Sadly the Sencore was broke… but 4 4.6K resistors later BINGO…. a couple of the dummy loads have been REALLY heat stressed on the left channel so I have to find some more … sooner than later ( 100 watt ) 3.9ohm, 7.9 ohm and 2 16 ohm ( weird values ). if I tap HARD on em the R value changes ( opens up ) but I ran the 20K thru em at CLOSE to peak power for 5 minutes… and got the dummy load fan to kick on.. and both 8 him loads were nice N REALLY WARM….. I have a few non Hi Fi projects that I gotta get done.. but all N all MOST HAPPY...
