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

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

I would guess its really a 1000 uuF pF
