Archie,

This shouldn't happen. Did you check the size of the fuse?--should be 8 amp.  I have.a TV, a DVR, a universal player, a CSP2+ with 25th Mods and a Taboo Mk III connected to my ZLC. Has operated flawlessly and acted as if it isn't even jogging, for two weeks plus.

Sorry this has happened. Seems if the fuses are 8 or 10 amp a call in to Steve is the next step.

Does seem odd that a 5 amp would blow, but who knows. Hope he calls back and this gets resolved.

So far as I can tell you and I are the only ones mentioning having received the ZLC on the board. I'm enjoying mine. I had very high expectations and most were met. Rock solid, though the top cover does "ring" and I dampened it with a little brass elephant. . . . I don't like ringing case parts, seems it may be vibration prone.

I’m sorry you’re having trouble Adam. That kind of crap can be so aggravating! I’ve had mine going for a week or so with no issues. I hope by now you have talked to Steve and have figured out what happened.

Best,

Geno

Glad the mystery is solved; hope you get fuses ASAP and all goes well.

I'll be bummed if I have to change an outlet.  Besides being hard to do given its location, I swapped the Hospital grade outlets I had there for these thinking they'd give me better protection.  Could be a case of too much technology.  We shall see.

Glad it's all functioning. Don't know what to say about your meters . . . or my display info.

Hope it will act right for you this time, Archie.

Is it ok to leave it on all the time? Mine has been on non-stop since I got it about 12 days ago.

I leave mine on all the time. I believe it's designed to be perfectly fine with that.

I don't know if it's a transference of the weight and heft of the ZLC itself into my psyche or a real effect but the music I played last night had a weight and density at the base that was impressive.  It seemed to have a solid foundation that was somewhat lacking before.

I have a suggestion for Steve for the blanks above the ZLC switches.  How about labels either with or without lights behind them.  Six switches is beyond my ability to consistently remember what they correspond to.  My typical limit is two.  

I know!  I made labels too but they don't stick very well.  I wonder if we can find those inserts in white so a sharpie would show up.  I have mine in a cabinet so aesthetics aren't as important.

So far, so good.
I have everything on and use component switches, but I still wanted to know what was where, plus a couple things are on 24/7

I went the white paint route.  Since mine is in a cabinet penmanship didn't count.    

I like turning things on and off from a central location.  Reaching behind the ZP3 and CSP3 transformers was always a bit of a pain.

This is a really nice piece of equipment.  Anyone need a slightly used Trip-lite?  

Got my labels on. They stuck pretty well but I can see what Archie was talking about when he said he had trouble. If they fall off, I’ll go to the white paint pen.

Regarding ZMA bias...

When the line voltage drops, the ZMA bias also drops.  When the line voltage goes up, the ZMA bias will also go up.  

Regarding sound, the stored energy in such a huge transformer is going to pack a pretty serious punch compared to a wall outlet so amplifiers that actually consume some power are certainly going to sound better.

I put the 6P tubes back in my ZMA and have the bias set at 60mA.  The point I want to make is that now my output transformers are running barely more than warm.  Before the ZLC I could expect 120+ degrees.  If I had to guess, I'd say they are well below 110.

Certainly a welcome effect!  I think this must tie into the bias difference somehow as well.  Maybe we now have less heat and more music.  

Ahhh...
Funny...Had to have it
I like the round stickers

Geno needs another ZLC for his turntable. . .

Okay, I think my ZLC is well-broken-in by now. I began experimenting with incorporating it into my main system Tuesday and have continued into today.

I tried all the analog components plugged into the ZLC and all digital into the PS Audio P10. And then I tried the reverse, all analog into the P10 and all digital into the ZLC. My conclusion: the original option was the best, all components plugged into the P10. The difference was really not subtle--all components into the P10 exhibited noticeably more dynamic contrast and more "focus," with the best tonal balance.

Then I once again plugged the ZLC between the wall and the P10, so that the only item the ZLC was feeding was the P10 itself. Subtly I found this was the best configuration. There is a touch more mellowness to the overall sound, and a bit of a more controlled feel overall. I'm leaving this configuration in place. All power cords are the PS Audio PerfectWave AC-12 for all components. The ZLC is sitting atop the P10, which sits on a PS Audio PowerBase on the top shelf of my Mapleshade Audio Samson Rack Ver. 3. Like all my other components the P10 sits on VooDoo Cable Iso-Pod footers; as I don't yet have enough the ZLC sits on four Herbie's Audio Lab Iso-Cups with Green Moss Quartz balls.

Sound is very very good. The ZROCK2 is finally FINALLY broken in and sounding fantastic and that is what spurred this whole experimentation. I did this in waves as I found it takes about 12 or more hours after making the plug in and out changes before all the components are again at their best. . . . So the present configuration is only in place about ten hours but I can already tell it's my favorite and tomorrow morning it should "be all it can be" and I bet it knocks my socks off.

Over the last few years with my move back to the small powered amps, the "Z Amigos" of ZBIT, ZROCK2 and ZTPRE, and all the wonderful 25th Anniversary Mods the system has become a bean-stalk climbing beast. I love the "nature" of the sound.

One day I may have another ZLC to put back in that new headphone system. It sounds pretty okay without one so no real hurry. . . and that's good because I am very BROKE after all the changes I've shelled out for. . . .

Lon,
Great to hear things are coming together for you and things are settling in to sound great. Nice review.

Best,
Scott

And one final note: the ZLC continues to "seemingly" deliver about 5 more volts into the P10 than it shows entering into the ZLC on the gauge in the back.

Lon: Sounds like meters to me. One component of the other.

Given how differently my ZMA biases and the lower operating temperature of the transformers, I suspect something real is going on -- not just a meter inconsistency.  5V would be a big difference too.

My ZLC arrives Monday. I think I have small ground loop on my ZP3 because there’s an audible hum when my Torii’s Turned about half way. It’s not audible with music playing but I Think it could be quieter. We’ll see soon.

Are you sure it’s coming from the ZLC itself?  If you are certain that it is, I’d unplug everything and see if it hums with just the ZLC plugged into the wall. If it hums with nothing plugged in, contact Steve. If no hum, then plug in one component at a time until you figure out where the ground loop is. Good luck!
