Default Re: Important info for Revox B215 alignment

A few more findings on REVOX B215 and Studer A721 decks.

1-The capacitor C10 seen on the pcb of the System Control Board on both decks is connected
between the resistors R35 and R36 and ground.
While it exists in the System Control Board schematic of B215 it is missing in the A721's.

2-The capacitors C27 and C28 in the +5VDC psu on both decks have been replaced in later models
by 10uF/35V tantalum capacitors.
