opinions on sprague 715p and mallory 150 caps

[JD0x0]

Heres the deal im looking to purchase a kit called "Halle" as far as i can tell its a rough copy of a 90's HRM with the controls on the front of the amp. Im not looking for a "perfect" dumble, this is going to be MY amp on this platform, with my custom tonestack and switching.

Anyway for $15 more i have the choice between the 715p "orange drops" and the mallory 150 caps. I know that no cap sounds "better" just different thats why i'm looking for your opinions on the different sound and characteristics of them.

Thanks everyone,

Mallory 150's

Mallory 150's

Great that you like them! what in particular makes you like them more than the Spragues, apart from the mallorys being used in old Marshalls

Most peoples' choice seems to be 6PS polyester in an orange drop, not 715/716 polypropylene, for Dumble type circuits. Some caps DO sound better in the right circuit. Some people like SOZO caps which are modern Marshall mustard caps, these are a bit different again.

I like the Mallory 150s in old Fender circuits, but they are a bit too smooth for Dumble type circuits, most experienced people say. SOZOs are great in Marshall circuits, not quite so smooth IMHO as 150s.

Your choice is the Mallory 150s should sound smoother than the 715 orange drops, but less emotional, perhaps less involving. Personally I would go with the flow, get the basic 715 option and replace them with 6PS caps if you don't like the tone. 6PS claim to fame is big open (mid) range with an attitude.

Double post.

k...what I originally wrote and deleted was...'better un-stuffed.' Use Xicon MPPs or 6PS caps. I thought it was between the two choices and I've found 715s to be wrong (too hi-fi) pretty much everywhere. Mallory 150s are decent caps.

Before you purchase the Halle, look into the Brownote kits. Moss and Norm have doe more research on Dumbles than Weber and selects components based on what sounds best in these amps, as opposed to what's in stock.

The Halle is a poor excuse for a Dumble. The circuit is incorrect and the layout is also not correct. I have no doubts that the Halle will make a decent amp, it just won't be a Dunble like amp.

Ditto that

Take a look at the schemo: https://taweber.powweb.com/store/halle_schem.jpg , there's a lot of differences like cathode values on V1a and V3b etc..
Go for a Brown note kit or Ceriatone.
The Weber is a different animal all together.

Just the other day I replaced a 715P cap with a 6PS of the same value, so here are my impressions: The 6 PS is more midrangey overall, less highs and lows, but most important it has less pick attack, very much to my liking.To me it sounds like the difference between Alnico and ceramic magnet speakers.I would definitely go for the 6PS in a Dumble-style amp,
although I know HAD used other types as well.Just makes things easier.
I wasn´t as happy with the Xicons, though.Good caps, but I like the PS much better in these circuits.
Have fun Marcos

I am in no way one of the technical savants that comprise a lot of the membership of this forum, but I will say that I actually preferred the sound of Xicons in the PI section of my non-HRM and they were a little cheaper as well, I think BobW also used some Xicons with good results in one thread here

[marcos]

I have actually done the very same thing, using Xicons in the PI, with good results.But I preferred the 6 PS in the preamp.Trust your ears folks

Maybe it was Bob-I with the Xicons all I remember is it was Bob somebody

[dogears]

Don't do it. There is no possible reason to ever consider this kit with its complete utter inaccuracy. Do Brownnote or Ceriatone....

Yep, Bob-I.... too many Bob's to keep track of.

I like the Xicon's but they're very different than the 6PS, more aggressive in the mids which works in some context. For true Dumble smoothness 6PS in the pre are the way to go. The PI is less sensitive to these differences. For a nice aggressive Rock tone go with Xicon or 715 (I prefer Xicon) but it won't be Dumble.

The Halle is NOT a Dumble...

Thanks for the info guys. I do relize it's not a true dumble but for $650 it's much more reasonable than the $2000 i'll be spending on the Ceriatone or brownote amps. I actually have a Ceriatone OTS which i moddified it sounds great but i need a backup amp and i want a cheaper amp i can play around with (circuit wise)

I think i'm still going to do the Halle build with my tonestack and see how i like it, from there i will start experimenting with more "true" dumble values (with the exception of my custom tone stack) and use the 6PS caps that were reccommended.

As i said im not looking for a "true" or "perfect" dumble but a good platform to design my own amp on. I do not wish for this to be a clone of any sort just a good dumble vibe with what my ear likes the best. I have a pretty small budget which will mostly be gone from the kit, and hopefully i'll have enough money for some KT-88 power tubes and some trannys to support them and the caps i need
