Bad-ish LM-2S?
CPRail:
Speakers were single, no double hook up. I use Scale Sound System speakers - they are rated at 1W, 8 ohm.
KPack:
On the dozens of modules I've installed, I had a single one with a bad amp. It was working fine, then out of the blue the sound spiked and cut out. Motor movement ceased. When powered, the module got extremely hot right next to the 6 pin plug (LM-2S) where the amp is located. Sent it into Ring and it appears that a small piece of stray solder from assembly had come loose and shorted the amp. The module was replaced.
Your situation sounds similar to what I had, minus the blown speakers. My speakers were fine. Shoot Ring an email or call them and see what they suggest.

Alan:
May want to check if the speakers are really "blown". It may be a case of them getting hot because the LM was feeding them DC. The LM doesn't have enough wattage to blow them in the conventional way - over extension of the coil. They may be okay.
CPRail:
Good to know. Thanks Alan.
They sure smell bad, even unplugged, but I'll give them a test.
CPRail:
Continuing the saga, I just checked the speaker leads on the suspect LM-2S– it’s putting out 4.8V. A new LM-3S that I also tested is putting out 0.12V for the speaker. Something is definitely fishy in Camp Wiganishee!!
Also, the LM-2S is still getting warm, even without the speaker plug.
Open it or send it to Ring?
Oh yeah, Happy New Year!!
