Greg did a fantastic job on my 70 AM 8 track about 15 yrs ago & since he's no longer doing tape players, I just got my am fm 8 track back feom Barry's and what was "beyond repair" by other guys came back better than ever. I did get his Aurora internals mod. But be willing to wait or pony up an extra $149 for a 2 week turn around, which I consider is well worth it. Even sends you a dvd of your unit's final testing.
