[BC] Te st Your Wits on This

[Richard_Rudman]

When I thought of changing the tube's orientation at KGB-FM in San Diego in 1973, it was getting close to 5 after a frustrating 4 hours of trying to neutralize a RCA BTF-20 E after installing a new final tube.

No matter what I tried, I could not get the neutralization procedure reading down to an acceptable value.

I tried a lot of things, including putting the old tube back in.

I have no absolutely idea why I tried reorienting the tube in the socket, but when I did, the RF neutralization value dropped to under 10 watts. 

By then making small adjustments in the tube's orientation, I got the value down to practically nothing, and got the rig on back the air shortly after 5 AM.
