I was always very skeptical about selected tubes. I mean, how much different could it be from the non selected tube from a reputable manufacturer (we are not talking about Chinese tubes here). I got 4 Telefunken 12ax7 Selected Tubes when I purchased my McIntosh 275. I plugged then in, and they sounded very nice. Then I looked up the price of the tubes and they were going for $225 each!!! “This is crazy” I thought. How can a tube cost so much compared to the non-selected version that you can buy for ~$40 on a good day. Given that these were NOS and everything, but come on. So I put them away. Later on I decided to sell them – $900 is a lot of money for 4 small tubes.

Mobile rated meant not only rugged and hardy in the face of repeated on-off cycles, just as stated, but also capable of performing under extreme fluctuations of filament voltage as supplied by Jeep or halftrack battery, etc. under field conditions, I believe the spec called for reliable operation w/in range exceeding 5V to 7.6V on the heater! ” Read

life. The only flaw it might have would be on bright systems it tends
to have a happy high end, but I can live with it”. Read
“Beautiful punch/dynamics, with the leading edge of the Telefunken’s without the “etch”. The body of the harmonic is not quite as full as the long plate Mullard’s/Amperex’s but more body then the Telefunken’s.” Read
