Greetings all. I want to get some opinions on the best way to interface the impedances of this solid state preamp (left) output to the input stage of this EL-84 power amp. 12AX7 is the input stage. Everything works, but I'd like to make sure there aren't any 'Engineering problems' that might rear it's ugly head. I suppose the impedance should be matched? or not necessarily? Any thoughts?
