Mesa Mark 3 Parts Please Help

[boogiemanmark3]

Hey guys i was having a serious problem with my Purple stripe. My clean and lead were basically dead. I sent it to a tech guy and he has diagnosed that its the "photo coupler" also known as opto-isolator or optical isolator, optocoupler or photoMOS has gone bad. Apparently these control the switching and gain stages or something. anyway the amp uses 8 of them which he says i should change all. The amp uses 3 of VTL5C1 and 5 of VTL5C4. I live in Trinidad in the caribbean and we dont have any in the country. Can you guys help me find somewhere i can source these online to send to my skybox. I will greatly appreciate it, my amp has been down for months trying to figure out the problem. Thanks again.
