Ive been trying to get some info on the lineage of the 525 for a while, a friend of mine is claiming to have an original 525 without an output transformer which he is convinced is stock. Ive looked and cant seem to turn up much of any info about these limiters. Does anyone have experience with the old 525/ 525b/ 525c/ 525d? I would love to know definitively tthe differences between these models. Apparently there is a d version, however Ive never seen one.
