I've noticed for a while now that my phono stage sounds less "splashy" since I swapped in the V-Caps, and the truth is, I kind of miss the splash, as it carried through to tonal colors, and it was low enough that it mostly made the Music "more colorf...

FYI: Talked to a vintage specialist/repairman about old dried caps. Compressed sound and lack of space are the two things he mentioned straight away....

Good people,Has anybody tried CCS heating of the tubes here?That idea +/- makes sense to me (more with DHT though)and wanted to try it, but perhaps somebody has already been there? I'm thinking of 3 individual LT337 past the last reservouar caps, CCS...

...but it will take me N-years and I'm in EU :)I could make some preliminary steps this Easter, talk to my winders about transformers etc.I'm for sure missing the FW and out put cores (AMCC800A will not support 120H at 300mA, low DCR), but getting ma...

At those small values mouser, didgikey etc should be ok, no?Any reasoning behind such a approach aprt fro aviability?Also ROmy has sunstancial capacitance at 15000u etc, do youuse 30 caps in a bank?...
|

OK, good luck with your experiments. Be advised however that if you use capacitors for high-pass speaker lever crossovers then those caps need to be aged. The amplitude of this effect wary from cap to cap but all of them in one way or other would ne...

I have a pair of the english crossovers with russian caps i dopn't need willing tgo sell for half price if you are in the US and waNT THEM. They hAVE A CLEANER SDOUND THAN MY TWO SETS OF ORIGINAL CROSSOVERS but not as roman tic.am using my trinnov al...

I'm afraid I lack the savvy and/or the patience to figure out from those links how to buy just two matched Electrocube 950Ds, since all the distributors seem to be geared to industrial purchasing protocols.But if someone wants to send me a match...

An unprecedented three straight sessions now with no "power problems", including hot weekday and weekend listening. This newfound stability happens to coincide with the bigger caps. Although I refuse to draw any conclusions about this...

Just 1 attempt to explain dumb questions, then a sleeping pill:OK, mistook the interstage couplers for speaker level caps, as though all channels were single stage, and from there projected the "active" band pass at speaker level (wrong turn at ...

Romy, isn't this the first time you have tried the film caps for PS and the "ALL-NEW" "SUPER-SOFT" diode bridge? I would certainly go back to known quantities before I did or un-did anything serious. Not that I always follo...

…as the similar channel on the left amps play perfectly fine and very differently. I did switch the S2 drivers and it had no result. The most funny is that the right channel has very plastic horn honk – where the hell THAT come from? I cannot stress ...

has supposedly very nice Obbligato line of film HV caps . I personally bypass Solens with vit. Q and they are OK to me but for you it'll be probably summit of known what.Rgrds, W...

So it basically remains a hard-wired, series drive line, and also powered like a discrete monoblock amp? Do you mean to treat it like a single-stage channel?What are benefits of hard-wired mutual (one pot) source for tetrode and DHT filament/cathode...
|
|
The oversized Obbligato caps are installed and everything is looks like it will be when it will be done. I just need to in use some good 5-pin chasses-mount and on-cable-mount connectors abled to care over 3A that will bring filaments to the amp from...

[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 ...

[quote user="Paul S"]Anthony, it sounds like you have given a lot of thought to damping structural vibration. I was referring to the electro-magnetic fields thrown by transformers, and - based on my view of your perspective drawings - I was wonderi...

My stereo corrector (834P with air-vane caps) has a shorting switch across the two channels at the input. I suggest you incorporate the same.With it out of circuit I did indeed get that hum you refer to with the SPU Mono. Switching to short eliminate...

PS caps, of course...I'm guessing I'll have about .25/second to make my assessment...Any luck with the APS on the phono stages?Best regards,Paul ...

I am not sure who those people are. It might be Arthur Loesch or someone who cashes out on Arthur Loesch… it might be whoever and I have no idea about the credibility and seriousness of those people. I heard Arthur Loesch does not do Audio anymore, s...

Page 2 of the pdf you link to has four 2.0uf 950 caps: the writing is legible. So if anyone opens his unit and finds 935, well, it is an open and shut case......

Thanks for your reply Romy,The Johnson/RCA sockets had crossed my mind.The reason I'm looking for that specific type is that the contact surface of the pins is so much larger (much like with the Yamamoto).I could buy yamamoto's and not worry at all, ...

Yep, it is a lot of work and it might look like not well organized work but there is good part in all of it – when you will be do you will be done and you would never do it again. Practice shows that those custom tailored systems are made and then us...

The DC biasing of filtering caps was something that I was advocating for years but recently I was pointed out that German Avantgarde took it a bit further. I did not use this method but it goes sound interesting. Read the Avantgarde’s document, the p...

Yes, the crossover looks fancy :) More than that it does the job. The vacuum caps are only for the tweeter and the upper-mid beryllium. Still they are bridged with micas as they wont do much alone. Adding vacuum caps smoothens the transitions and sou...

...this is my first serious attempt to pack something into a case.[quote user="Paul S"]Nice looking unit, N-set. I also go out of my way to use part leads only in lieu of extra wire whenever possible. I really don't care what it "looks like" on thi...

I liked your previous post . A week ago I repaired old Telefunken tube radio (Single EL84 with array of alnico speakers ) with FM band and I'm listening to classical public radio for whole week. Not even once I had desire to turn on "big" system I'm ...

[quote user="Lx_"] Another example of cannot-measure-it-but-can-hear-it? [/quote]Oh, yes, there is plenty of it in the audio electricity world. It is not that “cannot-measure”, everything might be measured the problem is that we have no idea wha...
