Here is a quartet of Ampex 4020260-02 pre-amprack-mount “record/reproduceelectronic units” made to link up with the classic AG-440 series of pro taperecorders, one for each channel. The 440 was made from 1967 into the mid-1970s, and is still an esteemed deck. These came out of a late friend’s home studio, where they sat unused for the last couple of decades. I have no idea if theywork, or even how to power them up, so I am selling them as-is.The exterior shows wear, s...cuffs and some lightrust. Some screws are missing and some are non-original. All the knobs, plug-inmodules, etc, are present. The red plastic dome is missing from one of the “record”lights. I’ve only opened up one of these, and the interior looks unmolested. Each unit weighs 12 pounds, so they will amountto over 50 pounds for shipping. No reserve. I’vedescribed the item as best I can, and it is sold as-is, returns, refunds oradjustments at my discretion. I strive for fairness: Please check my altogetherpositive feedback. Payment by Paypal. Contact must be made in 3 days andpayment received within 5 days. Please check my other auctions.
