My bass amp stopped working the other day and I tried messing around with the input jacks, but still no sound. I took it in to a local music store and an employee briefly examined it and told me I needed a new Transformer for my Crate B40 XL Bass Amp. If anyone knows where I might find one online or has any links on where it is, please help me out. The serial number on the amp is B4XDCB0226
