Has anyone else seen this or are you familiar with a 4 digit resistor color code?
Or am I the only one that's out of touch?? lol

I ordered 1000 1/2 watt resistors for only about $20 including shipping from China.
Today I received these metal film resistors from a Chinese Ebay seller.
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=220078302667&ssPageName=STRK:MEWN:IT&ih=012

The price is great and the resistors are great too. Even the Chinese postal delivery was less than a week.

But the color code is a little different.

For example a 27K ohm resistor the US standard is a three digit-color scheme
Two significant digits and a third one as the multiplier:
ie 2-7-3 or red-violet-orn = 27 000 ohms

But these 27K ohm Chinese resistors are marked with four colors.
Three significant digits and a forth as the multiplier
ie 2-7-0-2 or red-violet-black-red 270 00 ohms

Are any of yoooze guyz familiar with this?

This is not Chinese color code, it is standard precision color coding. I'm surprised you don't know about it. What you bought are MIL specs precision metal films. Hopefully they really are MIL specs resitors and not just a cheap chinese knockoff.

As you found out, the code is 3 digits -for added precision, like 213K-. I use metal film resistors in my solid state audio design and in my dogbone resistors repro ( http://www.oldradioz.com/dog_bone_repro.htm) . Less noisy and much more stable long term. Especially useful for fix/stable bias. Also, they are about half size of comparable carbon resistors, Watts for Watts.

Thanks Syl... yeah you are right.. guess I just wasn't aware of this coding scheme...
According to the seller's info these really are 1% resistors.

I just assumed that 1% resistors would just have a different tolerance color band

I also bought another 300 pieces of 1 watt resistor from the same guy the next day.

Can't believe how wildly FAST the Chinese post is.... like 5 days or something.
Puts our post office to shame.

.. and piggy that I am...I already had a nice mixed wattage stock of hundreds of carbon composition Allen Bradleys from years ago.. and just last year bought two MORE nice little plastic stackable drawers full of metal film 1 watters that I bought for like dirt cheap $15 I think..
.. that company is no longer in biz... so I started seeking additional 1 watt and 1/2 watt sources in a wide range of values.... and stumbled on this great Chinese seller.
Now I have enough resistors to "resist" anything in the world..
...except the eventual Chinese take over of all US goods...lol

Thanks..

Hi Peter,

I just looked at total you paid including shipping...That is a good price. 1/2W metal films are 5 cents a pop here. You had a good deal.

Yeah, shipping is surprisingly fast.

Was "poking around" after the resistor research, and found out that you've been at the "sow's ears into silk purses" activity again to fund your overseas purchasing sprees.

Wasn't that Zee-nuts receiving the pizza slice cone replacement experiment ? Paint job on that unit was also showing a bit of masking lines.

AND was that blue portion of the Gil dial stock or had it been repainted also, and was the chromed ring surounding it ..stock? A photo of a red one I saw also seemed to have the ring...if it wasn't painted white instead.

Yes.. you'll find them all right here in a bunch Edd:

I hadn't noticed any obvious masking marks on the Zenith.. could be lighting.
.. and yes it too has a pizza spkr like a few others where it worked out just right as a solution to save a E.D. speaker.. esp when chassis mounting is the primary consideration stopping one from a simple PM swap.. y'know?
Both Gilfillans have the chrome ringded dial face as factory orig.
The blue one used the orig brown dial face where the Plum one had me totally recreate the dial from a hi rez scan and reproduce it in complimentary purple ( as in people-eater...remember?)
