ssh Posted June 17, 2018 Share Posted June 17, 2018 My JFL 2A3 monoblock's transformers have collected some rust. What's the best way to clean them? They are cobalt; I don't know whether or not that changes the recommended cleaning procedure. SSH Quote Link to comment Share on other sites More sharing options...
efzauner Posted June 28, 2018 Share Posted June 28, 2018 try posting some pictures.... or try searching the web https://www.vintage-radio.net/forum/showthread.php?t=140793 http://audiokarma.org/forums/index.php?threads/a-tube-amp-restoration-walk-through.655366/ you can remove the bell ends if they are really rusty and refinish them. As for the laminates, Seems a good approach would be cleaning off with wire brush or light abrasive scrubber . Then prime with one of those rust transformer products and then rust spray paint. I would advise against rust removers as they will get into the laminates and continue corroding the steel. https://www.theruststore.com/Rust-Converter-FAQs-W48.aspx Have fun!
