Jupiter Vintage Tone Guitar Amplifier Coupling Capacitors - Replacement for Astron/Sprague
Handmade in USA with USA materials by Jupiter Condenser
Designed as replacements for the Astrons used in vintage tweed
Fenders and Gibsons, and the blue molded caps used in brown and blackface Fenders, and other vintage guitar amplifiers.
These film and foil capacitors are the top choice for vintage tone in the repair of 50s and 60s
amplifiers and in new builds of vintage-style amplifiers. Extra long leads for restoration of actual point-to-point wired
vintage amplifiers.
Also an excellent choice for Gibson and Fender guitar tone circuits.
The line marks the outer foil lead.

Testimonials for Jupiter Vintage Tone Caps
"These are the finest coupling caps I have ever used in my amps. These are the ONLY coupling caps I will use in my amps! They produce great overtones, warmth and all of the juicy harmonics you'd expect from your amp. Your amp actually breathes with these caps."

Rob Chwaliszewski, Buffalo Amplifiers"I replaced all the caps in the 3 values currently offered in my Blackface Super Reverb build. The tonal improvement was immediately noticeable and amazing, brilliant clarity, perfectly clean. Smooth grind with amp above 7. This is a stock build, no hotswitches, no Master Volume."

Dave P."I've read a bunch of discussions on the 'net about coupling caps in tube amps, and it seems the only common thread was a lack of consensus. I guess I can understand that now, because even though the tone with the Orange Drops was more objectionable to me, you could still lump them in with the rest and say there really wasn't a huge difference from one type to another. I couldn't say that about the Jupiters, though. You could definitely hear the improvement in tone."

Greg K."I'm having a little trouble imagining this amp sounding any better than it does now. I swapped out the 4 caps yesterday. That's C2, and C1, C8 and C9 in the fixed "tone stack." What I ended up with surprised the hell out of me; I just didn't expect there to be such a striking difference in the timbre of the amp.
The low end is tighter and less mushy, and the high end is smoother and no longer screechy and clanky. (It sounds like I'm describing some of the 7 dwarves here.) It's just warm and full, and it's lost that small-amp harshness.
I'm sorry I was so skeptical about these caps. I couldn't conceive how changing a few inexpensive components can have such a profound impact on the sound (and feel) of an amp. But there it is; my Champion 600 acts like a completely different amp. One that's bigger, more expensive, and more refined through the stock speaker, and through my V30 it sounds like a Deluxe or a Princeton, maybe even a Pro.
Thanks again, man, this thing rocks!"
Tim H."For vintage tube guitar amps circuits, I don't think you'll find a better new production cap available. These caps nail the vintage sound and response of the old Astrons and Sprague. The closest thing I can compare them to is the blue molded Sprague caps I've taken out of a 1966 Blackface Super Reverb (yes, I put them back). I've used the Jupiter caps in 3 amps that I have built, a 5E5A Pro circuit, A 5C3 Deluxe circuit, and a 5C1 Champ circuit. In the 5E5A Pro I originally used Orange Drop caps. I played hundreds of gigs on this amp over a two year period. It always sounded great, and I always received compliments on the tone, but to me there was always a bit of graininess in the sound. After installing the Jupiter caps, the difference was dramatic, not only did the Pro sound warmer, and sweeter (think more harmonics), it actually had a bit more gain to it. The Jupiter caps really made an amp that was great sounding to begin with sound "even better".
The upgrade to the Jupiter caps in my other two amps yielded similar results. I was pleasantly surprised to find that my tweed Champ and Deluxe circuits sounded and responded more like "Old Fenders" A lot of people swear by the $10 - $20 foil in oil caps. I've always thought that these sounded "to clean" for guitar amps. Certainly they sound great in a tube stereo amp, but I've found that they are very sterile sounding in guitar amps. Don't fall for the hype on oil caps, you won't find them in any old vintage guitar amps. What you will find are caps that the Jupiter caps were designed around. Check them out, you won't be sorry!
