NOTES
l. Thesetrays contain 6.0683Ampffier Cards.
Field modification kits areavaihble(2.1450;
one pel tray) that add over-voltagelimiters
to the 6.0683 Ampffiers; the modified
amplifiers are designated 6.0831, and the
modified tays are then designatedwith the
New Seriesnumber.
2. These trays are identical with their equivalents in the Old Series column except that
6.0831 or 6.0842 Amplifier Cardsare suy
plied (the 6.0842 Ampffier Card has the
over-voltagelimiter built on the ftwin circuit
board; the 6.0831 is electrically identical,
but the over-voltagelimiter is on a small
outboard circait card)- The 70.00251 and
77.0023 trays have no OId Seriesequivalents.
3. These trays should not be used in a computer wpplied with a 63.0223Master Control Tray.
4. These trays should be located in positions
controlled by 77.0026Combol Track-Store
