Documents - the Vox AC30/4 and Vox AC30/6
later 1960 and 1961
Below, a selection of documents relevant to the AC30 in the second half of 1960 and 1961 - some part of a large batch sent by JMI in 1961 to an enquirer who lived in Hull.
The principal change outlined is the move to the new six-input AC30 - the AC30/6. An AC30/4 bought before 1st October 1961 could be had at the old price of 95 guineas (£99 5s). A new AC30/6 Twin would, as a special introduction, be 100 guineas (£105). The price thereafter: 105 guineas (£105 5s).
In 1962 the price of the AC30N went up to 115 guineas (£105 15s); the AC30B was 120 gns (£106).
The page on documents from 1962 is now here.
