Tube Amp Archive

OK, thanks! I have a Hammond 290PAZ on the shelf... that should do for the PT right? I also have a Hammond 1620 OT... what do you think of that? 20W and 6k6 input impedance

on the far left of the boaed... is that 2.7k? thats the one I'm not sure of. and the grid resistors. thanks!

A guy gave me this circuit board. he thought it was a Trainwreck (its not), then thought maybe it was an AX84. the preamp looks similar but its got 2 power tubes (6BQ5/EL84). I got the board and a diagram of the lay out. the board is already built and looks pretty well done. I've checked the compone...

not sure where that would be.... this is a non-tube amp. quite an orphan is seems.

A friend has this Marlboro amp, I haven't seen it yet so not sure of the exact model but I think it a GBO 520B, 3 inputs... Guitar/Bass/Organ, about 30-40 watts, one 15" speaker. Pretty sure its all solid state. he's had it a while & likes it but it is now starting to fade out after it heats up (20 ...

forgot to mention Sams don't have anything

I got one. complete & working. I've been looking for a schematic but dayum.... this is the most orphan POS ever. even the antique radio forums come up blank. what I know: 50's PA system with weirdo fairly high voltage output tranny. probably pretty "lo-fi" . I did a search here and found one thread ...

a couple years ago I started to build a TW clone and bought a Pacific PAC 415. but, I lost, or didn't have specs on it. I looked around and didn't really find anything. anybody got info?

I've been looking but I can't find any vendor that sells the Pacific 14415...

ish...

a good amp can make a crappy guitar sound at least OK. a crappy amp will make even a great guitar sound bad. this I know to be true

any forward motion on this project? looks interesting

I'm pretty interested in building that '97 Skyliner amp referenced in post #1. is there a picture somewhere of the main board? I've spent a lot of hours looking but can't find that one... I would love to see the layout.

hmmmm.... not on my computer. they go to "downloads" as "file.php" and nothing I have will open them, even the "Express sch" schematic program. Windows 10

I can't open the downloads in the 2nd post on this thread.... would love to check them out.

nice lookin' rig. and how about that Speaker Wearhouse speaker..... I got one in a project & wowzer, pretty sweet
