      They didn’t galvanize or powder coat after cutting, bending, and welding. Really Cheap!

      Dave, you nailed it with the QC / QA stickers, operator 01 didn’t look at the chassis or perhaps their QA procedure says that a crappy chassis is a pass.

      That TxDAC does not look like a genuine Analog Devices part; it’s missing the AD logo, which is present on almost every AD part.

      i like teardown tuesdays ive done the like since i was a kid couldnt wait to see what was new, in 75 i opened one of the last tubed color television sets made in the usa the strange thing of the time was it had a color version of pong the video game built in i.c’s and tubes strange combo

      RUST?! Won’t be spending my money on any Siglent product after seeing this. I also don’t like the peel-back on the metal for making a hole for the ribbon cable. Looks like something I’d do on a home project I never expected to show off. For $1900 per unit, you’d think they could use a punch.

      They also used the wrong type of cable for the front panel USB connector. Instead of using a proper USB cable (with a differential pair and a shield for the signal lines) they went for a cheap flat cable. They’ll have problems with that.
