The Amp Garage

I installed a switch so that I can go back and forth. To me it sounds best on 5200 with that aggressive edge.

Swap the tubes around and see if the glowing plate goes with the tube or stays with the socket.

Looks like it came together really well. I can't wait to hear it.

I bought one of these a few years ago, and it has worked great.

I have tried both EL34's and 6V6's. I like the EL34's the best. I have a 4x12 loaded with Greenbacks and a 2x12 loaded with Hellatone 30's (G12H30's). I like the EL34's and 4x12 Greenbacks combo the best.

Man that is a nice looking build. How does it sound? Now we have 2 of the same amps (Express and Fender SR). I just finished up my Express Clone about 2 weeks ago. Man they are beast. Have you tried 6V6's yet?

Yeah I re-routed some wires before, but now if I set the amp on top of the cabinet I get the whistle. I can pick the amp up about an inch and it goes away. Set the amp back down and the whistle comes back. It is definitely cabinet interference, because if I set it on top of my 2x12 cabinet it works ...

What did you use for your shielding plate, and how big did you make it?

Before using shielded cable try shielding the chassis (bottom plate) cured my problem! OK I tried putting a sheet of Aluminum Rolled Flashing from the local hardware store. I cut it to the size of the opening of the chassis bottom. I set the amp back on top of the cabinet and it still whistles abou...

I am in the process of trying that now. I just happened to pick the amp up to set my Furman in under it, and walah the whistle went away. So I have got some flashing and I am going to give that a try. Thanks.

You guessed it. It sounds great. The only issue is that I need to put some shielded cable on the Presence control to get ride of a whistle when the Presence control is cranked.

Well it was a long trip, but I finally got the Express completed. I would like to thank all of you guys on this forum that was a great help in getting this completed. Everyone helped, but I wouldn't have been able to complete this without the help of Nic over at CeriaTone, Dana, and Moose.

Were is the best source for the PEC potentiometers in the US?

The Ceriatone and other Express amps don't have a linear volume pot. They have an audio pot. The Middle and Presence controls are the only linear pots in the Express.

What do I need to do if my bias pot will not allow me to get the 6v6's in range? I have the EL34's running at 43.9 ma @ -30 volts, so that is way to hot for 6v6's right?
