help with Rotel power amp

got hold of a rotel power amp
the mains transformer has gone short circuit 2x 40v 0 40v
blown 5x 2SB817 2x 2SD1074 2x 2SB631K
what i would like to know is there an equivalent to the 2SB631K please see pic for the schematic
also the caps highlighted in schematic c609 & c606 should they be low esr or standard
c606 it only shows 1 on schematic but the pcb's are both populated with the caps
has anyone got a transformer or 2 that i could stack to replace the original UK ONLY
Regards Glenn

Are you 100% certain the mains transformer is toast? IME, Rotel's PTs are extremely reliable and rarely fail, especially the dual secondary toroidals.

Even if you had a single dead secondary, you could temporarily run both channels from the working secondary side, until you located a donor unit on ebay to scavenge the PT. The entire thing is SE common ground so it would be a piece of cake.
 
i have found a transformer with the right voltage but it only has 1 output 40-o-40 the original had 2 separate outputs
can i parallel the amp modules together as in connect both to the same transformer
or should i remove the rectifiers from the amp boards and just use one rectifier to feed the caps on both boards
