Default Re: Sugden preamp WAL AC Farnell.

Thanks everyone, such a torrent of illumination.
Initial response on the unit from the manufacturer:
- The unit hasn't been seen before.
- The circuit boards are not from another Sugden product.
- It was built for a special purpose, possibly part of a test rig.
- The circuit boards are estimated at 1967-8.
Curiouser and curiouser.
