There have been a number of books published in the UK which might help. Look
for books on measuring instruments or speakers, both of which use magnets.
Those published in the '60's are probably most useful. I recall sections on
'charging' magnets in these.

Avoid 'magic' thinking, i.e. assuming there is some magic trick known to
few. In most cases, whatever you try will help and if it doesn't, figure out
HOW to figure out WHY. That's how most items are 'designed' anyway.

What rating PSU should I use on a system which has an Athlon 2400+
with a modest graphics card (old GeForce2 MX 32MB) and 768 MB of SD-
RAM. Unusually, it will have *SIX* IDE internal hard drives.

All the rest of the system is pretty normal with no overclocking on
the cpu.

Would a decent 350W PSU be enough? I am thinking of this Nexus PSU.

I can't comment on the power requirements, but I can say the power supply I
have is excellent. Its the Nexus NX 3000 (300W)and it really is quiet! If I
stop the other 2 fans in the system, I can only just hear it in a quiet
room! This power supply has a normal sized (80mm or 92mm?) fan and it is
quiet, so the big 120mm fan should be practically silent.

As for voltage regulation. I can't say if it is good or not (anyone
comment?), but I get the following readouts in my hardware monitor:
3.3v actually reads 3.312 or 3.328
5v actually reads 4.945
12v actually reads 12.096
-12v actually reads -12.196
-5v actually reads -5.005
5vsb actually reads 5.072 (don't know what vsb is!)

With 6 drives I'd go with a larger power supply, get at least a 450W
supply or even larger. An Antec 550W supply is only $108. You don't want
to waste your time hunting down system glitches because you saved 30 bucks
on a power supply.
 
Eject is on the right
you push it in, and FF and Rev. operate vertically from a lever which
tilts up or down on the left.

Bad news, it sounds like the ones I have won't work. These all have the buttons
underneath the tape door. Apparently they're all post 1983. That doesn't mean
the motor won't work. I'll have a look at one and see what kind of numbers are
on it.

Most of these radios need those hard to get output ICs, in fact I worked on
alot of these at one shop where the previous audio guy had a setup with a
common negative for the speakers. Blew out every single Delco he worked on. I
made a bunch of money fixing them, but the company lost. The chips might have
OC and short protection, but not amp to amp, and there's a left with two BTL
channels and a right, so each radio needed both.

When it shutdown cannot restart by pressing power, you have to unplug
for some seconds then replug to get it start again.
Has anyone seen this before. Your help will be appreciated.
I hope you can patent it.

You really can't have too much, but you can have too little.

When it comes to power supplies, I would just get a good name - like Antec
True Power, around 430 watt to be safe.

That's too much voltage. The extra power is a secondary result, of
course.

Go for a cheap Sparkle / Fortron branded PSU of the region 350-450w.
My sparkle 300w has been heavily loaded over the last 3 years and still runs
cool + quiet.

i know very little about pwer, but from what i know a 350w will be ok, a
decent one though, i have a cheap one and i keep getting IRQL errors, im not
sure if they are related to the PSU or memory, but someone at uni has told
me a 400w PSU is reccomended with all AMD Athlon XP's

Hello- I would like to get some feedback from those who tried this...
how easy is it to record a VHS tape on a DVD in these combo units ? If
I put a DVD and play the VHS tape, would the DVD record ? How is
quality ? And do these units usually have editing ability ? Thank
you.

If you find that the trouble is the tuner,I can recommend a very good
tuner repair Co.
It is
Tip Top TV&VCR
18441 Sherman Way
Reseda, California, 91335-4217
Talk to them at 1-818-345-1974.
They charge $27,free shiping and handling (USA).
On popular tuners,such as Samsung they usually have tuners on hand
already serviced and can ship right away.
They can send you a list of the tuners they service. (787) types
and more coming.
This usually is less than half the price of the tuner purchased
from the Mfg.
I usually put the tuner in a "bubble bag" and ship it regular mail
and within a week or ten days have it back.(and that is across the
cokuntry.) Fast overnight delivery is available. ***** Service.
Hope this helps.

It is a little hard to identify magnetic polarity of a magnet. I'm not

Yes, that's right. The North pole on a magnet is the one that points
north, so the pole that's near the Earth's north geographic pole is
actually a South pole.

It's a bit late right now, but I'll try to do some further testing tomorrow
and get back to you. Thanks a lot for your help!!!!

In a quick note, the scope seems to work fine after I press the trigger
button to get rid of the error, but after about 3min the screen shuts off,
if I move the position up and down, you can see a VERY fant light moving.
You have to really look though and if you didn't know any better, you
wouldn't think the scope wasn't on. All the other lights remain on. But if I
shut it off and turn it back on, the scope works fine again (still with the
error), but this time it goes off a lot quicker. My GUESS is that the heater
voltage is shutting off, but I don't know.

Thanks again

I have a Tek 2465B that is giving me a 'test 05, fail 42' code on turn
on.

After I clear it by pressing the A/B trig I believe, the unit seems to
work
fine till about 10min later the picture seems to fade off. I'm not sure
what
symptoms it has just yet because I haven't had a chance to screw around
with
it, but I was wondering if the error code is tied in with the problem I
see.

If anyone can help me, please let me know. I'd like to get this up and
running soon.

Thanks in advance!




Hi,

'test 05, fail 42' means: Test05 is main board, ADD mode tested.
fail42 means: positive level above upper internal limit.

So either the input amps are damaged or (more likely) you need a
recalbiration to this problem solved.

The "fade off" is more serious problem: Do you get a (compressed)
display on the screen when you press "beam find" button? If yes, it
might be just a problem with the input amp.
If not (more likely): U800 is the "magic circuit" that more or less
often tends to fail (== well known failure). Very hard to get
replaced.

Check Google for "tektronix 2465B problem" and you'll see lot's of
threads covering that topic.

Good luck!

hth,

With that many Hd's I'd be thinking about dedicating one good psu to
the motherboard and the optical drives/floppy and using separate
supplies for alll those Hd's.(maybe 2 drives to a psu rated at at
least 350-400 watts.)
Depends on what type of computing you'll doing and how intensive too.

Right! I use a standalone playewr for viewing and dupe the dvd's using
dvd shrink 3.1(from which all the high quality tapes can then be made
I want.) just by hooking up video/audio cables from the player to the
vhs machine.

supply or even larger. An Antec 550W supply is only $108. You don't want

You don't want to waste $30 for nothing, either.

Yes you do. The lowest rated supply I use for Athalon systems is 400
watts, and that is only with one HD.
Anymore and I go with a 500 watt.
Believe me if you really try and do any serious computing loads with
an under rated power supply you're asking for serious migraines.
