I need a little help from EE guys.

[tsfarley]

I've looked on 20 different Google reference sites and tried Google Lens and can't really quite figure out how to read these resistor values.
is there a std name for these types?
from 1982 HP analyzer.

is there a std for left to write reading values? which end to start.
1 i tried i got black, brown, black, black, green. correct ?

thanks in advance

if you have a multimeter maybe you could measure them and get some idea how to read them after that. Just realize, it's possible they aren't even resistors. They look like "dog bone" resistors, but in a 1982 piece of test equipment...??? Makes no sense. Dog bones are an antique type of resistor that probably weren't used after the 1930's. I'm going to go with axial inductors, look em up, I'm pretty sure that's what you have there.

thank you. I will do both !

If these are tubes, then most likely they are capacitors.
There is silver under the varnish on the outside and inside of the tube...

Ceramic tube dogbone capacitor. Temperature compensating. Is a definition I found. Searches are terrible.

 

[tsfarley]

Thank you all for the help and replies. they measured nil resistance on the meter i checked them with. The meter had no lower resistance ranges. So I'm believing they are not resistors, but capacitors as suggested.

 

[TheDoode]

If they have almost no resistance, they are not caps. Caps appear like open circuit to a multimeter, with infinit resistance.
I would expect inductors then.

The items pictured are neither resistors nor capacitors. They are inductors.

Time for more coffee.

 

[Findm-Keepm]

Tubular Ceramic (Dogbone) Capacitors. White body - 500 Volt DC rating
Color codes for such follow the standard EIA /ECIA color code scheme, read the color code from the TC (temperature compensation) color code end. All your capacitors have a black end, indicating NP0, or negative-positive zero change with temperature.
I've attached a doctored photo showing values. Note you have two identical value capacitors pictured.

Tubular ceramic caps are still sold, but rarely used. They rarely fail, so demand for them is low.
Surplus Sales of Nebraska, Talon Electronics, and a few other boutique vendors offer them.

The definitive color code chart.

The readings OP posted of his components indicates that these are probably not caps. They show 0 resistance.

If these have a tendency to fail short circuited, it would still be possible. But I would assume they are inductors.

 

[adam mizer]

He said NIL resistance none or actually nothing. No measure whatsoever.
Not 0 value.
An inductor will show resistance everytime. Thats the design (wire coil, air or on magnetic core). Henry scale.
Most meter leads also will add resistance to your measure, I see 0.2+ extra with most leads even Fluke leads.
Best meter I had was micro resistance meter with double lead wires reasonably thick and inserting a small current and measuring resistance.
Usually you can measure some resistance with a capacitor and it changes as its charged from the meter battery but now what were the spec's of the meter used to measure the value?
