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.

We are finalising the production of a Type 69 Equaliser re-issue as a series 500 module featuring a Lustraphone-clone transformer. It should be available in Q3 2018. We don't have pricing details yet, but if you have more than a passing interest please contact us.

Prototype Type 69 Equaliser

Type 78 Active Equaliser

This was based on the last consoles delivered in 1978/79, offering active equalisation with all parameters continuously variable.

We have a rack-mount prototype version, but we're thinking that a series 500 dual-width module might be a better start. If you are interested or have comments then do get in touch.
