tswisla,
My 6EM7 are the original ones that came with the amplifier, GE or RCA. Not exactly sure (I’m currently out of town). Which ever they are they’ve been fine and trouble free. The 6EM7 are very long lasting tubes. Mine are 10 years old. I had them tested about 2 years ago and they still tested as new. tswisla you’ll have no worries with the Frankensteins. They have been rock solid reliable while providing superb sound quality. You have the latest MK III model which is probably even better than my MK II.
At this early stage you have already recognized that the Frankenstein and Soul Supremes are a Splendid pairing. All you have to do is just enjoy your music and connect with it. Your sound will continue to improve as the amplifier’s transformers (and various parts) accumulate hours of use/burn-in. Same process is applicable to the speakers. I strongly suspect that your appreciation of your audio system with grow as time goes by.
