Thanks for the replies,
Yes, I was using the rheostat on the sound board and not receiving any results. I am aware, through reading older posts, of the extra set of speaker wires tied up under the handle assembly.
I believe those are the speaker wires that come straight from the MPU if the machine is not equipped with the external sound card. I will try those next and see if they will produce any audio.
Scott, I'll get with Bob after Christmas about getting some parts. I definitely need the speaker, and I'll get the part number from the sound board while I'm in there looking around. I just know it's different from the last 6000 I put together. The Quick Hit had the knob facing forward and I could adjust it without removing the #1 Reel. This one has a short knob in the center of the board that can't be reached without taking the Reel out.
Thanks again and hope everyone has a very Merry Christmas!!
