6922 Heater - BIAS

[mickie]

Hi all,

i have implemented a voltage-divider in my WCF - Headphone - Amplifier (6922-Tubes) to bias the heaters at about 40V; connected to the center-tap of my Hammond 369EX (3,15 - 0 - 3,15V AC)

Could i (in addition to that) also put a small cap from the heater-pins to ground in order to reduce noise or would that interfere with the circuit/heater bias?

As a newbee, i'd appreciate any comments!

regards,

If you have an oscilloscope to put on the heater pins to compare before and after, you'll be able to see why...
