Where have you been Telam?
I have all NOS Pre-amp and Power Tubes in my Grandmiester now. I have 2 different matched sets of EL84s. I got the Tungsram set first and figured I would then try a set of Telams, since I have the single coil pickups on my Strat (not noiseless). The Tungsram set was very nice, but these Telam tubes are a notch above them for my setup. I have always trusted the Tubestore advice over the phone and on their website. These Telams are special if you have single coil pickups. IMO - NOS tubes have less noise concerns and with brighter highs and a deeper bass. The dirty channel on my amp has it's own attitude with no noise. I am using the JAN pre-amp 12AX7s.
