Hi Dave,
No offence taken! You are right, that is precisely what I am trying to do. I realize that the only difference is the transformer. I know exactly how I am trying to get it to sound. I have had stereos in one incarnation or another for 38 years and never had a sibilance problem. Now I have one. There is some sort of peak in the upper midrange now where the sibilance lives. I have tried darkening things a bit with my stash of tubes but all I can do is make predictable changes in the tonal balance. The warm or dark tubes sound warm or darker, the bright tubes brighter, but no matter what there is sibilance. I have made sure the voltages are where they should be or were before. I have tried various filament voltages as an experiment, but can't tame the sibilance. Transformers are rather expensive so I would rather not change it out, but it looks like that is where I am headed. Rewinding the old one is not a bad suggestion, although it may have died because it could have been slightly undersized, who knows. Or maybe it's number was just up.... The current one doesn't even get warm. I was just thinking that a different coupling cap might do the trick for less money... You are right, the difference is the transformer and I am trying to compensate...cheers,
Don
