[sdiy] RANE MP24Z

[Nathan Reeves]

ok thanks dave!

  doesnt hurt to get a second opinion.....

8^)

also, i found that i have rosin core and silver core!  yay!

can i use the silver to retouch the whole board?

what are the advantages?

better life?  more stable connections?

i heard silver oxidizes more so than the rosin based stuff

sounds like i should use whatever type of solder is used from the  
factory.....

both are radio shack grade though lol!

cheers!
