BTW-rick don't do 1/4 W unless it is SMD and there it is actually less so :

Rick don't do 1/4 watt

I will have a BOM done before friday. What W are you using if not 1/4? Also, why not 1/4?

personal fetish and no other reason.Maybe it is the wimp factor of tiny little parts

0.4W,0.5W but no 0.25 watt if I can help it and since swearing off SMD (RoHs
rolleyes.gif
) have no more need to do chip resistors so................

Just use 1watt all around!

Except of course that 1....

Have you seen the size of the holes on the PCB? You'll be pushing it with large wattage resistors, why not just go with the 0.4W Jan suggests? I see no value in using 1 watters, no value at all.

It was ment to be a joke. I am actually going to go with 1/4watt.

.....but,but but Mikey ! They come in such cool colors man

I like and will stick to my "manly" 1/2 watters and when I need to bump up in wattage it is straight to power tabs with bolt on heat sinks

tip-unless you get great air flow no way you get 1W dissapation from a 1W resistor in a closed chassis unassisted.even those pretty metal can resistors are only good at the full rating when cranked down to a heat sink (the chassis

has nothing to do with anything but felt like posting it anyway

I'm sure I speak for many others --- we anxiously look forward to your post, to compare with the "whats" and "wheres" of our own lists.

Let the debates begin!

I've started to build the board, and listen to what PinkFloyd says, those resistor holes are small.

Your gonna listen to a guy that beat the crap out of two BUF634 buffers with a freakin' hammer on a cement floor ? THEN BRAGGED ABOUT IT !!!!!

You are a very brave or very foolish human

What wattage 0.22 ohm resistors would be suitable? In the schematic it looks like alot of power is going to go through them...

1W will work. If you look at the schematics the 4.7ohm is 4W and the 3k9 is 1W. They are in the same power line and the holes on those are just like all others so if someone wanted they could populate this board with 1W resistors.

ok next question...where the heck can you find 10 pF film caps?
