Time to pick up the beta 22 project which got pending for years. Most of the websites I collected at that moment are broken now. Any recommendation on cables for both power and the cables inside the amp?  Silver wire is also welcome:).   and where do you guys buy covers for toroidal...

someone offers me two mono EMT 139A plus power supply for 5000euro. I would like to use them as stereo phono amp for my EMT 930st. How is this setup? anyone has experience with EMT 139A? the last one sold on ebay was only like 1200 euro, is 5000 euro too expensive for two EMT 139A? Thanks.

my cat likes to bite on my glasses and sit on my amp, maybe it is warm there.

so far, all my components are default from the glass jar audio kit. I did not notice there is a capacitor upgrade option in the order form, otherwise for only 20 dollar more, i will really consider it. (IPodPJ, looks like you have the capacitors upgrade ) I am thinking about the DACT attenuator...

I got it, thanks to clear this out. Quote: Originally Posted by Beefy True, but the message is pretty clear...... boutique parts are not necessary at all. The UHE are great power supply caps, so I personally see little need to switch them out.

Oos, that thread did not go well...... Quote: Originally Posted by johnwmclean This thread might help you, it’s all been discussed before... http://www.head-fi.org/forums/f6/nee...22-amp-338879/

Hi all, I am wondering if it is worthy to upgrade the capacitors on beta22. I am using Nichicon HE series now, upgrading them to KZ (muse) series does not cost much, but just need some work to replace them. have any body done the capacitor upgrade and have noticeable improvement? any information...

any store suggestion in Boston area?

+6dB means the gain is double. in log scale, "+" is "x" in linear scale, from (x)db=20*log(Y), for 6 db, Y=2.

for the resistors, here is his email to me: Resistors are vishay 1% 100ppm. Some of them are other brands like vitrohm or royalohm also 1% 100ppm. Have also attenuators with vishay/dale r55 resistors (see pic).

god, i think the turn around time is a little bit too long for this thing.

while i am building the beta 22, i just want to confirm the value of C1, is C1 always 33pF no matter what gain you use? since C1 is on the feedback path and i guess it is for the compensation,so I thought it will be depend on the gain. But it seems only C2-C5 changes with different gain. so...

wow, seems this thing is attractive. Only waiting for the impression now.

hope you guys can get the item soon then let us know about your impression. I really want to put this sexy pot in my build
