It had a 'W' as it had white knobs and was one of 'The Shadow's' amps and made in early 1960. AC30 Serial numbers started with the number #4000 and JMI made around 20,000 AC-30's.
That was the only Serial Number that was recognized by the factory.
All JMI/Vox Amps had a Serial Number on the plate that was affixed to the back panel of the cabinet. This Is Not the actual Serial number, but an inventory control #. There should be a 'Ser.#' on the chassis under the power switch. Vox/JMI made these models: Bass, Normal, Treble, Top Boost and all model w/o Top Boost could be retro-fitted with a Top Boost on the back panel. But JMI/Vox never made an AC-50 combo.Īnyway, until I can see some photos I can't give you any clue as to when it was made, however since it's a non-Top Boost, it will have to have been made before late 1965. There are date codes on some parts, mainly the Wima Tropyfol caps(gold coloured) and also on the 'mustard' caps, woden Tranny's & Hunts filter Caps. The originals should have Blue alnico Celestions up until April 1964 when the colour changed to 'poly gray'. Hi! I work on original AC-30's all the time.
