Vox amp serial number dating
The Vox AC30 is a guitar amplifier manufactured by Vox.It was introduced in 1958 to meet the growing demand for louder amplifiers. Vox serial numbers weren't planned out too well, nor is there a lot of information on the rhyme or reason for the numbering that occurred in Britain or in the Italian factory.It was in late 1964 that the Italian factory began making Vox guitars, while British production of Vox guitars continued simultaneously.
This second generation AC30/4 had two channels with two inputs, hence the "4" in the model name, and a single tone control, and was powered by a quartet of EL84 (6BQ5) power tubes, making it truly a doubling of the AC15 power amp circuit.
There may be "patterns" here and there, but nothing that one can rely on. The chassis, as mentioned, were then taken to Dartford, where the back panels were attached (the connectors soldered to the terminals in the amp), and the chassis screwed into the boxes that had been assigned. One can often get a good general sense of date from the type of box, whether or not the amp has a valve rectifier, and last but not least, from the two-letter date codes on the potentiometers: Serial number 1727.
Some of the pots are replacements, but the one indicated is original and bears the code "GL". The first letter is the month: "A" = January, and so on.
The range reflects our tastes so you'll see an unusual mix of classic British and American amps from Vox, Marshall, Fender and Gibson alongside less-common fare from Selmer, Watkins/WEM, Ampeg, Supro etc.
Our amp tech has been working on these units since the 70s; we pride ourselves on selling vintage valve amps that will perform as close as possible to when they originally left the factory, though sometimes they can be 'improved' beyond original spec.
