AX7 for any of hte PI or first tube, but I don't necessarily need the OD, I am likely to sell this amp as I don't have need for a 100 watter.  (I was trying to repair and re-sell the original AC100CPH but it was so badly damaged, I gave up :D)

I don't have space to start collecting all the amps I want to build :)  Since I'm about to start another build I'm going to have to make space for it.

Yeah 100 watts is a bit much for guitar unless you add power scaling, and with the AC100 being so clean there wouldn't be much point in adding power scaling to it, so it ends up being just a very loud, harmonically rich amp. Hopefully someone buys it when you go to sell it.
