I have been a huge marshall user for the past 20 years. I have never been let down by any of the products I have used so far until recently. I bought the Marshall CODE 50 and one year in time something happened to the power circuit unit. I got it checked from the store "World Music" in BD, and they confirmed that the circuit is damaged. I need to buy the circuit but unfortunately, I cannot find it anywhere here. I even checked with Guitar Center in Vegas and they were unable to help me out with the matter as well. Any lead on where to buy such a circuit will help me a lot.
