Cap block 6287-DU used in 116B chassis question
#1

The schematic list this as a .3/mfd block. I know it's really two .15/mfd. Now, it also list a 200/ohm wire resistor as part of the block. I didn't see anything inside it. This block had over-heated at one point, and all the tar was melted out. I'm also a little confused to which block lugs are used for the caps, vs the resistor. Can someone clear this up for me. Here's the parts listing.

My 650B used the same part. The bakelite block in mine looked identical to the universal type 6287-ODU. It uses two .15uf caps, one between terminals 1 and 2 and the other between terminals 1 and 3. IIRC, there was even a jumper on the outside between terminals 2 and 3.

For clarity sake, I'll number the lugs 1 2 & 3 from left to right, starting at the hold down bolt end. So, on mine there is also a jumper between 2 & 3. Just wondering if a resistor internally figures into any of this. I seem to remember talk of a resistor in one thread some time back.

There was no resistor in mine. And yes, you have the numbering correct. The jumper is correct between terminals 2 and 3 on the outside. Icon_smile

I think you are confusing part 6287-D with 6287-DU in the listings on Chuck's site.

The two are different parts. 6287-D is not used in the 116B as it an older type, not the "universal" type with six lugs which was adopted at the beginning of the 1936 model year.

6287-DU, listed as 6287-ODU on Chuck's site (same specs, just different wax used to seal it), does indeed contain two 0.15 uF caps, connected externally in parallel to make 0.3 uF.

(Edit: Also, the 6287-DU/ODU does not contain a resistor.)

Ed has given you the correct info, also. Icon_smile

Yes, thank you gents. That's what I did. The listing confused me.
