Congratulations on y our choice of the SINGLE RECTIFIER 50 Series 2 amplifi er . Y ou hav e purchased a handbuilt instrument of the fi nest quality and craftsmanship .
P A GE 2 FRONT PANEL: First f amiliarize y ourself with the lay out of the F ront P anel. Ne xt, remov e the f oots witch from the transpor t pouch located inside the cabinet ( combo ) and connect it to the proper jack. RECT -O-VERB Series 2 amplifi ers use a DIN jack located on the underside of the chassis’ s outer edge.
Each channel of your amplifi er contains diff erent modes of operation that ma y be selected depending on your application. In this w a y you ma y decide to use the channels for their most ob vious sounds or with the fl ic k of a s witch - inv er t the channels f or the opposite sound style .
P A GE 4 MODERN: Aggressiv e. This is the word that best describes the menacing po wer of the RECT -OS ’ most rebellious of all modes . RECT -OS ’ most rebellious of all modes.
2.) GAIN - In conjunction with the T one Controls - Basically , a simple r ule applies...as the Gain is increased the T one control str ing has less and less eff ect on the signal until at 5:00 the signal is so saturated that you are getting mostly Gain and v er y little T one .
As Channel 1’ s MIDDLE Control is sw ept past 1:00, it quic kly starts to add gain in these midrange frequencies adding cut and punch. As the top end of the control is reached, ( 3:00 - 5:00 ) it be.
MASTER: This control is the master f eed from the end of the pre-amp to the dr iv er stage and the Eff ects Loop . As you can see each Channel is fi tted with its own MASTER Control, enabling the two channels relative volumes to be matched regardless of their e xtremely diff erent sound styles and gain signatures.
SOLO: This control can only be activated if the correct Footswitch is connected to the F oots witch DIN jack. SOLO is an additional fi nal output lev el control wired in parallel with the OUTPUT Control. It is capable of a setting abov e that of the OUTPUT Control and can not be set below .
SLA VE OUT : This 1/4” jack provides a signal der iv ed from the speak er jack. P erf ect f or using the RECT -O 50 as a master pre- amp , or additional po wer amps ma y be connected f or more po wer when needed. Some pla yers use this to derive an FX Send Signal and go to other amps f or their wet sound.
P A GE 10 BIAS SELECT : (Contin ued) chording or soloing, to an all out high gain cr unch or lead sound. Play ers that use mostly these types of sounds ma y prefer the EL34 clip to the 6L6’ s that come standard in the new RECT -O 50 amplifi ers.
CHANNEL SELECT : This switch simply allows you to s witch between the two channels (CHANNEL 1 and CHANNEL 2) without using the Channel Select F oots witch or , when one is not av ailable . T o use the foots witch howe v er , the Channel Select switch m ust be in the (up) position.

P A GE 17 SPEAKER IMPED ANCE MA TCHING & HOOK-UP GUIDE: IMPED ANCE: Wiring up speak ers to pro vide the most eff ectiv e load and making sure that all of them are in phase will help in creating the best sound possib le.
P A GE 18 SPEAKER IMPED ANCE MA TCHING & HOOK-UP GUIDE: (Continued) P ARALLEL: When wir ing in parallel, the resistance of the speak ers decreases. T wo 8 ohm speakers wired in ( hook ed-up ) P arallel results in a 4 ohm load. It’ s easy to calculate the eff ect of a resistiv e load when all the speakers are all the same resistance .

P A GE 23 TUBE NOISE & MICROPHONICS: Y ou ma y occasionally exp erience some f or m of tube noise or microphon ics. Cer tainly no cause f or alar m, this quirky behavior comes with the terr itor y and the T one.
P A GE 24 DIA GNOSING PRE-AMP TUBE PROBLEMS: Because your amplifi er is an all tube design, it is quite possible that y ou will at some point e xperience minor pre-amp tube noise . Rest assured - this is no cause f or alarm and y ou can tak e care of the problem yourself in a matter of minutes b y simply s wapping tubes .

P A GE 26 BIAS ADJUSTMENT : (Contin ued) control grids. V oltage and current are NO T the same. Current is the AMOUNT of electricity , the “quantity” — and is measured in amperes . V oltage is the degree of electric charge — lik e the “pressure” to use the old water analogy .
P A GE 27 BIAS ADJUSTMENT : (Contin ued) Again, this has some mer it .. but it’ s still not as good as using tubes that are matched in the fi rst place because compensating f or the mis-match causes the push-pull circuit itself to become unbalanced.
P A GE 28 ON TRIODES, PENT ODES & IRISHMEN: With apologies to F r iends and Relativ es from the Emerald Isle - who will mak e their appearance soon enough - the humor which f ollows is dedicated to the memories of Spec McA uliff and F ae (Rafael) McNally , two of the T r ue Greats .
P A GE 29 ON TRIODES, PENT ODES & IRISHMEN: (Continued) Thus a diode tube - one with a cathode and an anode - is mostly used to rectify alter nating current into direct current b y passing it without restriction, but in one direction only .
P A GE 30 PENT ODES: (Contin ued) Thus the proper cocktail w aitress - visible through the louv ers - is scantily clad so as to be all the more eff ective at reinf orcing the attractiv e infl uence of her bar and b y being located in between the door and the bar , she ser v es as bait to lure customers past the door’ s negative infl uence.
