SB 301 & 401 VOX feed back

I'm experiencing a feedback from the microphone with the above pair that
is causing the 401 to go into transmit. I've checked the anti-vox
connection and have increased the anti-vox adjustment to max but still
have the problem. I've pulled V13 (I think) and checked to see if I had
an input from the anti-vox jack and observed the varying dc voltage on
the tubes grid socket from the anti-vox. 

 

Any suggestions? 

 

Thanks
