Rogue 150
I have tried several NOS tubes in my 150 currently I am using GE 6550
about $175 a pair the rest of the tubes are Mullard NOS
Since I live in Houston I buy them from Tejas Tubes locally
I have tried the reissue Gold Lion KT88, I think for the money the Shuguang
88 works very well
Bat-Rogue
I have a bat 3ix and rogue m150 mono-block combo they work very well together. tried several other preamps
currently i am using the 3ix with bryston 4bsst
