4 ohm tap vs 8 ohm tap

Hi Al. I would suggest listening to Al. He and I discussed this very same topic quiet some time ago. My speakers, Roman Audio Centurions are an 8-ohm rated speaker and I am running them on the 4 ohm taps on my tube amp. At first I didn't think there there would be a difference, but Al was right, there is. Try it and see for youself.

SHAMELESS PLUG: Al does make a really awesome tube amp, I use one.

Thanks for the corrections Al. I did a quick internet search and you are right on the money. Thanks again. Gotta watch who you get advise from!

Thanks, I just wanted to make sure there were no issues before I started running them like that for an extended period of time. I tried the 4ohm tap and I felt I liked it beeter that way.
Thanks again. Scott

Aroc,

Alraul is correct - the full primary winding is always seen
by the output tubes.

The different taps are on the secondary side of the the
transformer with higher tap impedance having more windings.

Hence the 4 ohm tap will have the fewest windings of the
set of 4, 8, and 16 ohm taps.

Well, I can definatly notice a difference. I just got these speakers about a week and a half ago. When I first hooked them up I forgot to change from 4 to 6 ohm because my Thiels are 4 ohm. I liked the speakers right away.
After I noticed that I forgot to change to the 8 ohm tap, I quickly changed the amps to the 8 ohm tap.
After a few LP's I began to not hear the bass. So after you all confirmed that I would not damage anything, I switched back to the 4 ohm tao. The bass is back.
You need all the help you can get with the Shearwaters. They are not bass heavey at all.
Thanks, Scott
