Hey guys, here's an update on my progress: I work at a non profit research institute (don't worry, I'm not a scientist, I do the shipping & receiving) and I found out that we have a guy here that is a wiz electrical engineer. We hooked the PT up to his super nice MM in his workshop and he says that ...

You guys must be rolling your eyes so bad right now, haha. Thanks for sticking with this. My buddy told me that same thing about a MM not being able to read clearly through components. Those Fluke MMs have a range setting on them, though, which allowed to get a clear continuity reading for every sin...

I was using one of those nice Fluke MMs too (I borrowed it from an electrician buddy at work) so I doubt that the MM was giving me...

Well, guys, I think I got to the bottom of it. It was pretty simple afterall. It turns out, apparently because I'm new at this, that I burned out most of the components getting them all soldered up. ...Oops. So, for my next time through I plan to do some things a little differently. My first run thr...

Okay, so I need to be looking for a bum ground then? That helps narrow it down, thanks! No kidding about this being addictive. This basically turned into my second job. :roll: I'm not an expert in electronics in any sense, I'm a musician that wants to be able to build my own tone out of what I have ...

Hi guys. I recently finished a complete gut and rebuild of my version 3 valve jr using the Watts Tube Audio Voxy kit and a Watts Heyboer OT upgrade. Well, I fired her up and things didn't go like I hoped. I'm hearing a louder-than-normal buzzing sound coming from what I think is the PT and I'm smell...
