Hello,
I just looked at the k4307 manual. I see you can use a 10 ohm resistor for the low power rating and a 1k for the high power rating. I am considering this for a ver low power tube amp. Can I sub the 10 ohm 1/4 watt for a 1 ohm(maybe 1/2-1 watt) resistor and get an even lower power rating - somethin like .015 - 20 watt metering?
Thanks!
If the voltage at the input is less than 1.7V, the leds will not light.
This corresponds with -/+ 0.36W in 8 ohm.
I’m looking to do something similar. Is there any substitute value for R13 that would give a range of about 100W at 8ohms?
Sorry, no values. Please experiment.
I will do 
Thanks.
