Thomas Mayer 46 SE tube AMP? What's it worth

Start an auction and find out what they are worth, or you could subscribe to bluebook or check Ebay completed listings.

Subscribe to the Audiogon blue book service. Most, if not all, of these items will be included.

You can also use http://www.hifishark.com/ to see which of these items may currently be for sale as well as any completed listings. It checks most of the popular sights for audio equipment sales around the world of course including Audiogon.

Thanks for the advice so far.
I am still negotiating to buy the equipment, but want to be sure that I'm going to profit and also want to be sure that my offer is competitive and fair to the seller.

Thanks

Steve

I assume that this is UK based system (seems very familiar), which will affect the prices of the individual components.

If you are planning on using the system then research each component for UK sales data (the system is for a small room and/or listening in the near-field).

If you are planning on flipping it for a profit then I doubt you will be successful (based upon the nature of the gear itself and the nature of your query).

If I'm right (about the provenance of the system) the Thorens is a refurbished TD124 oil bearing and the Harbeths are the little P3ESR's.
