It tests ok. I ordered a few 4r7 and the 33uf 16v caps. I didn't have any. The 4r7 in front of the driver card looked a little burnt, so I replaced it with a 5r1 I had from a Rockford. Same result. D611-d612 are reverse polarity diodes? When powered up a sizzling sound emmits from power supply transformer, or those diodes.
