That means a 50 watt SS amplifier will do better at 35 watts than
a 20 watt tube amplifier trying to do 35 watts,.
I wholly agree. However what happens when both are asked to deliver
2000 watts? But only for a very miniscule time, and average putting
out, say, 500 mW?
A 36dB transient ? You are joking yes ?
Hell, you are very unlikely to find peaks more than 10dB above average on** = exactly why you do not get 36 dB peaks above average on commercial
music recordings.

Its even pretty hard to find 36 dB peaks in live performances."John Larkin"
Any recording medium saturates at a reasonable, but not
extreme, level above average program level, CDs run out
of bits, vinyl runs out of groove width, mag tape
saturates, even live FM is deviation limited.
** = exactly why you do not get 36 dB peaks above

I believe the tubie argument is that between being able to put out say 80Arny Krueger wrote:

You fry the speaker.
And, in the case of his little 20 watt tube amplifier, even if there was
that much energy in the power supply and the plate resistance were
damned near 0, the output transformers would have long since
saturated.
I think that "Bret Ludwig" is just another alias for a Luddite troll that'sGet real!
He can't: his argument falls apart, and he can't have that, can he?
[ ... ]Since the cartridge you use has it's trackability limits, and the

Yes, as far as the signal is concerned, but if the cartridge crosses a
scratch or some dirt, there can be a large transient. Some phono
preamps take quite a while to recover from one of these transient
events.
If the preamp bumbles for a while, the event lasts longer than it needs"Barry Mann" <zzzz@zzzz.zzz> wrote in message

Only the very poorly designed ones. But I'm uncertain why you are
worried about the amplifier distortion levels caused by a "scratch or
some dirt". The whole transient itself is distortion. One reason why I
always hated vinyl.
I learned root locus stability analysis in the mid-60s.I think any discussion of tubes transistors and distortion should be
tempered with an appreciation of the historic shift in design
techniques.
For example, undergraduate 1950's and 1960's tube designers didn't have
Root Locus in their tool bag.
I think that it was Bode and crew at Bell Labs during the 1940's that"Barry Mann" <zzzz@zzzz.zzz> wrote in message

Coughanowr's book came out in 1965. Coughanowr received his PhD in
1956, so any precident-setting paper was probably published in the
preceeding 15 or so years.
