Please keep in mind that those components must be original to get a valid date for a vintage guitar amplifier.Other sources to date your amp may include serial numbers and overall look and visual components on the amp as well.For over 50 years, Marshall has been a household name throughout the world, as a symbol of precision acoustic engineering.Not only for its unique, legendary tone, but also for high performance night after night.Again, it's important to be sure the parts are original on the music equipment to get a valid date for the amp.Many tube amplifiers will have a tube chart within the amp itself.In this article, I’ll try to cover the more “desirable” Marshall amps that were built since 1962 up to the JCM800 series, wich most consider to be the “last” great Marshalls produced (That until Marshall released the Vintage Modern series.

You can end up buying something that is not what you expected or even something that is damaged or modded beyond repair.
So, always keep your eyes open for “fishy” deals, look for information, and always ask for high definition photos (especially from the interior of the amps – the circuit, the tubes and transformers) to make sure everything is right.
For example, the logo on the amp or materials used during a certain time period of production.
Dating an amplifier by serial numbers can be effective as well.
