Vintage 1974 Marshall JMP Super PA 50w Amplifier Head
Vintage 1974 Marshall JMP Super PA 50w Amplifier Head
This wonderful 1974 Super PA was found in an attic a few weeks back, where it had been gathering dust for some time. The dust kept this in incredible (and I mean incredible) condition. This is a rarer 50w model, model code 1963, not often found like it’s bigger brother the 100w. Cosmetically it is in incredible condition, with literally no scuffs or scrapes on the outside. The previous owner changed the knobs to a later 1970s style knob, otherwise totally original. Internally, it is in wonderful condition.
These 50w chassis’ were all drilled for the 4 large caps, but they were never used from the factory and have a metal plate covering them instead. The transformers are all original to the amplifier (1202-164 mains TF, 784-139 output TF and the choke), and work perfectly. It has a nice pair of Siemens EL34s inside, fully tested, and a mixed quad of ECC83s. The circuitboard is relatively untouched, and has recently been checked over by my leading amp tech. It’s a true beauty, a real stunning example. You will not be disappointed – grab a bargain!

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.
