The History of the JTM 45 Layout
The JTM 45 layout was first introduced by Marshall Amplification in 1962, and it quickly gained popularity among musicians.

The JTM 45 layout consists of several key components that work together to create its signature sound. The power section of the amplifier includes two EL34 tubes that are connected to a rectifier tube and a power transformer. The preamp section consists of three ECC83 tubes that are connected to various resistors and capacitors, which shape the tone of the amplifier. The JTM 45 also features a GZ34 rectifier tube, a feature that has been preserved in many modern versions of the Marshall amplifier.
