Anyone know if it is possible to mod the Mjolnir 2 to use a step attenuator for volume control?
Beyond my skill level, I don't know how you would do that with the chassis being as short as it is, nor how to get a PC mount attenuator converted to off board. Sorry!Anyone know if it is possible to mod the Mjolnir 2 to use a step attenuator for volume control?
Wow! I have never heard of that happening either. Is that outlet switched, by chance? Or one of the two sockets in it switched? Possible also that the two sockets are separated internally and fed by two different circuits. And if so, could be a loose wire on one of them which would explain the intermittent problem. ???Hi All!
The plot thickens! Was listening tonight, decided to play a little RDR2 with headphones on, left to eat dinner, and when I came back amp was off! Opened it up, fuse was good, stuck my meter in the nice, beefy power chord I have, measured less than 30 Volts!?! Started to plug in a different power chord, and thought "let me check the wall outlet the chord was plugged into". Now this is a duplex outlet, with one side powering my John Risch DIY power conditioner, with the DAC, the computer, and a few peripherals hooked up there, and the Mjolnir on the other side. Sure enough, the outlet the Mjolnir was hooked up to measured less than 30 volts. I have never heard of a common wired duplex outlet losing power to one side! Just nuts!!! And I never experienced this problem before I moved, my home outlet was long ago replaced with a Furutech GTX-D. Wow, don't see that everyday! Anyway, temp plugging everything into the Risch power conditioner, would replace the wall outlet, but this apt is temp until renovations are done, then I move back.
Back to listening, have a great night!!!
Edit: Come to think of it, I might replace with a hospital grade jack after all. If one side of the duplex failed, who knows if the other side might.
Did you just wake up from your hibernation?What's up degenerates how you all doing?
Hope you are feeling better and healthy. Glad to have you back.Been away from audio for health reasons and really easy to stay away from Headfi.

Another possibility it is, half the outlet it is operated with wall switch.I think both sides are switched together, but not individually. The other possibility is a painter painted over outlet, and a plug inserted on top of it pushed that paint inside. I’ve seen where you can use diag cutters to split a duplex, but they start out as joined by metal strips integral to the outlet. I’m no electrician, so I’m sure there’s plenty I haven’t seen, but still seems weird.
If you're showing 30v with the switch off, then the switch itself is likely bad or miswired. Are you measuuring the voltage between hot and neutral, or between hot and earth ground?And the winners are, Roman410 and Bcowan!
Yep, there's a wall switch that only powers half of the duplex outlet. The wierd thing is, with the switch off, it's showing approx. 30 volts. When I come into the room, I normally hit all 3 wall switches on the one plate. One wall outlet is totally switched, I have my floor lamp on it, didn't leave my iphone charger on it because it's switched. But I wasn't expecting this set-up. Since power to one side was always on, I just figured it was on the other. Those times without power (or at least some of them, I did have a bad power switch, metered it out to prove it), I probably only switched several instead of all on the wall plate (very dark room, have to have the fan/light on except for sleep. I have experienced switched wall plates before, but I have never seen half a duplex outlet done this way. Maybe that's why they make it splitable! Dooooh!!!
