It smells fishy for sure. Probably someone got a piece of junk, and decided to buy a working one so they can return the junk one. Take a look at what 7-segment displays should look like. And take a look at the backside of the pcb. It sure looks like the display on the clock was installed backwards.

I got to be honest. The past few boomboxes I purchased did not end well. I would say 70% or greater arrive damaged. In fact, I rarely buy anymore simply because I know that hardly anyone bothers to pack like they should. I'm no longer shy about filing claims though -- not my fault. I've decided that if the boomboxes don't arrive like in the auction, even if it was a good deal to begin with, it's no longer a good deal when it comes bashed up. The SA-C07 that I purchased came with the power switch gone. Turns out it was inside the boombox. Turns out that the guy removed all (and I mean every last rear cabinet screw) and neglected to put them back before shipping. Well, those back screws holds all of the PCBs and the transformer in place. Needless to say, there's damage and I wasn't going to deal with it. I wanted 60% off or else he could have it back. The only reason it was even worth 40% of it's original value is because it was in very clean condition and the problems are internal. FF a month or so, I found a parts unit (center unit) that is not working right either but at least it appears unmolested besides a missing knob. It costed just about the 60% that I was refunded for the damage to the 1st one. Now I'm still not recovered from my surgery so both are sitting here. Cost wise, I'm no more than what I originally paid for the 1st one, but now I do have to invest time to repair it but at least I now should have enough parts to get a good working one. Then a few weeks ago, I found a 3D8H for sale. I have read that the 3D8H has better bass than the 3D80's I have that I really like, and I wanted to hear for myself. Made a ridiculously low offer of $38 before shipping. Well it arrived with a fist sized hole in the rear cabinet. The carton was only slightly bigger (like 1/2") around than the boombox itself. I told the guy I want $20 back of the $38 sales price or I want to return it. He asked if there was outward signs of damage to the carton. Not that it makes any difference, USPS isn't going to indemnify a shipment with less than 3" of cushion around the boombox. Anyhow he refunded the $20. Was it worth $18 + shipping? Probably. At least all the bits still appear to be there and hopefully it should respond well to solvent welding the plastic. If it was cracked anywhere near the front, forget it, I'm shipping it back. Only because the damage was isolated to the rear vented grill area. At first listen, I'm not impressed however, I do think the 3D80 sounds much better but to be fair, my 3D80 got a full recap almost immediately so maybe this 3D8H might get the same treatment, but only if I can save the rear cabinet. If not, I'll go no further. I'm too old, too far gone to do any more substantial repairs on stuff.
