I got a pair of XSE10-4-8K op transformers from coop402. I only have 8 ohm speaker so I don't know if I can even use them. If I hook 8 ohm speakers into the 4 ohm secondary the primary sees 16K, is that right?

I tried 1 volt RMS into the secondary from another amp's output and got 46 volts out of the primary. Since this one has a screen tap I tried different connections to see what I would get. Between the plate and screen I got 25 volts out with 1 volt in or 25:1. Could I use this as a 5K to 8 ohm now?
