[Heath] Need info.............

[Jeramy Thibodeaux]

Ed,

I can see where the confusion comes in as this part number has been assigned 
at least two different values.

SB-220 Amplifier
Part Number 45-78 is listed as 9uH RF Choke

HL-2200 Amplifier
Part Number 45-78 is listed as 10.3uH RF Choke

This does make me wonder where else this part number was used and I don't 
even want to speculate how this happened but it does create a dilemma.

If you want to be absolutely sure of the value, Neil has the right idea by 
stating that the part should be measured.  However, I feel this may be 
easier said than done as it does require a few pieces of test equipment that 
many hams may not own.  With parts count minimum orders now days it is 
almost impossible to build a cheap circuit to help in this situation either. 
These kits were designed to be put together and operate with little test 
equipment and once working they are almost bullet proof.

I have never owned either of these amps but do wonder how critical that 
value is in circuit?

Wondering what others have to say????

If all else fails, measure or figure out the current and choose a
replacement of the same physical size. You'll be real close.
