Alamo Paragon

[gui_tarzan]

I've looked high and low and even contacted one of the guys that used to own the company and still can't find a schematic for this amp. I need to rebuild it from scratch, the guts are missing. It was my first amp, otherwise I'd just make a Bassman out of it.

lots of different flavors of Paragon amps apparently, most basically Fender clones but later adding SS bits. And no one seems to have schematics, kind of funny since you're not supposed to forget the Alamo...

I'd figure out the transformers, the OT being the most mysterious, RG has a great page on testing them here
Output Transformers
then build a real Fender if you can find the tubes!

I was hoping to find one though and return it to the stock circuit, there seems to be a cult following among the blues players in our area for Alamo amps. They have a distinctive sound.

[tedmich]

more of a cult following for Fenders I'd wager, and no shortage of schematics. You could borrow an old blueser's unit and copy it; they are probably not that complex..., good luck!

Agree, borrow or even rent some guy's amp, and draw up a schematic from it. Basic enough amp, should be simple.

If you have to offer to do maintenance to it while in there.

[gui_tarzan]

I will do that if I can find one! The ones I've seen around here are either the Capri or one other one there's already a schematic for. This one has four TIS-58 transistors in the pre-amp, a 12AX7 and a pair of 6L6s on the tube chart.

The book "Remember The Alamo" is on Google. I can see part of the Alamo section but not all of it, I might have to pick that up. Here's what my amp looked like originally:



All I have now is the head, the cabinet perished after a few moves years ago.

I guess unless I find one intact I'm going to use the chassis with a Bassman circuit. One of these days.

Yikes!

borrow for 6 months?? ;P Maybe there is a reason there are no schematics out there, rats nests were their own "copy protection" mechanisms...


think a 6U8A can sub for the 7199

[Justin Thomas]

I believe there's a very minor circuit mod that has to go with that 6u8/7199... yup, got it from tubedepot.com

If the amp is wired for 7199:

Remove wire from pin 2 and relocate to pin 6.
Remove wire from pin 6 and relocate to pin 7.
Remove wire from pin 7 and relocate to pin 2.
Label tube socket that it's ben wired for 6U8.

I've got a couple of 6U8s, I think they're NOS RCA from the late 50s-early 60s.

Yes there are. Mine says 7+75 on the tube chart. According to the books that have been referenced, my model was a "piggy-back" head on a 2x15" cab which is what it had when I got it.
