OK, updates...
I've purchased the deoxit cleaner and will set aside time to clean my tube pins. Haven't had time to do that yet. In addition, based on recommendations in this thread, I purchased the iFi Ground Defender and new heavy duty IEC cable (much better quality than my thin IEC cables that I had sitting around). I'd say the hum is decreased 90% when on high impedance mode on the WA22. Very good progress.
