Does this look like enough heatsink?

Destroyer OS. · 29th January 2007, 04:05 AM

The chips are bolted to the plate you see with RCAs and binding posts.

It is just cheap sheet metal from Ace.

Should I some how add more heatsink?

It does get hot with only under a minute of play time. Not so hot I can not touch it, but hot.

This is sort of project use everything laying around.

Oh yeah it is a 330va 25v transformer being used, into 8 ohm speakers.

Not a chance in hell....
A nice 2.5C/W heatsink may set you back $5....

What chip? Is that 25v single supply or is it two 25v rails?

Everything lasts longer and works better at lower temperatures. If it gets any more than slightly warm, it's too hot. Surplus heat sinks are cheap. Get a couple of them.

I'm glad I upgraded my heatsinks... we had a 40C day in the week... went to feel the sinks... they were HAWT...

I added some heat sinks but I fear they are not enough.

Damnit I want this done in a day. Where can I buy local heatsinks?

25v per channel before recitifcation. 3875 chips

If you can touch it for 10 secs or more (really touch, not touch-and-go) you're OK. It means <50 degrees heatsink.

Nice butch project

You got a perfect opportunity there to bolt something to the outside... go to a scrap yard and look for a piece of copper or something...heck...even bonding some 1/2" copper tubing pieces vertically from the Home Depot would help.

I was thinking that mixing metal powder with regular silicone caulk would make a decent DIY adhesive for a "heatsink"...you know...in the spirit of the butch look and all
