The Amp Garage

That got me in range. Hopefully my tubes will be in next week and I can finish firing this thing up.

Thanks guys! I hoped some fresh eyes would do it. I'll try to get those fixed and check it again. I can't believe I messed those up. You think you're being careful as you go through the build but it's easy to make a mistake.

I just found that the DV voltage of the center pin of the trim pot varies as you adjust the POT from 0V to -12.3V but pin 3 is 0V. Pin 1 is always -12.3V. Pin 2 and three are both connected to ground so shouldn't they both be 0V and pin 1 should vary when you adjust the POT?

Finally pulled the amp back out to try to get it going. Went through the first steps again and ran into the same issue after going through the power supply section and re-flowing some of the solder. The max negative voltage on pin 5 of the power tubes is about -12.7V. The other voltages look pretty ...

Thanks. I'll try to get some pics uploaded this weekend. That's the layout I've been following to check my wiring. I did find two bad solder joints and fixed those tonight. I think that someone doesn't want me to finish this amp. I broke one of the power tubes removing it earlier today when I was st...

I did end up getting a different switch and that worked out better, but I ran into some issues with the turn up and kind of just set this aside for over a year. I decided to get back to it and started the turn up procedure. And it failed the first step! Going by the document, it says to find the max...

I wish I had seen this before I went shopping yesterday. I used to get them at RadioShack but that's no good anymore. I needed some things from Valvestorm anyway so I ordered some. If I get back to town before they come in, I'll pick some up.

Thanks!

I build amps, guitars and pedals and don't have a lot of time or money to dedicate to any one hobby. This means that my builds are really slow. The Express build has been no different. I finished it tonight and started the power up with a bulb limiter using the instructions in the build document and...

Anyone heard anything on the new Vertex T Drive coming out soon based on the most Express-ive amp of all time? Should be interesting.

A lot of people reference Novella:

And of course pretty much all of the dirty guitar parts on Brad Paisley's Play album were recorded on a Trainwreck.

Glad to see you posting agian. I hope all is well and things are getting better for you.

We all wish you a speedy and complete recovery.

Awesome! Thanks again.

Thanks Mark. I built the cabinet and covered it. You can see on the back side that the corners are a little sloppy. I had planned on using corners on the back but I haven't found any to fit the 90 degree edges. It looks pretty good if you don't look too close! I also made the head cab for my 100W Pl...

Before I take this apart to start working on the reverb, I thought I'd take a couple of shots and show what the finished project looks like. I ended up ordering the faceplate before I came up with a logo so there is a nice open space waiting for it. I guess I'll either have to make a sticker or scre...

I did finally figure out what was causing the issue. The cap stack was taller than the chassis but I couldn't find anything else that was touchig between the amp and cabinet. I routed out a small pocket in the cabinet where the caps would have made contact and that seems to have fixed the issue. We ...
