Melos MA-110b Tube Stereo Line PreamplfierI believe this is from the early 1990s, 1993-4 or so. I believe it is a hybrid design and uses two 6922 tubes. IT has two CD inputs (CD-L and CD-H) for different amounts of gain since at the time CD players had more variation. Also note the Phono input is just a line input marked as Phono -- you will need a phono stage. To be clear about this-- this is a line level preamp only. The input marked phono is for convenience, but this unit does not have a built in phono stage.NOTE: Selling As-Is -- works and sound decent but there is some intermittent light crackle. You may need to go over this and check for any issues. I think it was once looked at by a tech and had a couple components replaced, but I don't think it solved the issue. Was a long time ago and my memory is fuzzy. Still, could be a fun project.Includes original manual.Condition is decent with some scratches as shown.Any questions please let me know, and thanks for looking--
US$200 sits below the US$252 median and comfortably under the US$922 75th percentile, so on pure comps this reads as a good buy, especially for a tube preamp in as-is condition. It is not a steal relative to the very bottom of the market, but it is clearly on the affordable side for the current used spread.
The upside is the usual one for a well-liked tube line stage: a musical, full-bodied presentation with enough flexibility to be worth restoring if the circuit is sound. Because it is as-is, the key value question is whether the cosmetics are decent and whether the seller can confirm basic power-up behavior, noise level, and whether any obvious missing parts or tube issues are present. At US$200, a clean, complete unit still looks worth a serious look.
