replacement diode for the 1n4001

I found it right away also it helps to use the right terms when looking for things ;) whats the 4 ohm resistor for ?

kool thanks. please tell me the colour code of the 4 ohm resistor and replacements for it

Man... Do a little research on your own....:wtf:
Use your common sense and do a Google search for RESISTOR
COLOR CODES...

We are not going to spoon feed you for life....:tsk:

If you were to shunt the 200 ohm pot with a 200 ohm fixed resistor, it would be 100 ohms by Ohm's law. It will be a little non linear at the ends but still within range. I use old dead LD's which are still a working LED but died from COP as a load.

the 4 ohm resistor is for a ddl driver, i now know the colour code but what replacements could i use for that 4 ohm resistor.
cheers
 
Thread jack... Hey Mike is that COP contagious :crackup:

Let's see.... you could use:-

1) 4pc 1 Ohms resistors
2) 2pc 2 Ohm resistors
3) 1pc 1 Ohm resistor and 1pc 3 ohms resistor
4) 1pc 2 Ohm resistor and 2pc 1 Ohm resistror
4) 4pc 16ohm resistor

and the list goes on....and on...

Use the 1.25 (Ref V) divided by current (that you want) formula
to figure out the resistance you really want...
