That looks about right, ive (I've) the basic spec written down here side by side for them both, yes the EM84 says -22v, the EM87 -15v

Ive (I've) also checked the potentiometer size iI was looking at, and it says 5M. That sounds better with the grid resistor value on the spec sheets than does my original guess of 10k!
