Jack, Glad to here it isn't just my experience. Is your watchdog.co available? I've toyed with building a battery pack with 10 1/3 AA cells (2 banks of 5). This would give me 6v but the capacity would be less than just using 4 regular cells. I have two dead 8201's that both still have good power supplies so I may try it on one of those. I believe the resistor change would be on the power supply itself. It's nice to have a bone yard of parts to test with. Kurt
