Rogue Owners Unite

I have a Tempest MKI. Have been using Electro Hamonix tubes without problems for years. I bought a quad set of Gold Lions and they showed red plates after just a few minutes. Everything measures correctly per Rogue and I have checked every resistor around the tube sockets and they measure within tolerance. Cathode resistors are showing about 55 Volts droped across 660 Ohms for 83 milliamps. I tried adding resistance to the Cathode as high as 990 ohms without success. Any similar experiences? Rogue recommends I upgrade to the MKII. Anyone want to donate $1K?

Hello, did anytone who owns a HERA preamp buy longer cables adn have 3 of the shorther cables they dont need (or any length speare cables)?

Mines an Atlas..... almost a Magnum. Made by Mark special for Quad ESL57s. I'm so happy. Tried a dozen or so other amps. Nothing has even come close in my system.

Hello, does anyone find that the atlas magnum amp produces a hum through the speakers when paired with the kt120s? I just put these tubes in my titan atlas magnum and there is a hum through the speakers even with nothing else plugged in. I didn't notice it with the kt90s. I use a fairly cheap power strip with audioquest power and speaker cables and dynaudio excite x16s. When the preamp is also plugged in the hum does not fluctuate with volume control. Is this a ground loop or noise from the amp? Can it be quieted? Thanks.

It's probably a ground loop hum. I had something like that on the same amp (as well as many others) and a cheater plug (3 prong into 2 adapter on the AC cord) solved the issue. Try the amp first, then the preamp and so on.

Good luck.
