Should I pull the tubes?

I have a NYAL Minuet preamp in transit to me. It uses 4 12AX7 tubes. Two in the phono, two in the line stage.

I don't plan on using the phono stage. Could I pull the phono tubes and leave the tube sockets empty, or will doing that affect the performance of the preamp?

How many times are you going to ask this question ?

As one member suggested, why not just buy some cheap tubes and place those in the phono stage section of the preamp and keep the other ones for spares.

For under $20 your problem would be solved.

My error. I did not realize that someone responded to the question. I was unsure if I had the right password. A little patience, perhaps?

Thanks, Newbie. I'll just put cheap ones in the phono section. I was wondering if it could affect the line stage, maybe even send the unit into oscillation. I had an early Audible Illusions preamp that oscillated when I unknowingly put in some Hungarian tubes. They even warned about this in their manual. I was just curious if the circuit could be affected in some way, as Hifigeek1 suggested.
