The 'last' Orion Bluebook of 2007 has them confusingly listed but to the best i can glean the three pieces of preamp, phono box and 'common' power supply should be (as per Orion) $1,700.
Curiously the prices from that book have been pretty stable. with the exception of the Phono box, which, with the increased interest in LPs in general, probably has doubled in value.
So "I" would start out asking $2,200. for the three pieces.
Andif you have the 'deluxe' power supply (in a similar size box to the phono and pre then $2,500.
If you only have the black mid-sized box like supply, then $2,200.
These are general guesses. And the market could be more, or less in the final analysis.
IF I were you i would sell the set on Audiogon. Posting pics of all three pieces, and ask $2,800. See what happens. If no offers, lower the price a few hundred each week. Even state that IN the ad. So folks who are interested but think the price is too high, will come back to look again.
When i sold an Audio Research Sp-10 I had five offers within twenty minutes. and that was at seven AM!! Clearly i priced it too low. But i did not cheat and pull the ad. I sold it at the price I listed.
So if it is priced low, the offers will pour in. If it is high, no offers.. If just right, a few offers in the first few days,
