TEAC A-4010GSL Rebuild Repair
Rebuilt this beautiful Teac A-4010GSL reel-to-reel tape machine with low hours. The GSL is the best model of the 4010 series.
I put in a new main drive and counter belt. Loosened up the seized capstan mechanism. Adjusted the brakes and aligned the reel platters. Demagnetized, cleaned the heads and checked azimuth/height. Checked play and record levels. Checked wow and flutter @ 3.15kHz for a measurement of .035% @ 7½ IPS, which is very low.
