At the time I was thinking about buying a ARC LS2 pre-amp and replacing the tube (tube ECC 83). I ended up changing my plans. However I replaced the Tube in my DAC, (12AX 7)with a Mullard and was not that impressed. Thought about trying a Telefunkin model. That's were I got confused over the Gold Pins, the Diamond and the age and region of were the tube came from. Is there a certain country that is noted for there tubes? Russia, Germany? Thanks for all the help
Tesla Tubes
I am new to tubes. Are Tesla tubes any good, Or does it depend on the tube? Are older tubes better than the newer ones? What does the term "Golden pins" stand for? And Diamond stamp? Thanks a Million!
