The phone jacks break the cathode circuit of each final so you need to set your meter to measure current not voltage. A typical W4 will draw somewhere betw 40 and 70 mA/final so a meter setting of ~ 100mA FS is appropriate. Go back and forth betw the 2 jacks while slowly adj the bias balance pot till current is equal on both. There is no absolute bias value adj, just balance.
