The multimeter from my teen years, a Sanwa U50d. It has the standard ranges for the era. Sensitivity is 50uA with 20K ohms for DC and 8K ohms for AC volts. See note.

An infrequently used analog multimeter. I needed this meter for something but found resistance testing didn't work. It took a bit of work and a pair of new cells but it is working correctly again. July 2017.

Test Lamp 0217 1798

16 Feb 2017 2 367
I wanted a 12V test lamp while working on a car so I combined an LED and a resister off a scrap cct board, an old ballpoint pen tube, an old faulty multimeter probe, plus a crocodile clip and some wire from the junk box. I then used some solder, glue and heatshrink sleeving to put it all together. The photo shows the test lamp connected to the 12V output of a power supply. I expect this will also be used in working on electronics on the bench. February 2017.

The dip meter after repair, reassembly and testing. The coils for each band are stored in a drawer which clips in at the base. A crystal earphone is also there as the dipper can also be used a fairly deaf crystal set to test that a transmitter is transmitting on the tuned frequency. May 2014.

The dip meter had an intermittent fault so I disassembled it to do repairs. I found that the battery leads were badly corroded inside the insulation. This wasn't visible until I cut the battery lead. This photo was taken with the new battery lead soldered in just before reassembly. May 2014.

I bought this soon after getting my licence in the mid 80s. The dip meter had an intermittent fault so I disassembled it to do repairs. I found that the battery leads were badly corroded inside the insulation. This wasn't visible until I cut the battery lead. This photo was taken with the new battery lead soldered in just before reassembly. May 2014.
