luis,
Do you need a multi-channel HT receiver or is a 2-channel stereo receiver OK? If a 2-channel receiver is OK, something like the Nakamichi TA-4A would be awesome. However, with any vintage receiver they may need servicing or an overhaul to insure long-term reliability.
A better choice might be a more modern integrated amp from Arcam, NAD, Anthem, etc. More power, better sounding, but less features than a receiver (except for the very best receivers).
