Your description of the problem exactly matches what I was experiencing. 
Yesterday I found another solution: hit the unit real hard and try again
- so far it worked every time.  It seems to be some kind of switch that
gets stuck.  Time to bring it in for repair.  I will then hook up my
microfan and see if I can drop the operating temperature to lecvel that
keeps the circuitry alive a little longer.

Is there any easy way to improve my radio reception.  The receiver has an FM

I had a similar problem and found that if I ran a wire from the outside of
the coax cable (on which the cable TV comes in to my apartment) to the grounding
lug on my preamp it solved the problem.  I guess the cable ground != my house
ground.  The trick also worked if I ran the wire to the screw in the middle
of a wall socket.  Does anyone know if there is a problem with this method
that I haven't thought of?

The Sony MD has a few real advantages over both CDs and Tapes.  Whether
people will consider these advantages worth the cost of switching to
another new format - we will just have to wait and see.  I'll be one of
the first people in line to buy the new players - and I'll probably buy
just about every MD pre-recored disk they come out with at first - just
to let the music companies know that they should invest more money in
the format.

The fact that there are two new formats - the MD and DCC - will
certainly slow down the acceptace of either format.  Many people will
wait to see which format wins before spending any money.

The bigest advantage of MD over CD in my opinion is size.  Not the size
of the player, but the size of the media.  You can put a couple of MDs
in your shirt pocket - but you can't carry a single CD that way.

I've taken my portable CD player on lots of trips, and the bigest
problem isn't the size of the CD player, but the amount of space the
CDs take up.  Because of the size, I usally don't take more than about
6 CDs.  With the MD, I should be able to take 2 or 3 times as many
disks.  To me, this is a big advantage.

I have a CD player in my car, and once again, the problem is with
the size of the CDs.  I keep my CDs in the compartment between the
front seats.  Along with the other junk I have in there, there's only
room for a few CDs.  But in the same space, I should be able to fit
10 or so MDs.  The smaller size not only means they take up less
total volume, but they will also be easier to pack into the crowded
space.  The CDs are almost too large to fit.

I don't expect MDs to replace my CDs in my home system - but my second
tape player will be replaced with a MD player the minute I find one
for sale in a local store.  And if the pre-recorded MDs are cheaper
than their CD version I will probably stop buying CDs.

I bought a 511 recently.  It was quite a nice A/V receiver for a video system.
I hooked it up with my TV, VCRs and LD.  I use a pair of Paradigm 3e for main
channels, a Rock Solid (from B&W) for centre channel and a pair of Radio Shack
Minus 7 for rear channels.  Maybe I could get better sound with better
speakers, but as it is, it sounded very nice when I watched movies.  As a
straight 2 channel system, the sound is not as good as the Hafler HD200 and
Adcom passive pre-amp ( with video switching) I used before.  But the surround
sound and other convenience features make up for the sound.  Besides, I don't
use the 2 channel set up any more.  Having said that, I would not recommend it
if you are going to use it as a audio system.  I would think that you can found
better sounding recievers.  When I want to listen to music, I always go back to
my main system which consists of Adcom (amp & pre-amp), Rotel (CD), Nak (tape
deck), Thorens (turntable) and Vandersteens (speakers).

Not owning a Pioneer, but another ld unit I'd recommend doing the following:
asking the salesman to see specifications...look especially to sampling rates

In my article, I was remiss in not mentioning my sources for the equations
I used. Usually, I am much more attentative to these details, but it was
approaching midnight, I was trying to bash EMACS at 2400 baud, my head was
awash with the fact that I just got my harpsichord back after 6 months of
refurbishment, etc., etc...

Anyway, the two major sources of relevant material are:

Richard Small, "Direct Radiator Loudspeaker Analysis," J. Audio Eng.
Soc., vol. 20, no. 5, pp. 383-395, 1972 June

Richard Small, "Closed-Box Loudspeaker Systems Part I: Analysis,", J. Audio

Loudspeaker Systems Part II: Synthesis," vol. 21, no. 1, pp. 11-17,
1973 Jan.

The situation with vented boxes is more complex, and vented system are more
sensitive to variations of the sort we are talking about. However, the change
in Qt that we saw in the analysis is far smaller than the unit-to-unit
variation in relevant parameters (such as DC resistance) that one typically
sees in well-made consistant high-end drivers. Further, there's far more
variation in the operating characteristics of, say, paper cone drivers simply
from changes in ambient relative humidity.

The point being is the phenomenon as stated and explained is effectively a
non-issue.

David Moran wrote to point out that small amounts of added resistance can
affect the frequency response at the ends of the cable due to variations in
the load. Now it has been reasonably established that relatively small but
broad-band frequency response errors are quite audible, and I suspect that
this phenomenon is far more significant to contributing to some audibility
effects. But the damping factor issue, please, let's let it rest in the
obscure peace it so richly deserves!

This is because a hifi VCR uses two sets of heads (well three if you want to
count the normal audio), one set for video (2, 3 or 4 heads for this I have
seen) and a set (two I think) for the hifi audio.

Well, if it did, how many buyers would know what to do with them?
If you use a standard linear model E-M propagation in a cable, for usual
(low) amp impedance, 2 to 8 ohm speaker impedance, your predicted response
for any sane cable will be that it is perfect. It might be possible to
construct a cable that would roll off hf or cause your amp to oscillate,
but surely that is a defect, not a feature.

Ok, the world is not linear, strange things can happen. What we really need
is a signed guarantee that, under certain circumstances a rep of the maker
can distinguish the cable from 12g lamp cable in a double-blind test. And
that if s/he fails to do so when challenged, the maker will refund a 
multiple of the purchase price. A multiple of 10 would be my suggestion.

That's probably not surprising.  Most 75-to-300-ohm baluns do NOT
isolate... one side of the 300-ohm balanced connection is connected to
the shield side of the 75-ohm unbalanced coax.  They'll pass ground-loop
current right through.

It's possible to buy isolated 75-to-300-ohm matching transformers, or
75-to-75 (or 300-to-300) isolation transformers.  Your cable company may
be able to supply you with same.  They're hard to come by on the open
market, for some strange reason... I haven't found a good source for
them.

> Do I need to do this to the cable into the stereo also?

If your problem is due to ground loops in the cable, you must isolate
the cable from _all_ of your stereo and TV components.

I don't believe it's ever a good idea to lift the ground protection on a
TV or similar consumer-type device without adding other forms of
protection.  If your TV should develop an internal fault which caused
line voltage to be applied to its chassis, the voltage would be returned
to ground via the only available ground-path... in this case, through
your cable wiring.  It might pose a real danger of shock or fire to you,
and to anyone else connected to the same segment of cable.

You could "lift the ground" safely in either of two ways.  One is to buy
a 110-volt isolation transformer, which will completely decouple the TV
set's 110-volt power from your local supply mains. The other is to
install a ground-fault interruptor between the TV set and the surge
protector;  it will shut off power to the TV if any leakage-to-ground
develops.

Tascam's number is 213 726 0303. Tascam is the professional products
division of TEAC. Tascam invented the portastudio with the model 144.
It had a 4 track mixer, 4 tracks on cassette, and Dolby NR. They refined
this with the the 244 model which took only chrome tape, ran at 3.75 ips
(twice regular cassette speed), dbx noise reduction and parametric EQ
(bass and treble had an adjustable freq). I had one of these - it was great
for what it provided.

The 246 has a six channel mixer built-in and other goodies. You will not
find Tascam porta-studios in HiFi stores. Check musical instrument dealers,
especially those dealing in synthesizers etc.. Anyone of them should carry
it. There are also numerous similar portastudios with varying amounts
of features available from Yamaha, Fostex, Vesta, Sansui, and others.
Check the Yellow pages for Musical Instrument Dealers and phone around.

A MiniDisc can hold about 1/5 of the data of a CD.  Hence, for audio,
compression is required.  For data, though, a MiniDisc-based system is
fine if a 100 MB disk with a transfer rate of 300 kbit/sec is adequate.

Hi Speaker Builder folks,

  I'm planning to use either Focal 5N411L (or 5N412DBE) or Seas 11FG-X
for small two-way sattelite. From data sheet, Focal drivers look like
they have very smooth response from Neoflex cone which is supposed
to provide good suppression for high frequency breakup and hence
less distortion. Although that is supposed to produce clean midrange,
Seas 11FG-X's paper cone is supposed to be lighter in density and
with smaller diameter, it's probably give faster and more detailed
sound. Paper cone may cause more distortion at high frequency breakup
though. 
   So would those of you who have experience with these two
drivers (either from your own design or commercial design i.e.
JM Lab Micron Ti, Proac Tablette) please give me your opinion about 
them? I'm interested in how good these drivers can sound potentially.
This depends on how they are used of course. That's why I need various
opinions. 

Thanks in advance,

TT (tt@swamp.cacs.usl.edu)

PS Not sure but quite convinced that Seas 11F-M which is similar to
   the 11FG-X is used in WAMM (early versions) and Theil CS3. And
   Focal 5N412DBE is the new version of the mid-bass in the SWAN IV
   project of Speaker Builder Journal.
