How Long Should a First Watt SIT3 Last ?

Tony, do you have a backup amplifier to listen through in the meantime? I am glad you have the H IVs on stands, they are tighter and more open this way (my experience is the same with the series 1, 2 & 3). My tech is Kris Rhoades...Fine Tuned Audio in Orlando, Florida. Also, his partner, John Mintzer, in Tucson Arizona. They do great work, specializing in tubes. My best, MrD

Unless the transformers are bad, everything else is likely an easy and reasonable fix. I am not stating you should invest money and time into them, as that is up to you....However, I went the solid state route years ago, and have never looked back. My best, MrD.

Tony, you list on your system page that the Heresy pair are IV. Why I said IV. 👍

Wolf, hey...you also stated you heard very little to no difference, after you damped the horns as I had suggested. You are the only one of anybody and everybody I know who stated this. Just sayin. My best, MrD.

@tonydennison You can buy on the Bay a Sonance Sonamp 260, shipped, for under $100, all in. A very nice amp at the price and would be an excellent back up for your Heresys. You could have been listening to music through your system this entire time. Everyone should have a backup. My best, MrD.
