Please note: Quantities are limited – Purchasing limits may apply. These tubes are not recommended for use in amps with plate voltages over 450 volts. It isn't uncommon for a grid leakage indication to appear when testing EL34s in certain tube testers. This does not indicate a failed condition for a guitar amplifier. Not all tube testers test for parameters relevant to a tube guitar amplifier.
