Can I reduce the output of the pr449 like the pr266 by removing the 2 center tubes. That would give me a 60W amp instead of a 100W ?

However, I don't have an impedance switch to lower it like the pr266 have

Hi pilaf,

Yes, it would be closer to 50 watts with two tubes pulled. The impedance mismatch isn't anything to be concerned about, but if you want to match it, connect another 16 ohm speaker cab in series with the internal 16 ohm pair (difficult at best). You are probably wasting your time pulling tubes, you are not going to get a drastic reduction in volume anyway.

Thanks shimmilou,

I already tried and it works. Although you were right that the volume did not reduce for 50% I have gained a lot on the tone. Better than when I reduced the power at a 1/4 when it was full load 100W

Next thing I will try is to add a 16 ohm cabinet

Thanks again
