Also, not that this will help your current situation, but did you know that you can change the output terminals to match a 4-ohm load? The Cronus has only one set of speaker terminals, but there is an in-chassis swap (solderless, I'm pretty sure) to tap the speaker terminals for 4-ohm use. This may be a help for driving a "difficult load," which often means the speaker's impedance drops below 4 ohms.
rogue dronus magnum issues
I have purchased a rogue audio magnm that has played beautifully up till now, it's now dead. wont' even power up! I am going to contact Rogue. but I bought it second hand so I have no warranty. There is a potted squard section in the middle of the amp where 4 wires come in and are terminated. One of the 4 wires is burned insulation with exposed wires. I suspect this is the problem. How it happened I have no idea, I am running Martin Logan Aeris i's which are a difficult load but I would have assumed this would knock out the output tubes if abything? Help!!
