Vox AC100/2 build video series
« on: January 12, 2016, 09:38:55 pm »
I've got the first video done, its here:

https://www.youtube.com/watch?v=EgbUJUm1rSU

It just talks a bit about the schematic etc, its 10 mins, I'm going to keep releasing more videos on the process etc, I'm hoping to have it help others learn as I do (from my mistakes :)  I'd love to refer to some people involved, if you've posted on the other threads and want a thank you on subsequent videos, please do give me your okay, I don't like involving people without their okay :)  (Even though you're somewhat hidden behind the forum alias).

Let me know what you think of the first video.  It may take some time for it to get the full 1080p verison available, but for now the first one is a bit lower def.  If you want to wait until the full version is there go for it.   Also please correct me in the comments here or on the youtube channel, I'd love to help make sure I'm not misleading anyone!

Thanks again to all that helped!

If anyone is following along, here's video 6, power on, and some oscilloscope testing.

What's the status of this amp? Last I heard most all the tubes were dead.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Yeah I'm waiting on new tubes now, all of them... It was nice to spend another hundred dollars on it ... :(

Last status, though, before I put that tube in that was shorted between pins 2 and 3 was that it was working but the overdrive and break up was happening too fast (I had all 12AX7's in it, now I'll put back in the schematic spec 12AU7's).

I'll post back after I get it back up again.

Video 7, progress is coming if you go back to the main thread, I've fixed the power stage issues, now I have to clean up the preamp section :(

Video 8 is up with some audio.   Still trying to sort out what's wrong, but boy does it sound cool at two tubes/50 watts mode.

Latest video is up, Check it out, I have audio of the guitar playing (Sadly we found out later that we were clipping a bit on the clean pre-reverb part, and it was a bit soft in the reverb)  Recording in the garage ain't easy lol

The last video showing the final cabinet and letting y'all listen to it.  The reverb's mighty light, sadly, but otherwise its working like a charm:
