I'd been using NOS Phillips ECG's in my Cary SLM-100's for a long time, and couldn't bare the thought of changing to new production anything. That was until I found out what the prices had done on matched octets of ANYTHING NOS. Almost impossible to find now anyway! I bought a matched octet of the latest Winged 'C' 6550's from Upscale, and was very presently surprised. They are actually more open than the Phillips. Now- IF someone could only create a 6SN7 that could even come close to the TungSol VT-231 round plate(driver) and Sylvania 6SN7W tallboys(phase splitter) I'm using........Well, I hope my hearing goes before they do! Maybe I should start playing the lottery.
