If you are savvy in electronics and mechanics, it’s very easy to fix whatever components it needs and get it back to working. IMHO the 6F and 8F (8F maybe a tad better) are the best power feeds for the BP. I would never swap it out for something else. And never heard of anyone needing to replace a transformer in the 6F? If you can’t fix it? I would go the extra mile and pay someone to fix it, they are that good...Good Luck, Dave.
