I remember seeing something like 5-6 amps going back to be repaired.
Both Rolland and Bob said the mod "will work" but the amp won't last long running that hard.
First, let me start by stating that I am techno-stupid. I know little about capacitors and even less about resistors so please take my questions as though they are coming from a child...lol. Does that have something to do with the rail voltage? If so, the reduced voltage that Russ implemented might help. I know that he has done a hundred or more of these over the last few years and I have only heard one complaint, and that complaint just popped up on Rich's site once Russ and I were both gone. I know the two amps that Russ uses at his home were done 3 or 4 years ago at least and they are still performing perfectly. Hopefully, mine will continue to perform this was as well! Some of Rich's coming back could also be because of Rich's workmanship...which is not nearly on the level of some of the other people I have seen perform these upgrades. I don't think the concept is flawed as much as it is his implementation of the mods!
