    In my quest to get the best from my cornet phono amp i have changed to PP coupling caps from Mcap, seems a result so far.
    So now for the electrolytics, i need 4 10,000uF and 5 47uF. The 10,000 are supply smoothing, 2 on audio side and 2 on heater supplies. The 47's appear to be decoupling type thingys on the 375V valve side of things.
    So what have people found good for these use's, not BlackGate tho, over 100quid for a cap :yikes:. I have a few in mind but wanted other idea's.

    Next will be resistors, fairly settled on Vishay bulk foil, or maybe Caddocks.

    Ill be building a nicer enclosure aswell, but this means the RCA sockets wont be as close to the board as at present, maybe 4 -5 inches, so what cable?. Im thinking maybe some good shielded IC cable as i need to reduce any ingress of RFI with the longer runs. Does that make sense? If so a nice transparent cable is in order, but what cable can i buy unterminated without needing the national deficit in my wallet?

    Good quality IEC inlet? (internal power cable should be sorted soon :) )

    So what do all you cap fettlers recomend??;)

    Andy, I understand your dilemma, now here's the crux, by replacing with a cap of a Know better quality, will you actually get the result you are after :eek: :confused: :rolleyes: this afternoon, I proved this very point when changing a average cap for a top spec version, hum a step backward I feel, time and patients here and just trying more than just the usual suspects
    Have the same problemat the moment, The Belcanto has been sadly neglected of late, and has been down in the dumps, so's not to hurt it's feelings, I started to give it a spurse up :)

    [​IMG]

    Now, can I find a decent replacement for the 15K 50V sanwahs in there, so far NO, tried a lot of stuff, not as good, yet the specs are better, just goes to show, maybe some of these guys actually did some research when designing it :) man than I few I could mention. Wm

    o0o, shouldnt show pictures like that without a rateing:D

    You've grabbed the conclusion i got to Tone, but i dont mind chopping and changeing with parts that cost a few quid, as opposed to a few hundred - i feel a solitary life approaching if i went down that road;)

    I have also found the "so say" best to not perform as well as a lower class, in some situations. Guess it shows nowt is an absolute in musical tweakery:)

    Bybees

    0.02 ohm resistors packaged in a ceramic coating with fancy heat shrink on top.

    Sounds like bullshit, but many people say they work so there may well be something in it! Who knows I may try some one of these days.

    Nah, you got all wrong, it's just a empty case with a the crushed up remnants of a demag disc in there :eek:
    No, thats before I started, it's a little different now.
    I did little experiment with it earlier in the year, seperate all singing and dancing super reg's never connected supplies to the 5v dsp supply, hum a paul ransid special there, theroy says YEAH, but it practice all we were left with was a levinison, that levinsion would have been proud of :( ultra clean & smooth with oddles and oddles of hifi :SLEEP: however, I have adopted a different approach, oh this one rocks Wm

    Andy, It was, I'm not a great fan of O.E. filters shaffners and such like, they are better ways of doing (IMHO).

    yep, i tried a schafner on an amp an CDp, squashed dynamics on both.
    Much better to have clean supply in the first place me thinks.

    makeing a farnell order today, then for the internal signal hookup.
