go through the checks he gave.
AC V@ plug before L46/L47 and after.
AC V@ primary of power xformer (blk-red/black)
AC V@ secondary of power xformer (red/red-green) before & after M7, 143ac
DC V& Ma@ L54 395V 580ma.

145v is sourced via 5.6k resistor (r216) from the 275v rail, and goes to L25 & v9, as mentioned, if things are not right in other parts on the set, the load on the 2 won't be normal, and it will drift up.
