And if someone would simply look at their own spool of fishing line and
say the brand name is "xxxxxx" and is sold as item number (or UPC code)
"xxxxxx", I'd probably be awaiting my order from an online sporting
goods store, or possibly already purchased from a brick and mortar store
and I'd already be restringing my radio right now. Instead I continue to
read you and others whining about my posting on this newsgroup.
 
I cant make it any clearer that I know nothing about fishing, and that
the line sold in the stores is rated by weight, not by diameter, and in
most cases the material it's made from is not even listed, or if it's
braided or solid. And with all of it encased in sealed plastic
containers I cant just choose by feel. All I see are a bunch of plastic
'donuts' hanging on a rack.... That leaves me two choices. Either begin
ripping apart the packages in the store, and probably get arrested for
doing it, or spend $500 to buy every package on the shelf, so I can tear
them all open at home and discard 99% of them, or maybe ALL of them if
none will work.
 
Take a look in a mirror and you will see who the real whiner is, who

Dealing with you is a bit like nailing Jell-O or making sense of Donald tRump. Both dubious activities with little discernible reward.
 
I, amongst others, suggested that you "bring a bit of the old" with you for comparison purposes. And that within considerable margins, thickness is flexible. And that there are thousands of different radios, with more than a few line-weights possible. WHICH MEANS THAT YOU WILL HAVE TO THINK FOR YOURSELF.
 
The problem with prescriptive (rather than descriptive) advice, is that when (not *if*) you screw it up, we own it. No such thing here. You can figure it out in less time than it takes you post again.
 
NOTE FOR THE RECORD: WalMart sells all sorts of line in clear plastic shrink-wrap, so the gauge is entirely and easily visible. But that does not fit your view of the world, does it?

OK, I get it; you want us to do your homework for you.
 
So, I Googled Walmart fishing line, and one of the lines they sell is "Tuf-LINE". Then, I Googled *that* and found this:
 
https://tuf-line.com/product/braided-dacron/
 
If you need some thinner stuff, I found this (again, using that devil's tool - Google):
 
http://www.eposeidon.com/kastking-fortis-braided-fishing-line
 
If you scroll downwards (Google "scroll") you'll see they list the diameters of each line they sell. You even have choices of color!
 
But if you're holding out for Trevor going less than his last offer of free, I would take it as I think he's bottomed out...

You may think you need 0.5mm as 0.5mm was there (do you actually have a vernier caliper? Doubtful). But the reality of dial string, with specific reference to Zenith TransOceanics is that anything up to one full mm will be fine, as modern Dacron will take knots better than vintage string - also discussed. Again, had you thought of taking a bit of the old with you, you would rapidly find what you needed. Vintage dial string was measured in gauge or fractions of inches, by the way, nor do they translate exactly to mm. Nor, in fact, would I trust you to be accurate in needing 0.5mm stuff.
 
See, this is the thing, were you to have any initiative rather than demanding to be spoon-fed with prescriptive advice, you would have filtered out: LOOK. FOR. WOVEN. DACRON. FISHING. LINE. And: TAKE. A. BIT. OF. THE. OLD. WITH. YOU. And, magically, you would have found what you wished in short order. Or, spent $6.00 and gotten the stuff from Australia. But, no, you want a UPC and brand name. And, when, as is very likely, it turns out to be not exactly what you expected, you would have someone handy to blame. Not gonna happen.

The old fashioned black braided Dacron line is what you want, in about a 30 pound strength. It used to be the cheapest line you could find. Only kids using worms for sunfish would use it. Oh, and squidders, sometimes.
 
Be very careful with modern fish line. They sell something called braid (Spiderwire, for example) which will not work at all. It is very very thin for it's strength, difficult to tie, and abrades like crazy. I use some because it casts a mile. But it would not work in a radio.
 
Rather than go to Walmart, I'd go to a real bricks and mortar sports store - not a chain like Dick's, although they might have it, but something more specialized. And ASK!
 
Squidding line is the same thing, I think. Also mason line at Home Depot or Lowes is pretty close, might work.

I'm not sure you can use a fast rule like that. The two links I posted for oldfart@tubes.com show radically different diameters for the same pound weight.
 
This company:
 
https://tuf-line.com/product/braided-dacron/
 
Shows their 30LB test as 0.712mm and this company:
 
http://www.eposeidon.com/kastking-fortis-braided-fishing-line
 
shows their 30LB test as 0.25mm
 
Best think to do is check with each manufacturer and pick by diameter not pound weight.

You remind me of a women I once met. She was known as "Dick Teaser".
She would meet a man, talk real big, promise him love and happines,
fame, wealth, and great sex and beyond. Then she would take him on a
date, and get him to spend lots of money on her. After that, she would
take her clothing off, expose all her goods, and as soon as he got
really excited, she would say "Not gonna happen", and walk off with
another man, (and do the same thing to that man).
 
But she always had something to offer...... lots of false promises, lots
of meaningless words, with nothing worthwhile to back them, and nothing
useful to offer anyone in the end.
 
You remind me of her in so very, very many ways.
 
The only difference with you, you never turned me on, got me excited, or
took one cent of my money. And with you I can plonk you with one push of
a button.....

This guy is an amazing piece of work. He can't figure out how to order from
ebay without buying from the most expensive seller and then he gets mad when
people express frustration in trying to help him.
 
What is wrong with this guy Oldschool?

Yes, that's what I'm trying to explain. That kastking is called braid but it's the modern stuff, not the old cheap line.
 
It's okay for fishing but you absolutely don't want to put it in a radio at any strength or diameter. It's super slippery, hard to tie a knot that will hold, and it has no abrasion resistance. But it's diameter is tiny so fish don't see it, and it casts very well.

People, learn to do the math.
 
600VDC/2.828=212VAC, so the 275 volt rated capacitor would be equaL
to a 777VDC capacitor.
 
2.828 is the peak to peak factor on a RMS sine wave. That is 1.414
volts peak, on each side of zero

I started working with the SMD parts a year or so ago. I decided to
stock up on some from ebay where you get strips of 10 each of about 50
valuse for a couple of bucks.
 
In this assortment were some 2.2 and 10 uF capacitors. For the most
part capacitors I am used to working with valuse round 1 uF and up are
usually polarity sensitive. Are the the large values non polar like the
smaler values ?
 
I have not had time to look at them under my microscope to see if they
look different.

I'm not sure I understand your question. Whether a cap is polarized or not
depends on the type cap. Tant's and Al are polarized (in general) and ceramics aren't.

If they are MLCC, the capacity can be quite high maybe even 10uF these
days, but very low V and a susceptibility to metal migration it PbF
soldering temp requirement fracture the ceramic at laying

I have read about the need to slowly heat the capacitors to keep them
from fracturing. I doubt I will use any of the lead free solder, being
in the US and this is just a hobby for me. I have a spool of some .25
and .15 solder that is 63/37 so should be good for life with that.
 
The listing does not say what kind of capacitors they are, just the size
and SMD capacitors.
 
The 2.2 uF is rated for 25 V and the 10 uF is rated for 10 V,, most of
the others are for 25 or 50 V which is more than most circuits I will be
dealing with.
 
They probably come out of China and may not be very good quality, but
for the price and my hobby usage I thought it may be a way to have a
stock on hand. I try to keep many small parts on hand if they are not
too expensive. Never can tell when I may want one and don't want to
wait on the mail from Digikey or Mouser, evenif it is only a few days.
Wouldn't surprise me if many of the electronic items don't come from
over seas. Some very good,, some not so good.
 
I remeber around 1970 while in school we took a tour of a TV studio and
they were telling us how the Japan cameras were better than any other at
that time.
That was still back when many people thought anything comming out of
Japan was no good. Maybe some of the China items will be the same way.

That may be the key. The listing did not say what kind of capacitors
they are, just SMD and the value and voltage rating. Whatever they are,
they are probably the same material, so the larger ones won't be
ploarized either. I did notice the voltage on them is only 10 volts
instead of 25 and 50 like the others.

If the cap tests shorted with DVM it is obviously bad.
 
If the caps test good with DVM it may be good or it may be bad under load.
 
Best test is to buy a cap that is close to the required value to use as a test.
 
If it works, buy the right cap and be happy you had an inexpensive repair of an expensive machine.
