I've got a couple of 4x12 cabs with Celestion v30s that I love - one is a Marshall 1960AV the other a Line6 spider valve A cab with v30s. I'm running them with a Marshall JVM 410 and JCM2000 TSL 100 - using some 1960s long plate Sylvania 12AX7 tubes in V1. Both sound remarkable with the Marshall preamp sections, but I have been running my Firehawk FX into the power amp section for both when I want to use other amplifier tones.
I want to buy a Helix, but I don't want to run them into the power amp section of the Marshall Amps, but rather to have a power amp that will drive one of the 4x12 cabs at 16ohms or both sides of a stereo cab at 8ohms each side.
What would be the ideal amp for this setup - I'm thinking that 2x50 would be more than sufficient for my purposes.
