KGSSHV, Balanced Dynahi Rev A and DynaFET board run
El_Doug replied to Lil Knight's topic in Do It Yourself
paypal will work just fine - read the previous page of this thread to see what the issue was with prepayments. once Lil' Knight has calculated the shipping costs, we can resend our payments -
using z-foils!

w00t! hope you post pics

KGSSHV, Balanced Dynahi Rev A and DynaFET board run
El_Doug replied to Lil Knight's topic in Do It Yourself
no one wants to produce them, and they wouldn't work for the pessante case anyway -
since I do not fully (read: at all) understand how the amp works, can anyone explain the specs required for the 5pf cap? 200v are impossible to come by anywhere on the web, so far as i can tell. better yet, a link to an in-stock alternative would be fantastic

if you missed out, I ordered an extra set that I almost assuredly won't be using (i only got it in case I somehow managed to break the first board). it's yours

is the LED in any way used for biasing, or simply for indication? if there is a required spec, what is it? also, the amp lists the 180 ohm resistors twice (mouser 660-MF1/2CC1820F) are the 1N914 diodes missing from the BOM, or are my gerber files really old? -

Shouldn't we use terminal blocks on the amp boards? Or are we supposed to solder those directly to the input/output? -
that's my very good friend's wife's name!

it wouldn't let me do it maybe because i'm using firefox 3? either way, it wasn't TOO much of a hassle to manually type in his paypal address -

it would make life easier if there was some way to copy/paste your paypal address (just a suggestion) -
Andy's experience proves it: the DIYT2 is a straightforward build that will maybe turn up a single error, that can be fixed within a few hours. Clearly, any newbie can tackle one, no sweat! On a more serious note, I can never tire of looking at these beautiful amps. Congrats on your build!

1) make more than 1 amp 2) just in case you manage to fry it, scorch it, lift traces, snap it in half.... -

I've never made an umbilical for this kind of voltage... any suggestions on wire? or can I use any old 600v teflon? -

El_Doug replied to Lil Knight's topic in Do It Yourself
but won't the teflon make the sound more neutral, while the gold adds lushness? edit: adding a "" to qualify the statement -

~10 days to get in on this - tell your friends! -
with the side-mount boards, this can all fit into a single 3U pessante
-
define standard? I'm going to be using angle brackets, and have plenty room given the boards are 4 inches across edit: oops, you were emphasizing the word "one" - yeah, it definitely requires two boxes

In for 2 sets of the KGSSHV, spreadsheet updated Thanks! -
In your estimation, how much more tweaking before have a version worthy of a pcb run that truly satisfies the "any intermediate builder will have no trouble" mantra? I wish I could help by prototyping all these things, but I fall into the "i know how to solder and use a multimeter only" club

you could have warned me, you bastard
