Hi all,
This raises an interesting point:
I've been building and repairing amps for five years now, and am on the cusp of trying to market one model -- nothing big-scale -- just enough to support my hobby. In any case, I have a design --40W from 2 X EL34 -- mainly designed for clean headroom. (It stays pretty clean up to about 75%, and never goes beyond a toothy crunch.) With every control dimed, it will screach, but backing off on any one of several parameters will stop it -- treble, volume, master (if engaged), or preamp boost. Now, I COULD make various alterations that would prevent this, however, any such change will negatively impact (albeit marginally) the overall tone in more moderate settings.
My initial inclination concurs with the quote below: 'so,what did you EXPECT?'
On the other hand, the fact that people are asking the question, and are clearly concerned about the behavior suggests that can't be casually dismissed.
So, any thoughts from the consumer perspective would be gratefully appreciated.
Personally, I'm inclined to simply put a prominent acknowledgement in my user manual explaining the problem, and warning that: "if you do x, then y..."
I guess it's not a real big deal, but to me that's like fitting a Porsche with a throttle governor . . . ;^)
Thanks.
Joe
