I'm looking for a 1/4"TS Male to Female cable for connecting an amp chassis on bench to the speaker of a combo amp on the floor. 3 feet should be long enough. All I can find on google are cables for headphones or line level cords - nothing for a speaker. I recall an active participant on TDPRI that specialized in audio cables, but I can't recall the name and don't know if the company is still is business. Help appreciated.
