Far right hand side. Take off that metal plate. Preamp tubes are behind it.

Jackson DK2M
ESP LTD Viper-400
Jackson RR3
Gibson SG Voodoo
Washburn Acoustic

Peavey 6505 head.
Marshall JCM200 TSL100 head.
Vader 4x12.

Maxon OD9.
Boss NS-2.
Also here is the V patern for you

From right to left it goes-

V4 (Phase Inverter, use a BALANCED preamp tube in this postion) V3 (Effects Loop) V5 (Third Gain Stage) V2 (Second Gain Stage) V1 (First Gain Stage, put a Tung-Sol 12ax7 in this position)

So again from right to left

V4, V3, V5, V2, V1

Basically, put a Tung-Sol in V1, and put Chinese 9th Generation 12ax7 in the others.
