A detail from the JMI amplifier brochure of late 1957. An early pre-production version of the AC1/15 is illustrated and priced in this brochure. On the initial design, see this page.

1958 to 1961

Below, an overview of prices for the AC15 in the period 1958 to 1961, a digest of around two dozen contemporary sources (for some months no source, for others multiple).

Late 1957 / early 1958 - AC.1.15

Initial design: 42 guineas = £44 and 2 shillings.

March to September 1958 - AC1/15

March, May, July and September: 57 guineas = £59 and 17 shillings.

March 1958.

October 1958 to early 1960 - AC1/15 (from July '59 generally termed the A.C.15)

through to April 1960: 59 guineas = £61 and 19 shillings.

May 1960 to February 1961 - AC15 Normal and Bass

AC15 Normal: 65 guineas = £68 and 5 shillings.

AC15 Bass: 70 guineas = £73 and 10 shillings.

May 1960.

March to December 1961 - AC15 Normal and Bass

AC15 Normal: 70 guineas = £73 and 10 shillings.

AC15 Bass: 75 guineas = £78 and 15 shillings.

4th March 1961.

It is likely that the new prices introduced in May 1960 correspond with the move to the third circuit AC15, and that those of March 1961 stemmed from the introduction of split-front cabinets.

1962 to late 1965.

For the whole of 1962:

AC15 single speaker, Normal: 70 guineas = £73 10 shillings.

AC15 single speaker, Bass: 75 guineas = £78 15 shillings.

AC15 Twin: 85 guineas = £89 5 shillings.

For the whole of 1963 and into late 1965:

AC15 single speaker, Normal: 80 guineas = £84.

AC15 Twin, Normal: 95 guineas = £99 15 shillings.

AC15 Twin, Bass: 100 guineas = £105.

Note that in 1962 no AC15 Twin Bass is listed, and that in 1963 no single speaker AC15 Bass is encompassed. However, the latter was occasionally noted as being available for an extra 5 guineas (in other words 85 guineas = £89 15 shillings).
