Here’s another project I just finished at Rain City Audio:
This 1934 Weston Capacity Meter/AC Voltmeter was used to measure capacitors and the output of transformers for experimentation and troubleshooting. It only needed a good cleaning and one component replaced to fire right up and make some measurements.
