Tom Anderson Posted September 1, 2021 Share Posted September 1, 2021 I bought a single 1957 khorn 357 at an estate sale last week. Based on the paper work Ebonite finish w a gold and black sash. I think I need a very low watt amp to get the best sound but I have put a mcintosh m60 on it. The speaker hook up says 16 ohm. All the internet postings say use the 8 ohm tap. My m60 does have a 16 ohm tap. Is one preferred? W the m60s I always try to drive low end power out of more modern speakers. Here I feel like I should turn the gain and hum adjustments down on the amp? Any advice is greatly appreciated. It has been running great for about 10 to 12 hours and then jumps into a thundering hum. My friends at audio classics says that sounds more like a 5u4 tube?
