That's an expensive Regulator isn't it ???
I battled a lightning struck JVC(AV32120),that is until
I ordered an OEM STR-F6626/F7 from JVC.
Here's a list of parts from that repair
IC901 STR-F6626/F7
R914 2.2ohm
Q911 2SA1037ak
Q921 2sc2412k
Q922 2SD1383k
Q942 2SC2412K
Q944,Q927,Q928 DTC124eka
PC901,PC902
