Hello all! I'm trying to sell my Manley ELOP compressor and I keep getting this question from potential buyers - "Transformers?" That's it, that's all they ask, just, "transformers?". I have no idea what they mean by this. I assume it's "does your Manley ELOP have transformers", or, "what kind of transformers does your ELOP have". I've tried responding and asking what they mean, but no one responds back. I guess they think if I don't have this information I'm not a very credible seller. Fair enough. Looking in the manual for the unit it says the XLR inputs have "Transformer Couple Input" and the 1/4" says "disconnects transformer and xlr input". So I guess it has transformers...can anyone shed some light on why this is so important? Thanks so much..
