My Experience with Bristle Blocks on eBay - A Vintage Keithley Instruments 600A Electrometer Repair

As I began my search for a repairable digital display model, I stumbled upon an eBay auction that caught my attention. The listing was for a vintage Keithley Instruments 600A Electrometer, and despite its age, it seemed like a great opportunity to score a deal. With the starting bid and shipping costs adding up to under $40 USD, I thought it would be worth a try.

Upon arrival, I noticed that the meter had been previously used and showed signs of corrosion and electrolyte leakage. The auction photos revealed a lot of wear and tear, but I was determined to restore it to its former glory.

The first item on my agenda was to inspect the internal components for any obvious problems. Fortunately, everything seemed to be in good condition except for one broken wire connecting the 'Zero Check' mid-support terminal. A simple solder connection repair fixed this issue.

Next, I opened up the meter and began cleaning and calibrating it. The bezel of the meter was pushed in past the front panel, which required some careful manipulation to get back into its original position.

The auction photos also showed a lot of corrosion around the dual D-cell battery holder, so I ordered a replacement Keystone Electronics 176 battery holder, which arrived before the meter did. I also picked up a full set of batteries for the unit.

After receiving all the necessary parts, I spent some time cleaning and repairing the meter. With patience and dedication, I managed to get it working perfectly again. The end result was a beautifully restored vintage Keithley Instruments 600A Electrometer, ready for its next user.

Overall, my experience with buying and repairing this vintage instrument on eBay was a positive one. Not only did I score an incredible deal, but I also learned some valuable skills along the way. If you're considering purchasing a used electronic device online, I would definitely recommend doing your research and being prepared to put in the time and effort required to get it up and running again.

In conclusion, my experience with bristle blocks on eBay was a successful one, and I'm excited to see what other vintage electronics I can find and repair in the future.
