vintage AWA-F240 awa240 distortion and noise meter repair
« on: August 04, 2018, 09:25:24 am »
I recently posted a question in the forum (unfortunately nobody answered yet!)
https://www.eevblog.com/forum/beginners/measuring-thd-with-vintage-awa-f240-distortionnoise-meter/
anyways later when I looked at the photos, I realized the meter red texts and lines, faded off, probably because of the age of unit and UV. I decided to restore the meter face and I thought just post the images and results maybe someone interested to see inside this old unit.
interestingly they used a piece of un-etched fiberglass PCB for the meter face!
