By the way, what are RF signals?

Cable or antenna signals - channels, as distinct from video and audio
signals.

I'm sorry, I thought I read the sound did not work and had white noise in
it too. Since the sound works forget the tuner,it almost for sure is
working properly.

I got some original HP manuals from this guy for a very reasonable

the at sign is ematsuda - just trying to prevent spam, that's all.
Email him and see if he can help.

Ahh, I've found a fellow magic junkie.

Unfortunately, since there are commercial versions of this available, they'd
rather sell me one than accept my premise that my method is better.

How about 547? Does that sound any more familiar? ;-)

No, it's definitely a 647. Got it right here in front of me. Looks
to be one of the earlier ones, judging by the serial number.

Is this a solid state scope?

Yup, but it still uses tubes as rectifiers in the CRT supply. It's
kind of a weird hybrid, since everything else is solid state. I'm
guessing they either didn't have solid state diodes that could handle
the HV, or they thought the tubes would give a smoother output.

I should take some pictures of it... I get the feeling this was a rare
one. Even Google the Omniscient doesn't have pics of it.

Here are pictures, for anyone interested:

Now that it's working, I'll have to think about what to do with it!

That could be fun if there are no electronic types in the audience!

Even if there were, they might not sumble on to the trick.

Everything you want to do is very straightforward as long as you can
find space for the microcassette player inside the boombox. Large boomboxes
are mostly empty space so this shouldn't be a major problem.

The record protect is just a switch that can be removed or jumpered
as needed.

You could rewire any of the user control switches to select the magic
mode as long as your slight of hand is adequate so the audience doesn't
notice.

Yup. This seem pretty easy to do for an electronic technician.

Hint: avoid boom boxes with big buttons that go "clunk." Those are
mechanical and hard to tap into. Get the kind with pushbuttons
that are silent or which have a quit click. They are electronic
and easy to tap into.

Do this right and you could sell them to other magicians.

FWIW, there are chips that can store up to 90 seconds of audio. You might be
able to build what you want in a small cassette player which would look less
capable of being rigged.

One that has a small slide switch would be easy to operate and unobtrusive.

But honestly, don't you understand that we live in a world full of

Most of your intended viewers will be very un-impressed by this "trick".

It is a typical technical trick, like if you rigged a switch so the light
comes on in the living room when you push the switch in the kitchen.
Might impress a 4-year old child, but not anybody else.

Most people will immediately realize that you have wired the button, or
the boombox, in a less conventional way.

I disagree. Here is how I would do it if I had the time to take on
the project:

The magician stands on the other side of the stage and calls out
instructions.

The boom box looks 100% stock and in the original package.
The magician asks for an audience member who is an "engineer,
repairperson, technician or gadget freak." He selects three
of them and asks them on stage to "watch for any tricks."

One audience member removes the boombox from a shrink wrapped box,
inserts the batteries, opens the box with the tape in it, "plays"
the tape (which actually gets recorded on while "playing." When he
stops the tape, the boom box turns back into a 100% normal boombox.

The engineer/etc. then does whatever tests he pleases to verify that
it's a perfectly normal boombox. It even has a "warrantee void if
this seal is disturbed" sticker over one of the case screws. Each
of the other technician/etc. audience members does his own test.
Give them a blank tape to use because the tape from the box has
the write protect tabs broken out. (the boombox ignores the write
protect. but only in "magic mode."

Optional: another audience member was asked to bring in his own
cassette tape player. He confirms that the tape plays the same
on his machine.

Optional: another audience member was asked to bring in his own
cassette tape. He confirms that the tape plays normally on
the boombox.

To reset the boom box into "magic mode" press play six times,
fast forward three times, rewind twice, and play twice. Or
some other hard-to-guess combination

The boom box goes out of "magic mode" and becomes normal only
after a tape has been played for 90 seconds without stopping
(assuming a two minute long message - adjust according to length.)

All this could be done with a Basic Stamp or BasicX stamp.

I fixed both monitors. It was a bad solder joint. Was making big plans
to go buy parts, and got fed up and just started poking around
intuitively with my finger on the back of the circuit board. I touched
the jumper that goes between pins 8 & 9 on the TDA1180P and instantly
it syncs up. A few minutes with the soldering iron and both units are
working. Sometimes it *is* simple.

It is pretty simple, but for one thing - it's very difficult if not

it's an up-market product and you are an authorised dealer, and such
information is almost certainly necessary.

It sounds to me as if you could do it simply by accessing the
microphone, speaker, and switches - no knowledge of the internals
needed.

Always try the easy things first. Always.

Thing is, that was a new jumper I just put on the spare monitor, so it
was quite unexpected that it was not making contact. But it was a case
of soldering a very tiny wire onto the back of a PC board where IC pins
stick out, so apparently getting a good weld was harder than usual. The
installed monitor with the old jumper had the same situation. 4 things
needed to mate: solder pad, IC pin, wire, solder, and I probably didn't
use the iron long enough in my concern about overheating the IC.
However, it was fortunate that it happened anew because I was
immediately able to know what was wrong with the old one!

Check with an appliance parts place. ISTR that they have 'universal' parts

It's the first thing to try. Hard to imagine any other possibility.

Hi!

This sounds like a "hum bar" and is usually caused by dried up
electrolytic
capacitors in the power supply.

Yeah, but why on a brand new set? That's the part I find really strange.

Hmm must have misread it, I thought you said it was 22 years old or
something. In that case I dunno.

FM is a bit more tricky than AM, but try Ramsey Electronics, they offer some
very nice kits, lots of radio related stuff. Also do a search online for FM
transmitter circuit.

This would be a perfect project for some random high-school student,
assuming they still fiddle with hardware. Ask me 30 years ago! 8*)

A couple of random thoughts:

Maybe have the input and record-override functions be radio, so you
don't have to open the box to add a microcassette, or use a
solid-state memory to hold the headlines data.

Ask other members of the audience to bring their own boombox from
home, so after playing it in yours you can play it in theirs.

Of course, there's always the sleight-of-hand of swapping the
cassette...

Sounds like a fun project, but you are on the wrong coast, I don't
have the bandwidth to do it in my spare time, and you can't afford my
normal hourly rate. 8*)

ust do a google or dogpile search for "FM transmitter kit".
There are several electronic hobby shops on the web selling all sorts
of DIY kits.

I had good luck asking for a free copy of my Fluke DMM manual some
time back(8060A)
They scanned it and e-mailed it to me.
If you haven't already tried it couldn't hurt to ask.
