Thanks, I'll test that out. I'm actually pretty sure it's perfectly fine, but it's hard to tell in the space in my basement. It might have just gotten to a point of indistinguishable difference in the alloted space it was in. I'm going to try using a multi-meter on the bias panel to make sure voltage does go up when switching to hi. That should be the determining factor.

If you're in a basement with that amp cranked to 10 at hi output, your head should have exploded unless you had your guitar turned completely down. Is it possible they've got incorrect replacement speakers in it? Again, try turning the amp off, setting it to low, then turning it on and check the volume level. Then turn the amp off, switch to hi, turn it back on and try again. Let us know what you find out.

Well, they're the original speakers, so it can't be that. I guess I'll try that once more and try the multi-meter tomorrow, which should essentially tell whether or not it's switching properly.

Well I tried it out once more, and have determined that there certainly is a difference, and I had someone say the same thing from the floor above me. The difference on the clean channel is not as big as the channel select, but I couldn't get close to turning up both gain and volume up all the way. That was going to get waaaaaay too loud. I also noticed a difference in tone when on channel select with hi and low, and from what I've read, low 25 watt is a better tone with distortion. I still have to play around with it. The difference in volume seems to come once you really crank it up.
I'm still going to do the multi-meter test, but now I'm almost positive that it's working fine and I'm just paranoid when it comes to buying anything.
My initial impressions are very good overall. I really love the clean tone I get on this.

Kids, take it from here: Switching the twin from 100 Watts to 25 Watts does not make it quieter. It just makes "clean" end sooner and results in earlier power amp saturation, but still at ear-piercing volumes.
If you wanna take it easy: Pull the two inner Power Tubes a n d adjust the Output Impedance!!!! The last part ist important. Impedance must be 1/2 what it was before. e.g. you were on 16 Ohms before, now it is 8.
What will you get? Your will get a 60 Watts / 12 Watts switchable amp. You will operate in Master Volumes around 4, even over 5 if you switch it to "Low".
The Red Knob Twin was designed to be loud, cause back then they needed louder amps on stage. You can tame it by pulling the inner tubes. Get good preamp tubes and the amp rocks. Mine has never let me down. Neither has the little bro, Super 60, which I also own. Sounds very different, to me than the twin.
Cheers
Ask for the red knob manual at the fender.com homepage, they will send it to you. It tells you about the tube pulling trick and other things,
