This particular A810 has had extensive recent service, with updated microprocessor chips on the MP Unit, conversion from the (ever failing) VU meter incandescent lamps to LEDs, replacement of all non-tantalum electrolytic capacitors on all card cage plug-in PC boards plus (even more important for stability and freedom from breakdown) replacement of all backplane electrolytics. Further, the memory backup battery has recently been replaced and lubrication of the capstan motor (fore and aft) using the factory mandated lubricant has been done. As a result, Wow & Flutter is now outstanding: 0.03 @ 30 ips, 0.035 @ 15 ips, 0.05 @7 ½ ips, and 0.07 @ 3 ¾ ips.
And yes, this is a 4 speed version, meeting virtually all recording and playback needs. Finally, the heads have been professionally re-lapped by the best experts in the field: JRF Magnetic Sciences. So, not only are the technical specs met, but also dropouts are absolutely minimized. The photos show the cosmetic appearance, with only minor nicks and scratches here and there. This 2-channel A810 is being sold just as you see it in the pictures
