Okay, heres the deal. I have a Trace V4 which only runs in 4 or 8 Ohm, and I have a Henry 8x8 cab, which is 4 Ohm. I want to get an extention 115 or 118 (or 215 if I can afford it...). Any recommendations on the cab? It has to be 4 Ohms, which leads me to my next question. Who makes series 1/4 in speaker cables? I know that tubes can probabally take up to 100% difference in Ohms, but I'd rather put forth a little $ to avoid having to retube so soon.
