Matching and Selecting Options for Preamp Tubes
Matching in Pairs for preamp tubes means that two tubes show identical gain, hence, four characteristically identical systems.
This matching method includes our Balance-Selection. We highly recommend this matching method for hi-fi systems.
Premium Selected/Highgrade tubes are guaranteed for a period of 12 months (according to terms of warranties)
for the quality criteria mentioned above.
