OK. 1 watt 500 volt replacement resistors in the board. So what I have left is actually getting the tubes (6922's x4), getting the rack box, and some wire I need to run jumpers to the switches (probably 22 gauge in 6 colors), wire to hookup the XLRs (Belden 8451), and wire the for AC mains. Probaby 18 or 20 gauge since this should never draw more than 2 amps, and when warm, should only draw 750 milliwatts total.
