Internal shot of the ex-ABC CEI preamp.  Note the amount of point-to-point wiring!
Ex. Australian Broadcasting Commission Preamps

These two brown units were rescued from the A.B.C.
Radio National.

They were originally designed as mono preamps to
matching 1/4" mono tape drive units.
The units are basically a solidstate version of the
Beyer / Rola 66 (badged as a 77 Mk.IV).

Currently i'm building power supplies to get these units
up and running again.

They certainly look promising. They feature massive
transformers on every input and output.
They have a mic input, line input and front DI (bridged
high-impedence, transformer balanced) and i just can't wait
see how they sound.
