Man, i'll tell one thing,this main board is a mess!Apparently this board was upgraded from a 9-160-03 to a 9-160-05?Where they're any service bulletins issued for these sets?Here's what i found so far:

RX3363: cut out?
RX3366: cut out?
RX3367: cut out?
RX3364: looks like it was never installed (not really sure.)
A .33ohm 3 watt resistor in C3315's spot?
A .18 ohm 3 watt resistor in L3302's spot?
R3201: vaporized!Have no clue what it was!
I'm assuming that the TO-3 installed on the center heatsink is the horiz.output?They mangled that too when they replaced it!Didn't even bother to clean off the old heatsink grease,they just added to it!
Going to need all the help i can get on this one guy's!

Cheers!
