I used sync for reddit for years, I had no ads in the free version and the pro version. I’ve tried a half dozen apps for Lemmy since my Reddexit. Sync for Lemmy is far and away the best. I really missed its design. I was happy to toss $20 to you for no ads on Sync for Lemmy. Thanks for all the hard work.
You must not be familiar with North American power systems. I would bet the op had single phase service providing 220 or 240 volt service. 60 amp service is outdated, 100 amp is basically the minimum and 200 amp is common.
