I have now finished a couple of CD player fixes, and am still looking for a Futterman H3 to bring back to life. If you have an old one sitting around, please let me know.
I am looking at it as a chassis, transformer, some tubes, maybe some tube sockets, and the circuit schematic (which I will have to extract from the existing wiring and components). The electrolytics and resistors are well past their lifetime, so a complete rebuild will be needed to bring it up to some level of performance and reliability.
If you step up fast, you may be able to get a Classe CDP-1 or Audio Note AN-CD2 in trade (both are already listed for sale).
