can't answer your question but it seems by now that the effected change is probably permanent. Hope that you saved the old diode for reinstallation.

It's very possible that 100 hours is not enough for your new Capacitor. Cap changes are extremely audible in both amps and speakers, especially when compared to the old part that may have thousands of hours on it.
On the other hand, after swapping Hexfreds in an Atmasphere amp, I had no change in tonal balance or brightness.
I would remain patient, it takes the same amount of effort to swap parts later as now and the issue may resolve itself with more music.
