I have an _ancient_ laser which almost works.  It's a HeNe laser,
model 3100 from Gaertner Scientific (circa 1969).  It worked for a
while, but now has developed an electrical problem.

This laser, when you get down to it, is basically an expensive beer
sign with a couple of mirrors hung on it.  The tube does not run
continuously any longer.  It flickered for a while, and now it just
fires in bursts.

The power supply consists of 2 transformers, 4 diodes, 6 resistors,
and 2 big capacitors.  My first guess is that the caps have become
leaky.  Any tips?

It _does_ lase, when the tube fires.  So the optics are OK.

(Yes, I know that for $50 I can buy a semiconductor laser with more
power and a better beam shape.  That's not the point.)

I would be interested to see *any* power supply which needed
one side grounded ...

Since all of the equipment described (PC excepted) has transformers,
there is no problem.

In electronic workshops (TV repair and the like), the supply is frequently
(read that as REQUIRED TO BE - in the UK anyway) fed via
an isolating transformer - the whole point of which is to remove
the ground reference - both wires "float" w.r.t. ground - then when
you put your finger one one of them, there is no return path, so
you are less liable to be zapped.

Unless anyonme can give a good theoretical reason why any design
of power supply should require grounding (and I would argue that any
supply so designed is bad design), I would have no hesitation
is saying "plug it in".

If you are really paranoid, use a 110 -> 220 transformer, or a
220 -> 220 transformer, and ground one side of the secondary
(If you go this far, you probably also beleive in fairies ...).

	What I am planning to do is build an amp with trebble, bass, balance

speaker ports at the rear of the computer. The input will be from a 
sound blaster card that give 4 watt and plan to run this through the

bays 12 V to 30 V using a dc/dc converter.

Now the question...
	
	Now, I know that the drive lines have both 12 and 5 volt supplies 
and respective grounds for each but,	
	Can anyone tell me what sort of maximum current you can expect to 
get out of the supply line for floppy drives?
Any recommendations or comments welcomed.

I don't have specs for the 12A6 but I do have a suggestion: use
a curve tracer.  You will need two other power supplies for the
heater and the screen grid; don't apply screen power until the

As far as I know nobody's taking legal action, but the winds are blowing
that way.  The problem is that cadmium is a toxic waste.  The most likely
long-term solution is that nicads will be phased out in favor of gel-cell
batteries (which are basically lead-acid) or nickel-hydrogen batteries.

I'm planning to assemble an AT-class PC (finally junking the old XT),
and would appreciate anyone's wisdom on the pros and cons of "baby"
size versus full-size cases.  Note that I'm leaning toward a desktop
case rather than a tower.

Two of the concerns I've thought of are:

-are baby-size motherboards as commonly available as the larger boards?
-do they have the same headroom (for ease of installing add-ins)?

Any tips would be much appreciated.

	Also other things happen. Main difference between older tubes and
	newer ones was the quality of the seals between the tube and the
	mirrors on each end. Not just gas leaking out, but atmosphere getting
	in. Some things to note.

	Even if you get a gas discharge, (red glow,) you may not get lasing
	action.

	If you see a blue glow, (looking slightly off axis, and blocking
	the main beam,) this also indicates contamination.

	Many tubes I dealt with contained a getter, but also a black spot on the
	side of the tube which degassed more gas as the tube heated. For new
	tubes the spot was very black. For old tubes, it faded out.

	One last trick, switch polarity on the tube. Cook it this way for
	a couple of hours, then switch back.

Any capacitor filtering the output of the rectifier?

Also, I would have used a MOSFET (like the IRF511) rather than a transistor.
I suspect you are just barely getting enough energy to turn the transistor
"on".

Don't blame me if you fry something, because I've never gone this way,
although I have run lots of american equipment in England.
1) The frequency difference, 50Hz/60Hz. Basically, switch-mode PSU's don't
mind at all, the first thing they do is rectify the mains to DC anyway.
Switch mode PSU's will run off 50 Hz, 60Hz, DC, square waves, you name
it!. Transformers are more of a problem. Normally, 50Hz equipment will
work off a 60Hz supply with no problems, and I've never had any problems
with 60Hz stuff on a 50Hz supply. The transformer runns hottter in the
latter case, but not significatly. Waatch out for things that are tied to
the frequency though. Some older record turntalbes/tape recorders/LARGE
(14 " demountable) hard disks/clocks/timers use the mains frequency as a
reference. In that case you will have to get a modification kit from the
manufacturer. 
2) Voltage. 110 V stuff on a 220V supply either needs a new transformer, A
tap change, or a step down autotransformer. I've done all 3. The other way
is easier. First find out if there is a intenral adjustment for 110 V
mains. If not, check if there is a american model (or similar - going the
other way I fitted a British CoCo2 transformer in a Tandy CoCO3 that I was
going to use over here). If there is, buy the transformer, and fit it.
Othewise you can use a 220V socket in America. The problem is that neither
side is grounded, whereas one side of the 110V supply and of our 240V
supply is. This shouldn't matter really - the design should never
intentionally pass current from either side to the ground conductor. You
should use a Double-pole switch in this case though (in fact, you should
use one anyway!). Most suff should work OK at 220V neither side grounded.
Anohter nice trick. You can (If you have the schematics, and know what you
are doing, modify the input side of a 240V switch-mode PSU from a bridge
rectifier (giving about 340V on the smoothing cap) to a voltage doubler.
In fact the switches on most small switch-mode PSUs do just that. If there
is no switch, you can try anyway (By wswitch, I of course mean a voltage
selector switch, not an on-off one).
3) Video standards. HELP!!!!! RGB is possible (most monitors work at
either frequency, and of couse IBM PC type monitros work at 60HZz vertical
everywhere (except for those high-end standrds that use 70Hz etc). No
problems at all. TV/composite is more of a problem. very little modern
equipment uses the mains for any timing reference in the video stuff, so a
european video recorder will play into a european TV no matter what the
mains frequency is. Just don't expect to be able to record off-air

Huh?  Your math is fine.  What do you mean "doesn't work out correctly"?

Maybe what's confusing is that the way the power company charges.
Some charge $X1 for the first N1 KWH, $X2 for the next N2 KWH, etc.

Or is the device really using as much power as you think?  A light bulb
left on all the time will give you the right answer, but just because
a stereo amplifier is rated at 100W doesn't mean that's what it's using
all the time.  If you're not sure you may wish to measure the AC current
at typical usage.

Has anyone got plans for a switch mode power supply unit for a motor vehicle 
to power a couple of mean amps with vicious base so I can get some killer
music. Any replies will be greatly appreciated.

Please send replies to : eyal@shrike.und.ac.za

Thanks again.
