Re: Brenell Purchases
Series 2:-
Cleaned off all the black mess off the R/P head, its condition does not look great.
Cleaned the sticky mess off the 4 motor "Dubilier SFK24R" CR suppressor transorbs (0.02uF + 220 ohms), no sign that it leaked out of the suppressors.
Disconnected and measured them. All 4 measured 140 ohms ESR which I assume must be the 220 ohms resistor. Their capacitance was OK ranging from 0.02 to 0.033uF. Their insulation resistance was not great ranging from 750k to 3Mohm at 250 volts.
Measured the capstan motor Run capacitor C81 (2uF), a range of readings from 3 meters, 2.77uF up to 6.2uF. Poor insulation of 250kohm at 250 volts.
Will see how the motor runs, maybe time to replace the capacitor.
Cleaned off a nick/burr on the L2 Pressure Pad arm tape contact release pin.
