So while tackling a speaker mod today, I decided to check the DC offset of my Adcom 5400. I set my meter to 200m on DC Voltage and got some weird readings. (Disclaimer - My meter just wouldn't sit at a stable reading of 0 when trying to conduct this. Cheap POS)
After 10 minutes of idling with nothing hooked up:
Left Channel: 68.7
Right Channel: -0.0
Wtf?? SO I powered it down, re-checked my settings, powered up and checked again after 30 seconds or so...
Left Channel: 78 (Was slowly dropping. Stopped reading at 72ma)
Right Channel: -2.2
Something is not right. The left channel is a bit over that magical 50 number but its the right channel that scares me. Is that normal?
Regardless, I have always thought the left channel sounded louder/fuller if I can use that term than the right channel. I have been meaning to take this into my amp guy here for a check over. I will probably do this quite soon as I don't want either amp or speakers to go POP! I should note that I removed the jumper between the negative terminals before taking these readings.
