Replacement Valves. About the Marshall JCM800 2203 amp:

This JCM800 re-issue, 2203 model (’81-’84), is one of the most highly respected 100 Watt Marshall® heads. Originally evolving from the ‘Plexi’ head, the JCM800 was one of our first amplifiers to feature a Master Volume control.

The JCM800 2203 remains the essence of simplicity; it has one channel with no Reverb. Its purist-pleasing front panel and distinctive roar set the standard by which all other rock amps were judged. And it is still produced because of continued artist use, and of course by popular demand. The only modern addition made to the JCM800 2203 is a tonally transparent Series FX Loop.

The Marshall JCM800 2203X Vintage Series 100W Tube Head is the original amp behind Eddie’s famous “brown sound” from the 1981 to 1990 era. It’s still backing some of rock’s greatest including Zakk Wylde and Kerry King. Three ECC83s and four EL34s pumps out 100W of that inimitable Marshall overdrive. If you are an effects freak, then this is probably not the amp for you.
