What's .001 uufd ?

I'm trying to fix this antique black and white tv. There's a part in the tv that says .001 uufd on it. On the other side it looks like a domino with 6 colored dots. The dots are different colors, the thing is rectangular with a wire on each end. It is about

1 inch long a half inch wide and 1/8 inch thick. Flat package. I know it's not a chip or power transistor becaue this is a tube tv set. It dont look like a resistor. Capacitors are usually labelled MFD (microfarad). What the heck is uufd?

These antique electronics sure have some weird parts, even though they are built like army tanks. I wish I had a tube tester....... They all light up !

Another thing. I notice corrosion around one of the filter caps. I bet it's leaking. It's a metal can about 4 inches tall, 1.5 inches in diameter, and it has 3 leads on the bottom. (3 caps in one can) It reads:

80mfd 600v 10mfd 450v 40mfd 450v Where can I get a replacement?

I get nothing on the screen, but there is a loud hum coming from the speaker, which happens to be a the weirdest speaker I ever saw. It's got a coil where there would normally be a magnet and an extra set of wires going to the chassis. No parts look burned.

Try asking in the right news group. There is an antique repair group for radios but I know none for televison. Maybe someone in sci.electronics.repair knows?

uuF = MicroMicro Farads = Pico Farads. Rec.antiques.radio+phono group can help out a lot more - there are some TV restorers in there . Someone might have some things you're looking for.

You're right - there's no chips in that TV. But you best learn more of the parts in there - some might be knocking you on your ass - if you're not careful.

Just because "all the tubes light up" - doesn't mean anything. Any tube can light up and still fail to perform properly. Your issue - description "seems" to suggest a "Power Supply" issue ("maybe") - not feeding voltage to RF/IF/Audio stages and not enough going to the leg to feed the "High Voltage" section to supply the picture tube. Of course - with an old set - most anything could be wrong and it could also be multiple issues. But the best place to start - is the Power Supply from the AC in - checking voltages to see where they cease to be normal. A schematic would really help tracing voltages - hopefully you can read it. Taking voltages can be dangerous if you're not familiar with doing so. Get someone near you who has experience - if you have no experience, you/your family will be a lot safer for it. Getting the RF/IF/Audio stages of the set working may not be so tough - just hope the "picture tube" is still working to give you a picture! Good luck - and BE CAREFUL.

001 pF or uuF sounds like an impossible number. Stray capacitance will be higher.

I would guess its really a 1000 uuF pF

probably .001 microfarads, some old printing used an extreme left drop serif before the U of the UF.

or even a inverted M/m to signify the MicroFarad.

agreed, theres usually 250-600 volts at very substantial current scattered around inside this older units, and the older the insulation gets on those wires, the least it will protect u!

i applaud u for trying to fix this, you will be a "specialist" if you are successful, as most of those old timers are rapidly dying off!

antiques? heck we all become antiques after awhile ;-))

at least this kool stuff remains, we either get buried semi-intact or flashed into ashes!

Doesn't it go: Micro, Nano, Pico? so Micro = X10 to the -6 nan0 = X10 to the -9 and pico = X10 to the -12 so micro micro is X10 to the -12 or pico? and there fore .001 micro micro = ,001 pico which is not a valid commercially available value

Almost certainly microfarad. it would be 1 nF.

The use of 'MFD' was only ever a US phenomenon.

However 0.001 picofarads makes NO sense at all.

I was answering the "basic" question of uuF - and that was "before" i had my coffee. I wasn't paying attention to the actual "value". Due to the back ground of the poster - it "appears" he had limited electronics experience to start with. I'm more concerned with his sticking his fingers in a place - unexperienced, than a "Value" of a component.

Some of my first experiances with electricity.

My mother told me of the time I was spilling water in to the socket of a table lamp I had unscrewed the light bulb.

The second time was with a remote control bus I had which worked with a spark gap static transmitter. I had unscrewed the antenna and poked my finger inside while pressing the transmit button. I remembered this ocasion very well.

Watch out where you stick your fingers.

and download "TV Diagnostics II". It also contains color code charts. Cheers, Joe

Ah yes, our formal learning years........ I used to stick my fingers in Lamp sockets and turn them on - what a tingle! OR grab onto Antennas with a transmitter turned on. No wonder I've got such an electrifying personality! I produce sparks most of the time when touching metal or so on. Hmmmmmmmmmmmm How I miss those years! I'll have to try to relive some of those experiences for old time sake.

Sounds like you've got those units right. For some reason they don't seem to use milli- (10^-3) or nano- with capacitors.

I don't know much about old electronic stuff, but in the more recent stuff there are a lot of .001 uF (not uuF or pF) capacitors.

Isn't it amazing - how much we all "sort of" resemble or try to emulate - Uncle Fester - Addamms Family! I recall a toy store next to my house as a child used to sell a "light bulb" you could stick in your mouth to make it light up - like Uncle Fester. Those were the good ole days - "before" learning "safety".

I recall a time, I had an H.F. rig needing repaired. The damned volt probe kept slipping off the post with clip installed. I knew to keep one hand out or else. Well, I said to myself mentally (the angel on my shoulder speaking) - dummy - you're going to get lit up if you stick both your hands in there to hold those probes in place. BUT - (the devil on my other shoulder prodding me on) I didn't heed my own advice and I did just that - stuck both hands in. YEP - sure as hell - I got lit up. Served me right. Man, that tickled worse than the "Light socket". Didn't have to kick myself in the ass - the shock did a good enough job.

I still get a tingle now and then, but not like I used to. I take less chances. Too old to do that stuff now. Don't know how many more ticks the ole hearts clock has left in it, don't want to short circuit them.

It's .001 mFd, or uFd if you prefer. A value commonly found in older radios.

I can remember making a Jacob's ladder with a oil burner transformer, and sticking all manner of objects into the resulting arc to see what would happen - paper would get holes punched through it and sometimes catch fire, etc. One day I held a pencil by the eraser end (metal) into the arc. Of course, the high voltage traveled up the inside of the pencil and discharged to the metal end I was holding (duh!) Naturally, I didn't attempt THAT one again...

You ain't seen a Jacobs Ladder till you see this one that shoots 100 feet in the air from a 500KV. Go to: http://205.243.100.155/frames/longarc.htm Then watch the video called "This is the record holder for the world's largest unintentional Jacob's Ladder!".

Of course look at the others too. I love this website !!!!

By the way, I used to play with neon light transformers. They can really kick butt !!!!
