From the Chairman Congratulations on your purchase of the limited edition reissue of the offset JTM45 halfstack. The original versions of this amp and cabinet were built back in 1962, the very year in which Marshall Amplification was born. In fact, the offset head was the first version of the JTM45 my company made and only a mere handful of these heads and cabinets were ever constructed.
WARNING! Please read the following list carefully. A. ALWAYS use the correct power cord B. NEVER attempt to by-pass the fuses or fit ones of the incorrect value. C. NEVER attempt to replace fuses or valves with the amplifier connected to the mains. D. DO NOT attempt to remove the amplifier chassis, there are no user serviceable parts. E. ALWAYS have this equipment serviced or repaired by competent qualified personnel. F. NEVER use an amplifier in damp or wet conditions. G.
JTM45 O/S Front and Rear Panel Features (continued) Front Panel Functions 1. Power Switch On / Off Switch for mains power to the amplifier. 2. Standby Switch Controls H.T. or high voltage to the valves to allow them to attain correct working temperature before playing. To prolong the life of the valves it is always advisable to switch on the Mains Power Switch (item 1) about 2 minutes before switching on the Standby (item 2). On switching off, the Standby should always be switched before the Power Switch.
