Vintage McIntosh, Tandberg, etc. Equipment I want to Sell

[thatoldaner]

My husband passed away 6 years ago and I have several pieces of his vintage stereo equipment I would like to sell (McIntosh, ADS, Tandberg and dbx). I did a little (very little) research a few years ago trying to determine the value of this equipment. Some pieces I located; some I did not. Some of the equpment is in good condition; some of it in poor condition. My early research showed that even in poor condition, some of the equipment I have is quite valuable. It appears the most valuable piece I have is a McIntosh MC2500 Stereo Power Amplifier.

I really need to get rid of this stuff, so I am resuming my research in an attempt to determine a selling price and the best place to advertise it for sale. Can anyone recommend some web sites where I might find the value of this equpment and also some web sites where I can place it for sale. I have the following equpment:

McIntosh MC2500 Stereo Power Amplified
McIntosh XR6 Speakers Isoplanar Radiator System
McIntosh C32 Stereo Preamp
McIntosh MX113 Stereo AM/FM Tuner Preamp
ADS Model 10 Acoustic Dimension Synthesizer
Tandberg TCO 440A Cassette Deck
dx 3BX 3 Band Dynamic Range Expander

Thanks you for your help.
