    Looks very good! I'm sure it sounds good as well. Those Mundorf caps are very good, and with the Sonicaps it makes it even greater.

    Taken from a recent Audioholics reply regarding "Club Polk" and Polk speakers:
    "I'm yet to hear a Polk speaker that merits more than a sentence and 60 seconds discussion." :\
    My response is: If you need 60 seconds to respond in one sentence, you probably should't be evaluating Polk speakers.....

    Yeah, it is a "double pleasure" to build your own amp. first: you choose the quality of the parts you want to use and second is the feeling to know that it is "unique". it feels good!!!:cheesygrin:

    Is that peel and stick adhesive on the bottom of those filter cap?If so thats an interesting way of keeping a two pin cap stable when PC board mounting.

    He recommends it

    Scroll down a bit and he explains it. I think it's a nice, simple idea.

    yes it is. the Mundorf came like that from company! But since I did the top of capacitors on the chassis, I had to put silicone to hold them (stronger).
    I find it very clever but "only" for those "big and wide" caps. I do not think it will do much on the small and slim caps.

    I believe it. I recapped my am and preamp a couple of months ago - the filter caps. Still sounded dull. I then got off my billfold and replaced the filter caps and that change created a much better sounding system. Tighter bass as you explained but also more musical. Just brought my amp back to life.

    What I noticed Before upgrade the caps, the dc offset was at 6mV L and 7mV R. I had to bring it down to 00.4mv in each channel. I also had to adjust the bias.
