There are octal adapter with all pin out, with your amp/preamp switch off,plug the adapter and plug your tube on top of the adapter.Use alligator clip on your multimeter's volt AC and clip them the pin 7 & 8.switch on your equipment and if the reading is about 6.3 volts?that is correct.but if the reading is not 6.3~ ,switch off and turn your meter to dc volts.Switch off your gear before removing those clips.6.0 to 6.7 is normal for tubes with 6.3 filament.
6SN7 tube question
Hello,
I need to replace the tubes in my Rogue 99 line preamp, which uses the 6SN7 tube. I was looking at an online seller who offers the following options with an affordably priced 6SN7 for a few dollars extra:
1. Balanced Triodes
2. High Gain
3. Low Noise and Microphonics
4. Matching
Options 3 and 4 seem most desirable for a preamp. My question is whether it is worth the extra few dollars (approx. $6 per tube) or is it just a pure marketing ploy to get suckers like me to drop more dough?
