Bias range resistor/400V tap?

Post by JDW3 » Sat Feb 11, 2012 12:32 pm

I just changed to the 400V tap on my 2203 build. But, I'm looking for 41mA and I can't get above 12mA.

I'm thinking I need to change the bias range resistor(47K)? Or, the bias feed resistor(27K)?

I tried the amp and it sounds good, but I don't want to run it this cold.

Try a 33k bias range resistor, that should get you in the ballpark.
