I now have a better way to enlarge the hole for the movement and will be posting a new video once I cut another one, but this video will still explain why and what needs to be done to install a new meter in your Hickok tube tester.
Please watch the video to see what it will take, and why, to install a new and improved American made meter from Hickok Meters. After you watch the video you can see if you want to do the install or have Hickok Meters do the install of a new meter.

The cost for Hickok Meters to do the install is the cost of the meter and $75.00 that includes us checking the calibration and making adjustments on your tube tester. Any additional parts or troubleshooting is extra. If you have and questions send me a message or email. zz@hickokmeters.com
