Thank you for viewing! This is a Maxon OD-802. I previously acquired it as a used item, but I am selling it to organize my equipment. Operation has been confirmed, and there was no crackling. The op-amp is an RC4558P Malaysian chip. There are traces of tape that the previous owner had applied and removed, and there are areas where the paint is chipped, so please check the images. Also, please note that there may be minor scratches that are not visible in the images. The item is only the main unit, and there are no accessories. Please check the condition and understand that this is a no-claims, no-returns sale.
