Incredible - mostly looks as if it just came off the assembly line!
Agreed, that supply is clean. It is weird about the corrosion on the fuses and no where else.
I am surprised that the maximum B+ is 300V. I would think +500V maximum would expand it's usefulness.

That's why you have to get a second NGU.

And the dots of paint on the solder, I haven't seen a lot of that over here. Is that an identifying mark to tell if tampering or repair has been done?

I have no idea. I saw similar dots like these on very rare other occations and was always wondering about their purpose.
Never had or used a Sinclair product. Seems I wasn't missing anything other than aggravation.
Hooo Boy, I snipped a big one this time (35kg/77lbs) and it's a Fluke! Please remember me to never set auction listing scheduled to end a midnight on a holiday.

The waveform on TP5 when everything is working correctly.
The 2 optocouplers on the DAC board.
Oh great, fixed, well done
But... but.... you changed everything at once so we will never know what the root cause of the problem was ! That is not acceptable on TEA!!
So it's 15ppm off then ? Don't know the specs of this thing but regardless, I guess it's nothing to complain about for a XX years old boat anchor that has not been calibrated in many years I guess...
It's official... We are finally 100% done with the old place.
Shed is moved; I spent a hour drilling extra screws through the frame into the base, but it paid off. Nothing moved so much as a smidge all the way over; not even at 70 kliks per.
House is cleaned, keys handed off, and ex-landlord said it was all fine.
And since our cleaning service bailed on us at the last minute due to COVID-related issues, we had to clean the house from top to bottom ourselves. But we saved almost as much as I spent on the rollback wrecker getting the shed here.

... so many things either worked or didn't when they arrived. If like me, you got lucky, the products worked well,

Just yesterday i felt the urge to watch again the "Micro men" movie... That can't be a coincidence

My guesses would be either to indicate tampering, or perhaps to verify QA, as in look at the joint then mark it to indicate that you have done so. During my house rewire I used a marker to draw a diagonal line on my circuit breaker terminals as I torqued the connections as an indication that I had used the torque driver on them and done the final tightening.

The 2 optocouplers on the DAC board.
So I went all out and decided to replace All the optocouplers and the NAND gates (U30, U32 and U38).
