The Sansui 1000a is an integrated AM/FM receiver, that uses transistors in the phono section, and solid state rectifier. The Scott 299c is an integrated amplifier that is all tube, including the phono section, with tube rectification. The output transformers on the Sansui are said to be excellent, made by Hashimoto. Both at this point in time would need COMPLETE restorations, meaning every old capacitor including the cans replaced, resistors checked for drift, solder joints re-flowed, tube pin contacts inspected and cleaned, etc etc. I have seen some of the very incomplete messes done to some of these amps, so I would have a really good look at the work and description, and just who did the job. My choice would be for the Scott 299c, which I find easier to work on, less complicated without the tuner, and has a better phono section. I have had Scott 299c amps in the past, that worked with partial restoration, but just purchased one restored by NOS Valves some years ago, excellent work done.
