Left Channel of New Torii MK IV went out...
11/22/13 at 01:54:19
 
Something unusual, not in a good way, happened about 40 minutes ago.  I noticed my left speaker had stopped working and went over to examine the Torii.  On the Left side the OC2, the OA3, and the Rectifier tubes weren't lit up.  The input tube and KT66's were still lit.  I turned off both sides and hooked up the speakers to my Taboo and continued my listening.  After forty minutes I turned the left side of the Torii on again with the same result. I thought I'd gotten off easy with just a rattling 5U4 rectifier but now this.  Sounds like a trip back to home base to see Steve. So what does this sound like guys?  Just a loose connection?  Mark.

Mark, the rectifier isn't firing up and that powers the other tubes that are not powering up.

The older of my Mk IIIs does this to me, I have to wiggle the rectifier about to get it to glow. Often once I do it works for weeks, sometimes only one session. I've cleaned the contacts, adjusted the "tines," etc. I even had the amp back and had it looked at and it came back the same way. Annoying. I hope that yours has the same problem because it means you can get it to work.

Lon,  earlier today I had put in NOS Rectifiers to fix the rattle in the right channel's stock rectifier.  So before turning on either side of the Torii just now, I switched the NOS Rectifiers to the other side making sure they were both well seated...with a little wiggle...hehe.  And just like you said, everything works again.  To celebrate I'm playing Jean Luc Ponty's first Atlantic LP..."Upon The Wings Of Music".  Thanks Lon.  A little wiggle was much better than sending my Baby to Steve.  Mark.  

PS...now if I could only find his "Imaginary Voyage" I'd have listened to all 4 of my favorite Ponty LPs.

Dear Mark ,

Glad to hear that your amp is working again. Smiley

Dear Lon,

Thanks for sharing that rectifier "wiggle" tip.

I bet the music from your delicious Mk3 makes you do the Boogie Woogie "wiggle" all the time! Wink

Regards,
LS

Mark, so glad that worked. Hopefully you won't have to deal with that as often as I do on that Mk III.

That Mk III is now in my second system and I miss it in the main system as it has years of seasoning on it and I bet it sounds at least 10 percent better than the new one as a result. The new one has a stepped attenuator and the bass controls, which are both great to have. . . but I have to use it for years for it to have the ease and depth in the quantities and qualities of the older one.

But it will get there.

Listening to some Monday Michiru on it and getting ready for the shower. Little bits of my life are good!
