I agree you can find some G02 around/below the 1k mark.

But I would first try to get a 502, as they are identical on the inside (same toroidal and electronics, but the front panel). These go for lower sums (and maybe you have other 5xx components to match better?).

Basement: Linn Sneaky DS, 568.2mm, ARS Sonum Gran Filarmonia, Ramallo Allegro.
Living Room: 602, Linn Akurate DSM, Hypex Nc400, B&W 802D.
