Reel to Reel Tape Machines / Re: Studer A810 stuck in "Safe"
« on: August 23, 2013, 03:51:18 PM »
OK, I've answered my own query! The Basis board foil that feeds 5.6V to pin 24 on both record boards had opened while on the shelf-this pin sends a signal back through a 1K ohm resistor via pin20 on each record amp board that lets system know it is in place-no record board, no "Ready"! I had replaced C10 on gthe basis board-the foil in question had opened while sitting on the shelf-apparently my removal of the old C10 had weakened the foil just enough to cause it to open later.

Reel to Reel Tape Machines / Studer A810 stuck in "Safe"
« on: August 15, 2013, 04:50:43 PM »
I have recently brought an A810 back from the dead-many Frako caps and a backup battery later and it was working great. I left it on the shelf for several days while waiting on new meter lamps. I put the lamps in and it will not come out of "Safe" mode no matter what. Checked all the dipswitches and jumpers, checked for pinched wires-nothing. Does any body know what's wrong?
