I am on a quest to develop a liner as good as my Sidewinder that will work with cartridges.
I really haven't found anything that works with those things… I mean, I can kinda line with them with certain setups, but it definitely isn't fun or efficient.

But who knows.. ls t-tech going out of business or what?? (Patent infringement??)
swivel RCA?? how about a nice clip cord for a change?? Most repairs I have with premature motor failure comes from machines with RCA.
The jacks are so fragile, and it is a pain to replace a motor if it is soldered directly to the machine.
I could go on and on. I gave up on them. I just sell the Al Bro combo cord if somebody needs RCA.
uhg.
