By all accounts, this mod purports to be true stereo if you read the copy. https://britishaudio.com/colle…-300w-stereo-modification
I just got the mod and received it today. I put a ping pong delay on and it seemed to be coming out of both speakers at the same time - i.e., it didn't move back and forth.
I'm fairly certain I need to have my output set a certain way. Is there anyone here that can point me in the right direction?
