Black Gates Going for Nuts $$$?

[merlin el mago]

Why not try some HV caps & bypass with Russian Ky40 caps Merlin ? You might get something similar. I played with the Ky40 & there’s some BG sound to it. Another option, is to look for low value BG like 10uf HV caps & parallel them with other caps. I bought a bunch of 250v 10uf caps from Micheal Percy, not sure if they still have stock.

I used Jensen PIO bypassing big lytic caps in PSU and don't like it. I like the 1/10 value of Auricaps bypassing the big lytics in HV PSU.

Try it on the circuit side instead Merlin. Psu side big oil caps works with small film bypass but strangely not the other way round like you experienced.

Cheers

I don't like oil caps (mkp in oil or pio) in HV PSU, because lack of bass.

 

[sumotan]

Not asking you to use oil caps Merlin, just saying that film caps as bypass works with oil caps & not the other way round.

 

[merlin el mago]

OK thanks.

100% it's F&T.

Luke, you're very astute. I wonder why no one else has picked up on that. How can a tiny British HiFi brand make money from a product that a huge multinational couldn't?

I can't help but think that they will get a big run of a few values that will sit on shelves for years. I prefer to buy fresh caps.

What about:

CDE 380LX
Vishay / BC
UCC KXL
EPCOS B43601

Or, what’s the best HV electrolytic currently available for mortals?

 

[merlin el mago]

About the polyprop tubecaps there is no doubt. Have a bunch of F&T Joule caps 20/750v and they sound pretty much identical. Look identical too.

As for other makes...have a few high voltage Rifa, hesitate to recommend them. Similarly with Felsic, but unlike the Rifa these have at least an excellent midrange. Also have some Kendeil which are just horrible.

Perhaps Siemens/Epcos/TDK are worth a try.

Just arrived Kemet 820uF 550V, attached pics and datasheet.

Thats about what my car is worth Actually now that I think about it, I would rather have the caps.

It will be interesting if you share an opinion. What are you comparing those to?

My experience with low voltage caps from the same series was deeply negative, but that means nothing.

 

[merlin el mago]

BG, Elna Cerafine. I will let you know how performs.

 

[ErikdeBest]

The Kemets used by Rod Coleman!?

Rod Kemet ALS61 820µF 550V caps.

Mine Kemet ALS60A821KF550 820uF 550V.

Not the same serie but the same specs.

 

[ErikdeBest]

thanks for replying, I didnt notice there was a difference?! Looking back at Rods posts, in one he writes about the ALS60, in the other about the ALS61. I keep both in mind for future projects

HV Kemet are very very good.

For LV I used Jensen 4 pole but I like more the BG and second Mundorf Mlytic AG+

For HV the best are BG, Elna Cerafine aren't bad but can't compare vs BG, still searching the substitute.

Hi , for LV power supplies bank I use the Supertech 4TTN (4 taps) with excellent sonic results across the audio spectrum. They are musical and have guts in current drain (4700uf /63V ---> 8A rms @120Hz ripple current). I have already supplied a big bunch of them, enough to turn them heritage to my kids

Andy what's the ESR?
