Great repair on such a useful tool..... It seems the switch doesn't have a lot of support and if used many many times the solder joints get weak and the switch wants to move around and eventually gets loose and the connection fails ..... I have the 2nd version with the newer chip , I got it from Ebay brand new for 40 USD .... I forget what IC chip is in there ......

In reply to Albert van Bemmelen.

It is a good meter but not be thing I do not like about is the length of the wires. According to the manual it can not be longer than 15 cm with is not much.

Noticed that you have the Anatek V1 Blue ESR meter with a Zilog ic. Curious how my ESR meter looked on the inside I noticed they were the same in version and construct.

My Anatek Blue Ring tester however apparently was already version 2 but probably much simpler to fabricate because it only contained a few simple transistors and 2 common cmos ic's instead of the special Zilog and other parts in the Blue ESR tester. Nice thing of this tester is that perfectly shows a short in any transformer coil. Even in small RF coils when we short the primary coil it shows immediately in the secundary coil, and vice versa.
