Finally got around to joining AK. Been buying/selling/playing with vintage audio for a while now. On Saturday I picked up a (The) Fisher Statesman receiver. The nameplate identifies it as Model CO-6R. I've never heard of it, and I can't find any reference to it anywhere. I didn't see it on your list. It looks exactly like the 250/400 Tune-O-Matics. Has a wood cabinet that I think was an option. Has anyone heard of this model? Right now I've got it torn apart but here's a pic of the nameplate.
Welcome to AK. Congratulations, I've never heard of the CO-6R either! Fisher used the 'CO-' designation on their "Consort Component" systems beginning with the CO-1 and CO-2 in late 1971 for the '72 model year. This was a complete component system (receiver/TT/speakers) sold as a unit under the CO designation. I had no idea the chassis were marked with that designation, though.
The CO-1 & CO-2 were built around Fisher's
Futura series 201 & 202 receivers, respectively. Then, sometime around mid-season 1972, Fisher expanded the Consort line with a two-tiered lineup consisting of a lower
Custom Consort Component System - CO-11, CO-12 (170 receiver), CO-13 (180 receiver) - and a higher
Deluxe Consort Component System - CO-14 (180 receiver), CO-15 (203 receiver), CO-16 (205 receiver). The CO-14, -15 and -16 carried over into the 1973 model year. By 1974 Fisher had dropped the Consort concept and was beginning to focus on its Studio Standard components. The Consort concept was a comparatively short-lived experiment from some of Fisher darkest years.
You will note the receivers utilized in the Consort lines were Fisher's entry-level models of that time. Prices for the systems ranged from $250 to $500 which was fairly reasonable for a complete Fisher system though certainly not cheap. If, indeed, your receiver is a 250-TX/400-T with a Consort designation, (as I think likely,) it would have been about a one year older design than the rest of the three-digit receivers noted above. That might explain why it was being offered as part of a budget-priced system: it was leftover stock Fisher (Emerson) was trying to move. However, I cannot account for the
Statesman designation unless it was originally slated for such an installation. That particular console chassis should be designated the 25-R. Furthermore, I can find no reference to the CO-6R in any of the sales literature or price lists from that period. The 'R' suffix is interesting since it seems to relate back to the chassis designations which were applied to Fisher's component receivers when used in a console. However, the wood case argues against it having been used in that application. It is a very unusual and perplexing model you have there.
