Re: Altecs & tube amps......
Over on diyAudio I posted a test that will allow you to figure out how much power you actually need. It's pretty simple if you have a volt meter with a 20V AC scale.
FWIW, I use about 1/8th watt average when playing loud. At the very loudest volumes I ever use I got 4.5W peak. That's it. YMMV
I can post the test here along with instructions, if anyone is interested. It's easy to do.

PLEASE post that Pano!! I would be very interested in seeing that.
If there is one thing I ever had a hard time explaining to people, its how few watts they actually need with their VOTT's.
Re: Altecs & tube amps......
One more thing Pano...
I just checked all my VOMS including a Simpson 260 and none have a 20v scale.
The 260 has:
2.5
10
50
500
I dont recall ever seeing one with a 20v scale.
Re: Altecs & tube amps......
Note to Russ:
You can see how many watts you are using.
Your G-9000 has power meters. Says WATTS (8Ω) PEAK
You want to read the top scale. It starts at 0 and then .1 (one tenth of a watt), then 1 watt, then 10 watts and goes on.
Anything over 3 watts with those 19's should be ABUSIVE. :biggrin2:
Re: Altecs & tube amps......
OK Nipper, I'll start a thread with the test and the test tone.
Your 10V AC scale will be fine. Most modern DVMs do a 20V AC scale. It's just that the cheaper ones usually don't have a low voltage scale for AC. As the voltage will be low, the low scale is needed for accuracy.

"Most modern DVM's"....?!?! Was that a dig? I LIKE MY 260!!!
Then I was thinking "DVM"???.... Hmmmmmmmmm. Doctor of Veterinary Medicine? Nah.
I had to look that up.
In my days we called em VOM's.
OMG!!!!... I'm a dinosaur. :redface2:
Good grief... I'm changing my name to Barney since Old Guy is taken.
Sheesh, me and my old speakers and meters. Maybe I'm the one who needs a tube amp. :biggrin2:
Re: Altecs & tube amps......
I have a vacuum tube VOM meter on the shelf. It's nice too look at but I prefer my DVMs, some of which are 20 years old, or more. Nothing wrong with the 260, as long as it works!
Re: Altecs & tube amps......
So that explains why my 150 wpc Crown DC300A never got even luke warm, even at ear shattering volume with my A7's?
Re: Altecs & tube amps......
Probably does. If you need to light up a stadium with your A7s, then your Crown would be getting a work out.
Re: Altecs & tube amps......
Thanks, Panomaniac, When I found my A7's back in '76, down the street from my house, they probably had been sitting at that shop for at least 5-6 years. I bought them for about the price of a pair of JBL 100's . Thank God, when I mentioned it to people that new, they steered this naive stupid kid to equipment that rocked! I have been a graced non-believing man.
