For example, most inexpensive DVD players use switchmode
power supplies so that the product is largely universal
for world-market power supplies.

**Well, yes, but their power consumption is in the order
of 10-20 Watts, not several hundred Watts. BIG difference.

Whether small or large, SMPS might have the potential exposure that Jon
mentioned: "They generate all kinds of high-frequency spectra".

** Wot irrational drivel.

Complete bollocks.

Reliability of SMPS is not as good as a linear supply either.

Depends how you define reliability.

** Massive Red Herring.

Ignores the plainly stated context.

OK, so the SMPS has a lot more parts than a passive transformer. I still
see plenty of fried transformers.

** Total irrelevance to the point, what fuckwit Arny the ** Congenital
LIAR ** claims he sees.

Peeeeeeuuuuukeeee ..........

You can't scare me with old wive's tales about SMPS - we've had them in
computers for decades, they are thoroughly commoditized, reliable, and
very cheap, They run up into the 500 watt range. Change a few windings,
diodes, and caps and there you go. SMPS have never been a major problem
when it came to making clean audio with a computer.

** PCs have a 3 year max, life cycle expectation.

Not 30 or 40 years, as is the case with tube amp PSUs.

So, yet another MASSIVE Red Herring !!!

**Yep. Remind me about the impedances which surround the
grid circuits of tubes and their propensity to pick up
unwanted EMF.

I don't think that grids of tubes are any more inherently high-impedance
than the gates of some FETs.

** Another Massive Red Herring.

There is no ASININE COMPEWTER GEEK as dishonest as one caught out
LYING.

In both of my examples, shielding is minimal or just about non-existent.

** Shame how they were chosen by YOU to be FALSE comparisons.

Go back to playing with crappy PCs, 60s tube radars and boxes full of clunky
relays - you asinine PITA old fool.

The planet has no need of any fuckwit, born again, Septic Tank, criminal
pigs like you.

Drop dead.

OK, is there anything in the advanced materials horizon,
superconductors, etc. that is promising for re-inventing the classic
transformer? If cost were no object. Ok so Neodymium is nothng new:

http://www.chemsoc.org/viselements/pages/neodymium.html

But when someone began using it in speakers recently a whole lot of
possibilities for lighter products opened up.

Is anyone aware of any advanced physics research going on in
transformers that looks promising on the weight front, or that may use
a cheaper commodity than copper?

Here's a switch mode replacement for the *output* transformer:

http://www.davidberning.com/

Check out the Patents and the White Papers pages.

There's also a link to another company that builds an automotive version
of the Berning EA230 tube power amp under license, using a switch mode
power supply IIRC.

Once China and India begin winding
large sub-station transformers at the same proportion the developed
world has, its affect on copper will not make it any cheaper...

How about output transformerless tube circuits? Has that research
been exhausted? Can a speaker be made that will not exhibit impedance
changes at varying frequencies to make OTL possible, at least in the
guitar freq response range? Surly one can wind a speaker with the
proper DC impedance to match a tube, but doesn't back EMF wreak havoc
when the motor moves?

If you had to design a tube guitar rig (signal path only) for space
flight it would have to be light. You guys are giving up too easily.- Hide quoted text -

Only 10 lbs for 2 channels, a mono guitar rig could conceiveably come
in at 6 or 7 lbs, which is the same weight as the lightest of the new
high power class D purse-sized mini-heads like Fender Jazzmaster or
Acoustic Image Clarus.
