what does this resistor symbol mean?
« on: October 11, 2015, 01:18:09 PM »
This is from a German schematic emud 910. The small resistor looking symbols with the line through them and the numbers 160 appear to be next to it. Is this a 160 on resistor maybe 8760 ohm resistor or is it something else entirely?
~~~and did you exchange.......
a 'walk-on' part in a war.....
for a lead role, in a cage?~~~

You've got me. Looks like a 160 ohm resistor with a line through it, but it doesn't match up with any electronics symbol I know of.

To solve a problem like this I try to use actual context. Let's find the actual parts in circuit and see what they look like.

It crumbled to dust on both channels

Yikes, that does make it more challenging  :o

I would bet it is a designates  wattage of the resistor

It means that Germans have no clue how to properly draw a schematic  ;)

Whelp, since it's the cathode bias circuit for the power tubes and each is individually biased, and bypassed with a 100uf cap, its your power tube bias resistor and i'd hazard a guess the "line" is a 1 for 1 watt.
You would never need a 10 watt for a single EL84 tube, so i'd say 1 watt.
You might want to put in a 2 or 3 watt to be safe.

Look at the power supply resistors and see if they put lines or numbers inside the resistors, that would be the "key" to help deciphering(if they did that) There's bound to be a 1,2,or 3 watt resistor in the power supply somewhere.

I agree with Steve and voxACthirtee,
I believe that it relates to a Wattage notation.
Just below the EL84's is the EZ81 and power supply.  There is a 1K symbol with two lines between the 50uf's

Another guess would be that it's an indicator of the degree of precision, like the use of silver or gold bands.
