To save people from going through the headache that I went through. I have an older SVT cab with the 4 pin connector. What a nightmare it was trying to find a replacement speaker cable. I asked seasoned SVT players where I could get one and got nothing. I did a multitude of web searches and got nothing. So here it is: http://www.fliptops.net/catalog/index.php?cPath=25_65 And why were they designed like this? It keeps you from turning your amp off of standby if the cab isn't plugged in. Worth every penny.
