Tested With Roetest V10 By GAIN NOS/NIB The
gain is the parameter that mostly affect what we hear from a
preamp/amp. Using tubes with the same gain lead to same sound level from
each channel. We removed tubes close to inferior and superior limits. For tubes matched by curves or by Ip and Gm please see our other listings. The tubes passed all quality checks - vacuum, shorts, leakage, heater current etc. |
