About the best I could do to get a 'flat' response was to set the tone controls to this:

I am, but I'd also like to know how you measured the wattage.
Yeah, I get it, into a resistive load, but how was it measured?
by change in heat (delta T)?

Can you post a link to the service manual?
Unfortunately Fender have stopped freely publishing their service manuals on-line for some reason, I got lucky before they stopped. As for power output, this is measured across a resistive load, be it 4 or 8 or even 16 ohms, a BIG resistor bank that has to take the power. You measure the AC voltage (RMS) across the load with an appropriate meter that's good for audio frequencies or measure on a scope (on a scope you have to divide the Pk-Pk voltage by 2 (peak) and multiply by 0.7071 to get RMS value) then simple use ohms law . . V2/R (V squared/resistance).
So if you were measuring 40V RMS - 40x40=1600/4(ohms)=400W . . Easy really..

Is this clearer Killed_by_Death?
 
HA....thats almost exactly what I set mine to, except the Treble is about 10 or 11:00
Now that is interesting FirewalZ. I don't know if you have the horn on or off on your rig? Seems your tone settings correlate well with the measurements. I appreciate your comments.

Next thing to do is do some 'real' measurements with a microphone to see how my '500' fairs through the speakers.
 
A link to my claim? I don't claim anything. I either quote from information I have (right or wrong) or make my own measurements to see what's going on.

You made a dubious claim, then offered nothing to back it - it really does look like you're trolling, especially since nearly all your posts have been in this thread since your very recent join date... Why should anyone here believe you with nothing to back your claims?

^^^Agreed^^^ Anyone can state a claim and draw and post a graph. It was not so long ago that claims & graphs were rampant that Fender amps could not go below 100Hz. The truth eventually blew the lies out into space.
