How to re-cap Collins 75A-4 Ham tube receiver Deadly capacitor replacement
This video features installation of capacitors which can cause many performance issues. Also the main filter cap is replaced. If you own one of these fine receivers, I would highly recommend purchasing this all encompassing kit from Mark Olson, KE9PQ.com. Plan on about 4 hours for the complete task. There are a few micas that are a bit tricky to install. This kit will improve sensitivity, hum level and overall life of your radio. There are many improvements, service bulletins, etc, that I will cover in future videos.
