I am trying to find out what the range is concerning "bias rating" numbers for stock EL34 tubes in Friedman BE 100 amps. If everyone who owns one could please take a few minutes to read the number written on top of the four EL34 power tubes in their BE 100 and post them, I would sure appreciate knowing the results. If the tubes are original then they came from ARS and the number will be written on the top of the tubes in felt pen. It will take less than 3 minutes and will be very helpful.
Please do not post what setting to bias the amp at, that is something entirely different.
Thanks.
