We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Owain
saying something like:

Oh, I don't know. *You could be getting on with something

We were somewhere around Barstow, on the edge of the desert, when the

saying something like:

If he's got any nous, said electrician will charge you special audiophile
rates and ensure he uses degaussed pliers, cutters aligned with the local
magnetic field and balanced consumer unit labels.


Ah but, said labels have to be written with a rare-earth-tipped
ballpoint else the stray fields around the customer's wallet/head might
be disturbed.

+1 here on that. Those nasty silicon rectifiers with their harsh,
fast nanosecond switching will place severe stresses on your
precious audio equipment during start up, not to mention generating
troublesome radiation of noise from those ugly sharp switching
transients. Using a 5Y3 will solve these problems by applying HT
gradually as/when your valves are ready for it and, since it is a
valve, your HT noise will sound much nicer...warmer and more
soothing.


Whilst the 5Y3 will be expensive, short-lived, inefficient and can
cause a lot of damage to other components when it fails. Of course
silicon rectifiers don't actually cause "severe stresses on your
precious audio equipment" if the system has been designed with even a
modicum of care. Nor, for that matter, will they cause "troublesome
radiation" either in a reasonably competent design.

If stress on components is your main concern may I recommend the
choke-input filter? It also provides a far better load regulation
than the common capacitor-input configuration.


Stress in myself is my main concern, rather than in any audio circuit...or
rather minimising it. One method is the use of humour, oodles of it...which
my original post contained.

That site is quite astonishing for the sheer amount of over-priced
garbage it has for sale. Although sadly I saw something on there I was
vaguely interested in buying.

Meanwhile, it doesn't even come close to this:

for sheer rip-offery combined with snake oil bunkum.

I recall gold-plated mains plugs and sockets being sold many years ago
to those foolish enough to purchase them.

If you retrace the thread back a couple of days, you'll find the mains
cables costing £2000 etc ...

This is just the ultimate OCD...

Align the slots in all screw heads so that the slots are parallel to the
earth's surface. ALL screws - screws fastening light switches to the wall,
screws fastening AC power sockets to the wall, screws fastening shelves to
the wall etc. Listen to some music for a short time and then move any of the
screw slots away from being parallel to the earth's surface and see if you
can listen to the same music with the same pleasure !!

Guitar amps used to operate EL34s in class a/b, afairc. Cooks the
valves, distorts like crazy, sounds, well, guitar-ampy :-)

Personally, I like amps completely flat, noise free, and generally
invisible. But that's just me...


It is horses for courses. An electric guitar played through a flat
distortion/noise free amp sounds....er...flat and thin. It is a common
studio technique to record from mics strategically placed around the speaker
of a "tube amplifier" to get that electric guitar sound.

I mentioned those back near the start of the thread, and was probably
responsible for most of the subsequent discussion!

MANY year ago? They still are - they're just much more expensive
now!
