UTC transformer mix bus box stereo / dual mono for ssl neve api mixer UTC A-20

I bought this a little over a year ago from a builder on Reverb for right around $600. I wanted to run my mixes through some transformers for warmth and analog vibe. I paid extra to get these matched pair of UTC A-20 transformers. The builder explained that these would be great for the type of music I am making. It was a game changer for me to run my mixes through them.

Some people might not be able to notice a big difference but to someone who has been mixing for a while, it makes a big difference. I even started tracking individual instruments through them. My favorite thing to do is to run my mono snare through both of them by using a patch cable. It really just makes the snare fatter and crackier. It really is the perfect thing to get rid of the sterility of digital recordings. I've even ran a mix through them a couple times and it sounded amazing. The only reason I am selling it (at a massive discount might I add) is because I am no longer mixing or recording music for income so no need for the extra mile. I posted a couple of pics of these transformers for sale. They are not cheap. 550 dollars was the lowest and I'm not even sure they are matched. They are in way worse condition than the ones I am selling. Below is from the manufacturer of this box-

Custom hand built stereo/dual mono transformer box with vintage UTC made in USA line transformers, use for mix bus glue, sweetening & smoothing transients, adds punch, depth, weight and real analog harmonic color for use on mix bus, stems, tracks, inserts, after preamps and any other line level gear such as compressors, effects, synths, analog keyboards, samplers, drum machines, while tracking or in post production etc to fatten then up and smooth out transients over the whole tonal range very effectively gluing things in place. Makes mixing easier, less need for compression and eq.

They add a punchy low end, smooth mids, and detailed silky high transients, cohesively gluing your sound together. Passive, no power needed. Fully balanced in and out, line level unity gain ratio 1:1. Solidly built with german made XLR's and internal shielded wire.
