Hi all-
I have a question on heat sinks for a mini-A / A-30.
After looking long and hard @ the A-30's horizontal heat sinks I "think" these mounted vertically would work.
I am looking for educated guesses to confirm or deny.
The ones I have are rated @ .5c/w for a 3" section. Mine are 8.5" tall.
I will post a few pics.

OK, rule of thumb #1 says double the height, divide by 1,4 which gets us a 6" section rated @ .35K/W. Rule of thumb #2 says after 6" dont expect much more, so conservatively I'd say 8.5" piece should get you .30K/W, maybe .25K/W. Aleph 30 burns 100W/ch, so one sink per channel should give you a temperature rise of some 30C above ambient, which seems acceptable, depending on how hot it gets where you live .
Take

You'd be amazed at what plating shops throw away as scrap or junk.
Rgr that and thanks. I thought they would but was hoping for a second opinion. If I have to I will turn down the bias a tad and listen.
I'm going to double that for the Krell KSA-50 clone.
