How Long Should a First Watt SIT3 Last ?

@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.

Hi Tony. I don't know if you're still undecided as to whom to let service your Quickies but the first guy I'd call lives and has his business in MSPL. Give Ralph @ Atma-sphere a call. He can and has worked on all kinds of tube amps, regardless of design philosophy or brand and I have no doubt that he could service yours.

I got my Quicksilvers back today, listening to Diet ILg presently old friend.

Jeff  said the problem was that the old style way to bias the tubes in these with the LEDs had failed. He added some multimeter plugs to set the bias. All sounding great and for those using PSAudio, I went back to Windom today.

All told, the bill came to barely $200.

Happy Camper.

Thanks all,

TD

@mrdecibel Looking back concerning baffling the horns in the Heresy IV, yes I did in fact try that but was not happy. The harshness all went away I believe in the 7th week of constant on.

I did stuff the port holes with acoustic foam. with the ports open the cabinets were singing and it was not appreciated. Foam still in.

Thanks for everything

TD

Good to hear! Have a happy 4th:-)
