I was thinking of buying a PF-350 as a backup to my SVT CL in case a tube fails at a gig. The PF-350 is small, light weight and cheap. Tone and head room aside, will it give me a similar amount of volume as an SVT CL? I'm using a 410 HLF which at 4 ohms should allow the amp to put out the full 350 watts. Good backup or nay?
