1964 Vox AC50 MK1 Small Box

This particular version of the AC50 was only made for a few months – the crossover between the classic Diamond Input, Copper Panel, to the big box 2 channel AC50. The cap codes, serial number and modelling all date this to mid 1964.

Although we cannot prove this, the previous owner stated he purchased this from a charity who had been donated a tonne of Brian Jones’ Vox amplifiers back in the late 60s. As stated, we cannot prove this. We’ve tried to find as much information as possible to support this supposed owner but have had no luck. It would be extremely cool if it was the truth!

Serial Number: 1506

Valve Brands: 3x Mullard, 2x Electro Harmonix & 1x Unbranded & 1x Sovtek

Transformers: 2x Original (one looks to have been rewound in the past) 1x Replacement (choke)

This amplifier has been serviced to a playable & safe standard, by one of our leading amp techs. To find out more about what our service includes, please check out our terms and conditions before purchasing.


Overall ‘excellent’ condition. There have been two extra jack sockets drilled to the back of the amplifier, and the original hole has been left open, as you can see. The original power cable has been changed for a newer IEC. The voltage selector has also been removed, meaning this is currently wired for UK voltage.

Please have a close look at the high resolution photographs below, as these form part of our description.


Internally and externally original, including transformers, except for minor service component changes i.e. caps, resistors, etc, the replaced choke, and the rewind on the D8869 transformer.

At The Music Locker we will do all we can for you to get the instrument you want. You’re more than welcome to come and have a play on this, coupled with one of our vintage guitars!

The Music Locker prides itself on offering vintage and collectable pre-owned instruments and equipment (the Products).

We take all reasonable steps to ensure the equipment has been inspected by a competent person in the UK to ensure it complies with UK safety standards. This may mean it does not comply with the current standards in the country in which it will be subsequently used. It is the purchasers’ responsibility to ensure it is inspected by a competent person knowledgeable with the relevant electrical safety standards within that country, prior to connecting to any live electrical circuit.

It is the philosophy of The Music Locker to keep all items as original as possible, only changing original components when absolutely necessary. This includes valves, capacitors, transformers, potentiometers, frets, etc. This gives the buyer the option of tailoring to their exact needs, and may mean that the item is not operating at optimum performance levels. Therefore, your personal preference may differ, depending on your circumstances (i.e. collector or musician), and you may decide to service the item in more depth upon receiving.

The Music Locker cannot accept responsibility for any costs of refurbishment to a standard different to the one advertised.
