Is it near any modems or cordless phones or any other devices that broadcast a signal? I once had a preamp that was sensitive to a cordless phone even when it was not in active use.
LOUD popping Rogue Magnum
ugg! I left my lovely Rogue 99 Super Magnum pramp on for more than 17hours. It woke me up in the middle of the night with VERY LOUD banging noises. I thought we were having a home invasion! Fortunately my screaming who’s there? who’s there? did not wake my wife.
I had recently had the system made into a super at Rogue. When it was returned from them it sounded good. It now sounds incredible for 8-10 minutes. After the pre warms up there is popping on both channels. It’s very regular, pop.....pop....pop.. and very loud. This preamplifier has a separate power supply, as well as the internal phono pre. It makes this noise with any input source at all! It’s not static. It is extremely regular after the pre warms up. It gets much louder over a few minutes. My very good repair person in Denver ( Electric City Repair ) suggested tubes as the issue. I have 14 different tubes for 8 slots - I tried all of that. I think it’s a capacitor in the power supply. Changing those caps is not part of the super-magnum upgrade. Nor is changing caps in the Phono pre. I did not change the tubes in the Phono pre as the same issue occurs with the CD player, regardless. Can anybody help with this pop, pop, popping?
