RG50TC Biasing

[osu122975]

Anyone know how to bias this amp?

There seems to be a small three prong connector on the back of it that might be used to do the biasing.

Does Randall offer some sort of connector or biasing tool to do this?

Thanks for any help.

I doble tha tquestion and would also like to know the recommended values for biasing.

Thanks in advance for a reply.
