From the manual:
The Premier Five uses eleven vacuum tubes of three different types: one 5751 (V1), two 6FQ7 (V2 and V3) and eight EL34s (V5 through V11). Each type has been carefully chosen for its circuit application. It is well known that tubes of a given type vary sonically depending on the manufacturer. We have chosen the brands of tubes that we supply based on extensive auditioning of available brands. The choice of brand has been made solely on the basis of sonic performance and reliability without regard to either cost or prestige. We know of no vacuum tubes available which will improve the sonic performance of your Premier Five. Also, the tubes in your amplifier have been tempered by a controlled burn-in procedure that permits them to perform for a greatly extended period without sonic degradation. We anticipate one to two years of operation without degradation in normal use. We highly recommend that, when the time comes to replace the vacuum tubes, you purchase replacement tube sets from conrad-johnson design. The Premier Five has been designed to make tube replacement as simple as possible. Because the output tubes are individually biased, replacement tubes need not be matched pairs. No a-c balance adjustment is necessary. It is necessary to re-bias the amplifier when the output tubes are replaced. The Premier Five has built in bias indicators so that no instruments are required to make this adjustment.
