Hello. I just finished a re-cap of my 2265 receiver. Recapped the power supply, power amp boards and the tone board. Also replaced the speaker protection relay and the filter caps. The receiver sounds excellent after the job. Punchier bass, better treble. Just more gooder all the way around. However, there now is a very slight "pop" when turning off the receiver. I don't hear it when turning power on. This problem did not exist before the re-capping. Any suggestions as to how to track down the issue? Thank-you.
