Hammond 1628SEA - Wiring question

[txtone]

I am connecting everything in preparation to bench test my SSE. My question is about the blue/yellow wire on the 1628SEA OPT. According to the Hammond cut sheet this wire is the "40% Screen Tap". Is this wire the same as the turquois/bright blue wire in the tubelab website diagrams? (see attached) Does connecting this 'screen tap' configure the amp for Ultra Linear?

Yes, and Yes. Leave this wire unconnected for triode mode. Tape up or otherwise prevent the wire from touching anything since it will have a lot of voltage on it.

Thank you sir!
