[sdiy] neutrik 1/4 jacks

[Stephen Begin]

just curious as to whether anybody knows the difference between all the "Q"
type economical 1/4" phone jacks on this page

sorry, I probably should be asking a mouser representative, but I thought
maybe somebody wouldn't mind throwing a quick answer my way.  Also, does
anybody know what they mean by "solder tabs"?
humbly,
Steve
