Ampex ag 440 Electronics Unit with Cards.Nice shape as you can see from the pics. This is from a 440B but the A and B units are interchangeable. I had this as a spare and it worked fine when I checked it probably 10 years ago. I can't check it with my 440C because the heads are not compatible with the electronics. I expect it is fine. Please wait for actual shipping cost before payment. Let me know if you have questions.
