I have 3 types of capacitors I want to replace in my amp, and I just want to make sure I'm on the correct track to do this.

The 3 are rated:

Inter-stage / Coupling caps:
#1: 0.47uf @ 630v
#2: 100uf @ 100v

DC power cap:
#3: 10uf @ 500v

Here are pictures of them:

There are the caps I picked out to replace them all, just want to make sure I'm picking ones that will work:

#1: https://www.parts-express.com/jantzen-audio-047uf-800v-z-superior-capacitor--027-468
#2: https://www.parts-express.com/jantzen-audio-100uf-400v-crosscap-capacitor--027-956
#3: https://www.parts-express.com/jantzen-audio-10uf-800v-z-superior-capacitor--027-497

Thoughts?

Yes, those are fine (as long as they fit). You can always go up in voltage, but never down.

Also, you can probably get away with a cheaper filter cap for the DC... they don't make as much of a sonic difference as the coupling caps. A $5 Solen would work perfectly well and allow you to put the money elsewhere (such as getting nicer 0.47uf caps).

Looking at the pictures, I assume this is a tube amp? You might want to look at Jupiters for the bypass coupling caps, they sound great.

Thanks for the advice.
The filter cap is an F&T, same brand as the bypass caps. But the Jantzen filter cap is only $45, worth a try I guess.
As for the other two caps, the .47uf/630v are the inter-stage / coupling caps, and I guess the 100uf/100v are the "bypass" caps.

I like Jantzen, and I think they would be a real improvement over the Solen coupling caps, the pair would only be $30
The bypass caps a bit pricier (because of 100uf rating) so the Jantzens I picked out are $70 a pair

I have read good things about the Jupiter caps, and out of all three of these capacitors, replacing the coupling caps are the most important and will change the sound the most.
So maybe it would be a good idea to invest the most in that specific pair of caps. The Jupiter .47uf 600V are $200 for a pair, versus the $30 Jantzen pair, but it may be worth it? hmmmm

Right, F&T is from Germany IIRC, they're one of the very small handful of suppliers offering axial electrolytics above 450v (Sprague and Illinois Capacitor are the other two). They're good caps but film will sound much better. Yes you're correct, coupling and output caps are a good place to put your money for upgrades.

Jupiter makes an aluminum foil line for half the price of the copper, and they sound great too. I mostly use the aluminum foil line but I have used the copper foil in my DAC (same 0.47uf size). Once they burned in they sounded notably better than the Audio Note aluminum foil in oil caps that were in there before. The Red Astron and Yellow vintage tone are more for guitar amps and vintage rebuilds.

Ok I think I got my choices clearer now.

The Jantzen bypass caps measurements were too big for my case after I measured, so I'm going to go with these for the bypass caps: http://www.partsconnexion.com/product31089.html
For the coupling caps I'll take your suggestion and go with JUPITER-78885 found here http://www.partsconnexion.com/capacitor_film_jupiter_copper600.html
I'll stick with my Jantzen for the PSU filter cap: https://www.parts-express.com/jantzen-audio-10uf-800v-z-superior-capacitor--027-497

Thanks!

Edit: Just ordered all these linked, hope it works out

Let me know how you like the AN electrolytics. PCX just started carrying end of last year IIRC. Given they are AN one would assume they'd be top-notch, but I haven't used in any of my projects yet.

Ya I'll let you know for sure, but idk how I'll really be able to tell because I'll be putting in the Jupiters at the same time.

And for anybody curious which amp I'm doing this on, it's the iha1 https://www.moon-audio.com/dragon-inspire-iha-1-tube-headphone-amp.html

Ah the Dennis Had 6SN7 unit. Very cool. If you have a chance could you take a photo of the entire inside layout. There don't seem to be any floating around on the web. Hope the mods go well!

I already had an album created for that https://imgur.com/a/pjkbG
