Page 3: Operation: General
MATCHLESS amplifiers may be ordered as single, dual or quad speaker combos as well as separate head and cabinet configurations. A rack mount version of the C-30 head is also available. Speaker enclosures are available for use with rack mount amplifiers or as auxiliary cabinets for all combo amplifiers and amplifier heads. - Page 4 NOTE: MATCHLESS amplifiers are biased and should not be allowed to idle with no input signal for long periods of time. Use the STAND-BY function or shut the amplifier off during prolonged rest periods. 3. Tube type amplifiers are inherently sensitive to speaker impedance matching. This is due to the relationship of the internal resistance's of the output transformer, the output tubes, and the load they are required to drive.

Page 5: Switches And Indicators
SWITCHES AND INDICATORS POWER: OFF / ON This switch supplies power from the A.C. mains and is used to turn the amplifier switched as well as the A.C. outlet at the rear of the amplifier. The amplifier "MATCHLESS" status is indicated by the illumination of the logo on the front of the amplifier. - Page 6 ABOUT THE FUSE! Your MATCHLESS amplifier employs a line safety fuse for protection against damage. The line fuse offers protection against irregularities in an A.C. source, tube failure, component failure, severe overload to the output amplifier, and other conditions that prove unsafe or damaging to the amplifier.

Page 7: Preamplifier Section
About the PREAMPLIFIER SECTION Your MATCHLESS amplifier employs two very different tube types and circuit designs for the preamplifier channels giving each channel its own distinctive response and personality. This enhances the versatility of our "simplicity" of design philosophy. INSTRUMENT INPUTS: You MATCHLESS amplifier has two input channels or preamp paths. -

This switch is located at the rear of the amplifier and determines the overall output power of the amplifier. In the "HI" position all four output tubes are functioning and the amplifier is producing maximum power. C-30 amplifiers are conservatively rated turned off at thirty watts. -

To replace tubes remove the back panel of the amplifier. Preamplifier tubes usually have a twist-lock shield that must be removed before the tube can be removed from the chassis. (called a Output tubes and rectifier tubes employ either a spring and cap arrangement tube hat)
- Page 11 USE IN OTHER COUNTRIES: Your MATCHLESS amplifier is equipped with a multiple primary winding enabling the user to set the amplifier for various voltages and line frequencies available in foreign countries. This is an internal connection change and should be done by a qualified technician.

Should it become necessary to service your MATCHLESS product, please contact the factory. Specifications and prices are subject to change without notice or obligation. - Page 13 Country players are very fond of this combination. The overall smoothness of this design is wonderful. for power chord lovers too! Our four-ten cabinet can be used with C-30 or Clubman `35 amplifiers. Single speaker models produce a clean, rich, tone and perform well in almost any situation.
- Page 14 to the overall distorted tone. This is not the case with a master volume control which is primarily used to overdrive the preamplifier. At best it should be considered a tone unique unto itself. We feel that it is important to mention this fact as there are many who believe a master volume control will produce the same effect as turning the amp up to ten.
