Very good condition original JMI AC15 Twin amps are very rare indeed! I hate to part with this one! I purchased this about 15 years ago from Ampaholics , a reputable UK based dealer of vintage British amps. The serial information I used to date the amp is from the benchmark book VOX Amplifiers: The JMI Years published in 2012 by Jim Elyea. I think it is accurate but no guaranty. It could be a year or so either way. Here is what I can say:-amp works great and has an exceptional VOX tone.... Remember, the Beatles started out with AC15s!- This has the original power cord with a British plug but will include the adapter to convert it to US plug. The amp has the stock voltage selector switch so you can plug straight in with no transformer needed.- Check out the original 12 inch speakers with serial numbers 35777 and 35781 - 4 speakers apart !! - original footswitch is included and tremolo works fine- the back panel plate with serial number is the Type 7 plate which first appeared in 1964- tolex and grill cloth appear original. Minor wear that is very minimal for a VOX amp of this vintage. See pics. - one or more handles and misc screws may be replaced. I cannot tell for sure. Either way the handles are original VOX parts and are vintage themselves. - I believe this is a 1966 amp by the back panel serial number of 01366 and by other amp features using the Elyea reference book. Possibly it is a 1965. - this amp still has the original “Fifteen Twin” badge on the front bottom right grill cloth. - amp has the original Fane 12” speakers. Cones are in good shape but I have no idea if they are original. These speakers sound exceptional. - gray control panel- comes with a vintage VOX amp cover -has many old Mullard BVA tubes. You can see the EF86 Mullard pre amp tube in pics. - original transformers and choke. -plenty of the sought after WIMA components on the circuit board. What else can I say? Feel free to email me with any questions. I can also send serious buyers more photos. This amp shipped to me right from the UK so I am comfortable shipping it well packed in the continental US. No international shipment. Sorry. Winner must pay within 3 days of auction end or the bid and sale may be cancelled.
