Sorry for double posting. I am a new member, posted once over the "new member" side. I am 56, just start playing, no big dream, for fun only. I bought a set of minty 1974 v4b with V6-b cab on the weekend from a 71 yrs old musician. He already updated the filter cap with F&T cap, a new set of JJ 6l6, preamp tubes are original. He told me 6l6 will work just fine. I am not after the big sound, should I switch it back to 7027a? what is your thought? Cheers.
