Hello -
My Roadster head has static on channel two, much like a bad tube or dirty socket. I have already replaced preamp, power, and rectifier tubes, and cleaned sockets.
I've narrowed the presence of symptoms down to being heard only when low, mid, and high controls are turned up on channel 2. When those are turned all the way down, the problem disappears, even if I have gain, master, and presence all the way up. The static sound is unique to channel 2, which initially prompted me to change the preamp tube. The problem is worse on Brit and Fat modes. I see that Channels 1 and 2 use V2A for gain stages, but I haven't noticed the problem in channel one across any of its modes.
Any input would be appreciated. I've looked through the forum before posting and haven't found a topic that was specific to this issue. Thank you in advance.
