[quote user="decoud"]Looking for a reliable one myself: a capacitor just failed. Similarly for Electrocube 950s which are obscenely priced in low quantities direct, and not on the ground this part of the world. [/quote]Really? Did you form it before...

Rather than using a single can my builder made a bank of 470uf units, one of which failed. I thought I'd replace the entire bank, for simplicity. ...

Here is a stupid need of DIY audio level. As many of you know am big lover of Nichicon electrolytic capacitors, even their lowers grade sounds right to me and never made to think about anything better. Still the Nichicon never stopped to surprise me....

Decoud (and others), where do you source big Nichicon caps, pref. in EU?I'm slowly preparing to attack a Staxquiades - a mastodont Milq inspiredamp to power Stax headphones (PP 6E5 DC to PP 2A3/300B/EL34). I need 10.000uF/500V and 10.000/350V caps.Mo...

Of course you know,Romy, but others may not know/remember that Nichicon have always had great specs, and years ago they were a "secret weapon" in the high end.But lots of the DIY guys are computer geeks in their day jobs, and The Story is that Nichic...

With all magnificence of the new 924++ DAC it have entered the second week of the Nichicon KZ playbook. It was completely predictable and highly expected and now the DAC sound very funny.
The bass is fully developed already. The DA924 always was phe...

Jarek, the best source for these big Nichicon electrolytics that I could find was Digikey. They were substantially less expensive than other sources that I tried but do ship from the US which is an added freight cost. I purchased these a couple of ...

[quote user="Paul S"]Where MODERN electrolytics shine is specifically for PS use[/quote]
I have to agree with it. Furthermore when I agree I back up my word with actions. This morning right after I posted my post above I opened the amps and ...

"Do not use plastic caps ... but go for a tandem of electrolytics Nichicons with active biasing."
Hi Romy,
Please excuse my ignorance. Can you please clarify what you mean by "active biasing" -- in relation to the caps?
I'm thinking to get...

… but there is no one to ask how mater it is…
[quote user="hagtech"] Seems to me a small film cap added to a large electrolytic solves most of the sonic issues people complain about re the large caps.[/quote]
Hm, I do not know. I think if good caps...

As usual, I am hurrying to do something else as I write.Romy, although I think it is too early in the process for final judgements, I do continue to wonder if a long path through an electrical storm, from the driver plate to the DHT grid, is perhaps ...

Hi Paul,My question was of cause about my phonostage based on EAR834p and "End Of Live" modification with air capacitors and LCLC + 0A2 power supply.A couple weeks before I increase the second stage ECC83 cathode capacitor value to 43400uF (Kaisei no...

I ripped my Cd player (to old to mention ) output stage and replaced it with SS J-fet phono preamp .I took RIaa components out .The dac puts out only 20mV so the MM stage with separate PSU and discrete J-fet regulators seems adequte for the job. Whol...

That suck, it was two days as my playback shine at full glory and then my bass amps blew up. It has heavy noise from one channel and sounded like it self-arouses like crazy. It turned out the one of PS large caps got burned and stopped to filtrate th...

Paul, I'm not rushing to the breadboard. I'm trying to visualize if Romy's constraintscan be satisfied. I have to gather more data on GU81 to think of doing anything.How linear it is?? Perhaps this tube is an audio no-go as you've mentioned?Going to ...

[quote user="Paul S"]N-Set, at some point I wil try to actually pay attention. In the meantime, does effective RC change with signal/gain in this situation? If so, it might also appear to "change the slope".[/quote]Paul, the FR does not seem to dep...

It is really a seldom thing in audio – when people ask questions afar they do own homework and demonstrate understating and own thinking on the subject.

Though my new updated Bidat is too fresh but considering that I know very well how the Nichicon KZ progress with sound I think I can make some preliminary observations about the revised sound of my Bidat.
The change was not a large, less than I expe...

From another perspective it has film capacitors and the non-polarized Nichicon Muse caps. They take up-to to 30 days to burn-in. So, it might be just too fresh. I would not say that it kills everything – it is just a very-very slightly brighter, enou...

Measet, I will try to find a photo and the schematic as you requested, but it may be a while before I can locate them. Plus, we are still digging out from Hurricane Irma down here. As I recall, I beefed up the raw D.C. supply and then used an LM317 r...

A week passed since I updated my Lavry-924, what a sound! If before the DA924 was just the most advanced and the most interestingly designed multibit with excellent sound then now it is becoming the most advanced and the most interestingly sounding D...

Bidat, for whatever reason is remarkably sensitive to electricity, probably it is more sensitive than any other my priced of equipment. What however is ugly is that during different time, during the different problem with electricity the different me...

Romy,I have rebuilt my phonostage (the pictures after update are added to Picasa):1. Fixed filament. Now a ripple about 1mV (unmeasured by my Fluke). The filter is: C-L-C-L-C
