Sony 5.1 amp with PSB Speakers

Sony STR-DB930 receiver with 5 speakers and sub. Sony Amp STR-DB930 screen does not work. However I can get it to two channel operation with the buttons and appears to work just fine otherwise. PSB surrounds and center are fine. Main drivers are shot but tweeter works fine. Sub took some damage in a move turns on and works sporadically so driver probably good, amp might be salvageable. These are all free to anyone willing to pick up otherwise it will be thrown out in a week or two.
