Just bought a used Road King in an online auction. The serial number is 633. I have no idea about the history of the amp - if mods were made, last time retubed, etc. It was a trade-in to Guitar Center, and so they don't have any of this info.
I can get some decent tones out of the amp, but overall I am not extremely pleased. The worst problem is that when I use the "Purring Blues" setting on Channel 3, and bear down on a chord, it has this cracking/buzzing, busted speaker sound, even at low output, and even then overall sound is definitely not what I'd consider a "purr". My Peavy Classic 30 has a better tone. Also I have heard this same noise at higher output on Channels 1 and 2.
I have tried unplugging the footswitch, selecting different power tube pairs, loop in and out, and even diode vs. tube rectification, and the noise remains. So I figure that it is either a bad preamp tube, or something in the amp circuit itself.
Any suggestions for fixing the poor tone and noise other than trying a full retube?
Thanks!
