Default Re: Avo EA113 faulty resistance range fixed - again

Peter, you’re absolutely right, and your keen eye has spotted the deliberate mistake... er, well, my mistake anyway. I uploaded the wrong picture in post #1. That was one I found whilst researching a couple of years ago. The actual picture of my meter is attached, together with a close-up of the repaired dry joint at the upper end of the 10k resistor.

My PCB is a conventional SRPB type and closer study shows that it definitely incorporates rivets for through-board connections. The instrument’s serial number is 1377.

The glass fibre board must have appeared in later production.
