4 ohm or 8 ohm tap on old tube amps?

I tried the different outlet taps on my tube amps with the speakers I was going to use and simply listened for the sound I liked best. It has worked out very well in a couple of different, amp/speaker combinations, without damage to amp or speaker. My advice use the tap that sounds the best

I agree with Mechans here...Using a 4 ohm tap won't hurt anything with 8 ohm speakers...I have usually found 8 ohm taps work best, even with 4 ohm speakers...but your milage will very much vary on this...just try it..

I find in general the higher the impedance tap used the better the sound. As Mechans says just try both taps, your opinion may differ.Trust what you hear.
