Hello! I have been testing out producing an amplifier using the TPA3125D2 speaker amplifier in BTL mode to double the power to a speaker. The design was based entirely on the schematic from the datasheet. The input and inverted input are provided via a TLE2074 opamp. The idea was to product a small but simple guitar amplifier. It is powered by a 15V 4A adapter salvaged from a laptop.
I built it once successfully then had issues with the guitar's preamp section and now when I try to power it up, I get a very rapid tick from the speaker instead. I have rebuilt it and am still getting the same ticks. Is there anything I can do to resolve this issue? What could be causing the ticking? I have provided the diagram of the prototype that I built on some veroboard.
