Very Rare Pair Ampex 3741 R2 Power Supply Unit for 350-2 Tube Mic Pre + Case!!!

Description

For sale is a pair of very rare Ampex 3741 R2 power supply unit for the Ampex 350-2 tube preamplifier mixer. As far as I can tell they are all original, but please study the photo and judge for yourself. They look clean, and in good condition. The case I believe is original from ampex, with the tag at the bottom with the model 350-2 (I imagine signify that these PS units are for those). The case is in fairly good condition given its age. I think the handle at the top is either missing, or it's a weirdly design carrying case. The lock on it still latch on securely, and the case is fairly sturdy. It has been moving around so please expect wear and tear, as I can't show all side of it. If you are concern please contact me before you buy and I will send additional pictures.
I have no way to test this without the preamp, so I am selling this for parts or repair. Please keep this in mind before you purchase. No return accept unless I send you a completely different unit.
