Type 69 Passive Equaliser

The original Type 69 was produced in a number of different versions — the early ones being developed while Dick was at Olympic Studios and the later versions for Island and others. The principal differences related to the transformer type and whether germanium or silicon transistors were used. Since Helios was a custom console manufacturer, these differences were quite normal.

The reissue will feature:

The Lustraphone clone

The materials from an original Lustraphone transformer were analysed at the UK's National Physical Laboratory so that this clone would be as accurate as possible.
