|This price list offers no date but the product offerings listed offer excellent clues to when it was released.
The AC-4 was introduced in late 1961, about the same time that AC-6 production ended. The AC-30 Super Twin and the AC-10 Twin amps both made their earliest appearances in the first half of 1962. The T.60 bass amp, introduced in the fall of 1962, was not mentioned in this price sheet.
This suggests that this price list was probably from the first half of 1962.
