PA G E 1 0 TUBE MAINTENANCE & MICROPHONICS: Y ou ma y occasionally e xperience some f orm of tube noise or microphonics. Cer tainly no cause for alarm, this quir ky behavior co mes with the terr itor y and the T one.
P AGE 11 DIA GNOSING PRE AMP TUBE PR OBLEMS: Because your amplifier is an all tube design, it is quite possible that you will at some point experience minor pre-amp tube no ise.
PA G E 1 2 SPEAKER IMPED ANCE MA TCHING & HOOK-UP GUIDE: IMPEDANCE: Wir ing up speak ers to provide the most eff ectiv e load and making sure that all of them are in phase will help in creating the b est sound possib le.

T wo 8 ohm speak ers wired in ( hooked-up ) P arallel results i n a 4 ohm load. It’ s easy to calculate the effect of a resistiv e load when all the speakers are all the same resistance .

PA G E 1 8 BIAS ADJUSTMENT: ( A continuing ser ies ...) NO TE: An ar ticle written b y Randall Smith that we thought you might find interesting. Here’ s a question we often hear : “Wh y doesn’t Mesa put bias adjustments in their amplifiers?” W ell, there’ s a shor t ans wer and a long ans wer to this question.
PA G E 1 9 BIAS ADJUSTMENT : (Continued) When you set the bias (whether it’ s by selecting the r ight resistors , as we do , or adjusting a trimmer — which is quicker) what y ou are doing is establishing the correct amount of idle CURRENT that flows through the power tubes.
PA G E 2 0 BIAS ADJUSTMENT: (Continued) Again, this has some mer it .. but it’ s still not as good as using tubes that are matched in the first place because compensatin g f or the mis-match causes the push-pull circuit itself to become unbalanced. T wo wrongs don’t really make a right.
PA G E 2 1 ON TRIODES, PENT ODES & IRISHMENN With apologies to Friends and Relatives from the Emerald Isle - who will make their appearance soon enough - the humor which f ollo ws is dedicated to the memor ies of Spec McAuliff and F ae (Raf ael) McNally , tw o of the T r ue Greats.
PA G E 2 2 ON TRIODES, PENT ODES & IRISHMENT: (Continued) Thus a diode tube - one with a cathode and an anode - is mostly used to rectify alter nating current into direct current by passing it without restriction, but in one direction only .
PA G E 2 3 PENT ODES: (Contin ued) stopping them. The influence of the plate tak es ov er and - being solid metal and of the highest positiv e attraction - it is at this final destination that the electrons congregate.
