You know, the Cavalli Audio logo on the top of a 9" round cake would look awesome!



That's what I'm talkin' bout!

Put a piece of wood with a hole on the other side where the pin sticks out. Tighten the vise to push the pin out by the pushing force on the rod you inserted. If you can't find something suitable to use as a rod you can try and find a couple largish finishing nails with the appropriate diameter (cut off the heads and file ends flat) and just stick 2 down the hole.


Worked a treat - thanks! I used "common 3d" nails (37mm long, 2mm wide), cut to the appropriate length. Heatsinks are now all tapped and ready to go

I don't mind waiting a little longer.

I also still owe you for the case and input selector, (and case, resistors/caps, etc for the Corda Cross)...

I know you're good for it. I really want you to hear this amp though. I could loan you Sherwood's while I finish yours.

I shall not incur the wrath of Sherwood by pillaging his gear.

He hasn't been beating down my door for this. Although judging from how long he hung on to my proto - I think you might have a point.

I finished populating my hybrid amp boards today so with a little luck I'll get to work on air wiring the whole thing this week for some additional testing and chassis layout work.

Finishing up my chasis work in the next couple of hours, then powering up. This is probably the most blinged eXStata to date, so, pics in just a bit. About $400 in parts.
