Hi. I have a Mark IIB combo that I just bought. The clean sound is pretty good although I think it could have more bottom end. But I can't seem to get a good lead sound out of it. Not the singing overdriven sustain of CArlos. It's just crunch, but not good crunch if you turn it up.or else weak. I think there must be something wrong with it. I was thinking of trying to send it to the Boogie factory to have them go over it. Do they do that? I thought I heard of a factory upgrade to IIC+. Anybody know anything about that? Also, I took it apart and most of the caps are orange drops. Is that stock for a IIB or have they been replaced? I did try different power tubes but no help.
Thanks for any help with this. I love the Boogie sound and want to get it sounding right. I also noticed that the traces of part of the circuit board were dull and had a silvery powdery coating. Is this bad?
I also have a Mark I with problems. When you turn it up past 4 it starts oscillating, like feedback kind of. What causes this oscillation? I tried different power tubes but it didn't help. It also has very low power and bad sound quality with a 60 cycle hum. The caps are Mallory except for the filter caps with have a pale yellow can. Are these stock?
Any help with this would be greatly appreciated. Any techs out there?
Thanks, Paul.
