like what's in the Mac Mc240 and the Citation 2.Now I had a 50 ohm choke in there at 1hy.I took it out and put in a .5hy at 30 ohms..The B+ went up 2.3 volts.having a choke there really improves backgrounds,clarity,and overall control of the amplifier.I'm going to use the HF89 bias scheme and the reason I like the older bias schemes where they use a balance and bias pot,it is so much easier to bias because you aren't chasing the bias so much.
