Commodore 64

I'm building a Bassman inspired build based on the 5E3 PCB from ppwatt.com. Schematic, Layout, and other discussion of this build are at: http://www.45watt.com/node/15473#comment-146527
This build is based on 2 6v6 tubes, and there is some departure from teh 5F6A circuit. I put together a Mouser order. Please note that there's enough of each part for 2 builds:
Choke, Mosfets, Resistors, electrolytics, mica caps, power plug, fuseholder, switches, pilot lamps, pcb standoffs and screws, and OT blade connectors are saved to Mouser order:

Or enter this code in your project page: 5167372296
I ordered the coupling caps, pots, tag strips, tubes, and tube sockets from AES (and a gallon of "Tolex Glue") AES also sells a plug with a fuseholer, part #: P-SP2-500 . I didn't see that when I made my order so I ordered a separate plug and fuse holder from Mouser. Again, I ordered enough parts for 2 of these builds, but this parts list should help.

Note that the schematic recommends 8k primary impedance on the OT, but the one I ordered is 6.6k. Not sure what the implications of this will be yet.
