[Casual Observer]

Dear Sir or Madam (Elecraft List Members)

 

I am extreemly new to the Elecraft and CW community although I have built numerous Heathkits many years ago. I am hoping to get back into this hoby with the K1 and K2 kits.  My question specifically address the SP2 companion speaker that I am presently obtaining parts for.  Could you please tell me what are the: 

 

J1 RCA Mute,   and the 

L1 82mh,   and where I can obtain them.

 

Respectfully
