The Amp Garage

+1 for Steve and Apex Jr. I guess I got lucky. I use his solid core teflon coated wire all the time and the cheap-ass pair of wire strippers I bought (in conjunction with a whole bunch of other cheap-ass tools), strips teflon like butter. Everything from 18 - 22 guage. Never had the slightest proble...

Wired up my first FET circuit!!!! All I had was a MPF102, so have used that to test it until my NTE452's arrive. I think I'll change the capacitors throughout as well. In my Pentode build I used yellow tubulars and the amp sounded a bit dark, so for this amp I used 715/6 orange drops and this amp i...

Pretty cool one from my old neighborhood..... http://www.youtube.com/watch?v=SCctP9kStKg Love that. Thanks for sharing. Glad you liked it Lefty! The lead guitarist was a guy named Seab Meador. He was kind of a legend in the Dallas, Ft Worth area in the 60's and 70's. In the 70's he had a great band...

Part of the Ampeg mojo is that it has to weigh over 75lbs. It's all about the "girth".

Thanks guys, the finger is inching farther and farther away from the "Place Bid" button.

Just to follow up for those interested. Looks like the JFET was a 300 volt 2N6449. Looks like these are in fact pretty difficult to source. Apparently, Jim Evans originally designed this as a tube amp and he wound up wiring the JFETs right to the unused tube sockets on the earliest models. Amp also ...

Thanks Rooster. That's kinda the impression I've got as well. I was hoping I could find a part number for those high-voltage FETs, but haven't been able to find even a schematic. I'm still curious, but it's starting to look a no-go.

Anyone here know anything about the old Evans amps? I am aware of the general history of the Evans amp company going back to their starting days in Texarkana, but I don't seem to be able to find any schematics, or any kind of circuit documentation online. I'm curious because there is one for sale on...

I have a Weber AC30TB chassis that I put a Rocket(TB) channel, a Normal channel and an EF86 channel in. (The EF86 channel and the Normal channel are connected to the same side of the PI as the TB channel with a center position on the toggle to disconnect both channels entirely, BTW, to make it iden...

V2's are hard to come. VT40's are much more common. Fliptops sells the transformers - and lots of other parts for Ampegs. It's gonna be a lot cheaper to buy a used one than build one. Great amps. Been gigging with a VT40 for the last 5 years or so. The master volume is a huge help on these guys and...

I always thought the gateway to great tone was in your fingers.
Boy have I been doing wrong!!

I had an old VT-40 in the 70's. Great sounding amp. Ampeg mounted their preamp tube sockets on the PC board (obvious). I hate that design. With the tubes-down design everything on that board is subjected to way too much heat, and the heat up-cool down cycle plays havoc with everything. Too bad, caus...
