Now doesn't that feel good?

I designed them myself, including custom machining done to the Conrad heatsinks.
If you want to replicate them I can PM you the front panel express files, which should also work at their parent company which is based in Germany (cheaper shipping for you)

Thanks for the info, I have something very similar designed for a future project, if it were available on the shelf would be much cheaper.

Yeah, with heatsinks it was about $1400 for both cases, not including the guts.

Sweet little amp case there!

I'd change and increase the gauge of the ground wires on those caps by a WHOLE LOT. Like 10ga would suit me fine.

Also take your ground wires and somehow in that design create a very short "tab" off the center point to connect to, rather than spreading the connections, or having any connections elsewhere, including on the tabs of the caps... assuming you continue with this physical connection method, that's how I'd work it.

Excellent Byrd, glad its working. As we discussed on the other forum, and despite what the naysayers say, your amp was not having an oscillation problem. Things would have smoked if you did. As I told you, Peter Daniels said up to 12 inches with the standard F-5 would be no problem. This wasnt directed to a turbo version, but the F-5 is also a very wide bandwidth amp. Easy fix, glad its working properly.

Yes, I didn't think it was going to oscillate, since I built my first F5 this same way.
