Choke loading question

I want to try some EXO-001 chokes in the Quickie. They are 1k ohm so the plate of the tubes would be at higher voltage than designed. Is that OK or should I do other changes to adjust the operating point?
Thanks a lot!

It's OK. The operating conditions are stabilized by the cathode resistor. You will draw a bit more current so the 9-v batteries will drain faster, but probably not enough to be noticeable.

xcortes,
I'm interested to know what you think of the chokes in the Quickie. I just received mine in the mail and having some upgrade options would be great.
