Hello, my name is Fernando, posting from Argentina (Y). I wanted to know if you know a source to buy a new USB board for a Tascam USB-1800. I see a lot of people with problems with that board, so I guess there is a problem with that part, and I hope Tascam sells a spare part to replace the whole board. Tracing a fail in such a small thing will be extremely time consuming, I think it doesn't worth the time, I see easier to replace the complete USB board. Thanks for your help. Greetings from Buenos Aires !
