All input/output jacks cleaned and lubricated. New pots and control knobs fitted around 15 years ago. All voltages checked. Fully tested and sound checked.

Full spec in more detail:

All (with the exception of one) original Gold Military Specification integrated circuits fitted, stamped 7110 (dated 10th week of 1971)All the pots and control knobs were replaced around 15 years ago for very high quality, smooth items. The soldering work was carried out to a very high standard. I tried fitting a set of original HH knobs but the new pot shafts are too small so I left the knobs that came with the amp in place
Amp serial number 5576DNew mains switch fitted
Original Bulgin power inlet socket fitted, and includes a period Bulgin power lead fitted with a UK 13 amp mains plug. I can fit a new IEC type, and supply a new IEC mains lead fitted with a UK 13 amp plug if preferred.
Sounds very good, and very loud.Everything works as it should.

Should be good for another forty-five years reliable service.
I will need a contact telephone number from you for when I book the courier. Price quoted is for fully insured and tracked UK mainland delivery, highlands and islands will be more expensive. Check with me first with your postcode for a firm quote.

Overseas buyers will receive the amplifier through the eBay Global Shipping Program which is fully tracked and insured.
