The three position switch has two ON positions, one of which is used to ground the amplifier properly. One of the ON positions will yield the least hum or popping when the instrument is touched and this is the position that should be used. For your safety, we have incorporated a 3 wire line (mains) cable with a grounding lug. It is not advisable to remove the ground pin under any circumstances. If it is necessary to use the amp with the old two prong sockets, a suitable adaptor should be used. Much less noise and greatly reduced shock hazard exists when the amp is operated with the proper grounded receptacle. 15 The main speaker output jack #1 is a switching type and must be plugged into before the external speaker jack #2 becomes functional. The output impedance of these amplifiers is 4 ohms TOTAL. Other load impedances can be used with a sacrifice in performance. It is not recommended that less than a 2 ohm load be used on these amps to avoid undue loading of the output tubes. 16 The external speaker jack #2 is designed to allow use of additional speaker systems with the amp. This jack does not become operational until the main jack #1 has been connected to a speaker. It is advisable to note that we have provided additional power in this amp to drive more than one speaker system. This additional power could be more than one speaker system can handle. These and all other high power tube type amplifiers must be used in the proper manner to avoid damage to tubes and other internal components. Below are several instructions that MUST be followed when operating high powered tube type equipment. A. NEVER OPERATE THE AMPLIFIER WITHOUT A SPEAKER LOAD!! This amp is equipped with a shorting system on the main output jack to help protect against accidentally turning on the amp without a load. If the speaker patch cord is plugged into the amp, but not connected to the speakers, the amp is NOT loaded and could cause problems if the amp is turned on and operated in this manner. The-natural inductance of the output transformer can store energy that normally is transferred to the speaker and is capable of developing tremendous voltages. These voltages can cause serious internal arcing between the elements of the output tubes and their related circuitry. This is the MOST important consideration in the safe operation of your tube amp. B. The 6L6GC output tubes are the most rugged audio power tubes on the market and should provide long service in the output circuit. Each tube has a keying pin moulded into the base to index the pins into their proper positions. When installing or removing the tubes, it is possible to break off these index pins by bending the tube too much in its socket. Use extreme caution when handling the tubes. UNDER NO CIRCUMSTANCES SHOULD TUBES WITH BROKEN OR MISSING INDEX PINS BE INSERTED IN THE SOCKETS. If a tube is inserted in the improper manner (wrong indexing), the output stage will instantly be damaged when the unit is turned on. Use of tubes with broken or missing index pins voids the warranty. 17 The footswitch jack is of the "stereo" type and is used to plug in the footswitch for remote control of the reverb and tremolo effects. Any footswitch with the standard stereo phone plug and a shielded cable can be used. Footswitch is optional on the Classic i 41 it i. :t! < " t It ji !■ 1 { I i 1- № ill m : :t ¿X" T I 1. 1 PEAVEY ELECTRONICS TECHNICAL SPECIFICATIONS MODEL: CLASSIC POWER AMPLIFIER SECTION: A.
