3W resistors

I noticed that Digikey no longer carries 3W Panasonic (or any other brand) resistors under 10ohms now - has anyone else been able to find a source for the bigger resistors needed to build an F3?

I've been looking at my boards lately but cannot find the ones I need.

The bubble gum blue resistors are still around at Digikey.
They are listed under Metal Film now, which I think has changed.

F3 PCB Boards

Peter, are you still looking for PCB board buyers for the f3 clone ? I'm in for two PS and two amps. I built Nelson's Pearl phono and it works great. I am ready for a new challenge. I have also been charmed by the sound of small tube amps driving Quad ESL's since I sold my M&A TVA-10 in the eighties....is this (finally) the solid state answer ?? Having heard a Yamaha B-1 way back when, color me intrigued.

By the way, where do you work at Boeing ? I'm in engineering in STL in Advanced Systems. I have been trying to get NP some GaN H-FETs from HRL, but no luck yet, (Imagine a F3-type with 200 watts power using one device per channel !). I'm still working it, but the price for the devices might be prohibitive until the Chevy Volt goes into production.
