[Heathkit] Heath SB-1000 question

[john]

Hi Walt

I'll chime in here, and I'm sure others will too.

#1) Yes, any similarly sized bare wire is fine... no special requirements!

#2)  You did right ,  and the proof is in the operation.

Enjoy it. While I never had the SB1000, I did have a AL80A which I believe 
is the same amp. Nice smooth amp...enjoy it!
