TC VoiceLive 2 or Eventide H3000 for vocal?

Surprised they didn't ask for a hole to be dug for a hand crank too to make the chip upgrade more convoluted. |

They sell to all the folks doing repair work in the state (and actually in a lot of the central Pacific). They are the place to go when you need a 6DJ8 tube or a soldering iron. Check with the ohmmeter and see. Are we talking continuity check between the pads that should not be connect= ed per the upgrade instructions? And continuity check between the pads that ARE supposed to be connected. You could have a solder bridge, then again you could have a cold joint. The ohmmeter will tell you for sure.

Now everything related to that is going to have to come off the board, the lifted bit replaced with a piece of hookup wire, and the whole thing put back together. It has just gone from a relatively easy job with proper tools to a much more time-consuming and difficult job. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

The "lifted" pad that I soldered seems to conduct current quite fine, even if it looks uglyish. (Second soldering from left) Basically everything checked out except the nicest looking first solder. Huh? I gently removed the soldering, checked the two bare pads themselves - no continuity! No wonder then! http://www.southseascave.com/wp-cont.../cont_test.jpg These two were unconnected in the original setup. So I tested the two other pads of that triplet which used to be connected. Also no continuity! I did blow something, then, perhaps the nearest soldering to the left of those pads. I noticed how it kept getting darker as the work dragged on; it wasn't too glossy to start with. Do I call Precision Radio? |

I dropped off the H3000 at the repair shop recommended by Precision Radio. I gave them a copy of the service (repair) manual and the 5-page upgrade instructions which says nothing about the solder resist booby trap.
They'll let me know if they can do something with the unit. I notice there is a tropical fish store nearby. |

I got the H3000 back from the recommended repair facility. The two pads that did not have continuity are soldered. The soldering itself has continuity. Rom chip #1 is reinserted flush wrong in the socket. The power unit was upside down Total cost $20.
The H3000 does not start whatsoever. As in, dead like George Washington's grandmother, even the screen doesn't blink when I flip the switch. The fuse is OK, voltage is still at 115, yet it's bricker then when it went in. |

I removed the solder that the fellow put on the pads, and underneath, the two pads still don't have any continuity. As when I left the unit with him. (Except then the LCD worked.)
So the fellow did not trace the line why there's no continuity, apparently. He slapped a gob of solder on the pads, put the chip back wrong and charged a twenty. And that's "the" recommended place... :-) |

I removed all the upgrade solderings, resoldered the single pre-upgrade link, replugged the Rom original chips and et voila - functional plain H3000 again!
http://www.southseascave.com/wp-cont...00_is_back.jpg One thing is different, though. The machine only has programs 105, 106, 107, 109, 110 and 253. I powered the H3000 off and replaced its original second Rom chip which the upgrade set's. Will I get a kajillion programs now? Restart, reset... nope, still only 105, 106, 107, 109, 110 and 253. These presets must be on the first, OS Rom. And yes, when I powered up with just the OS Rom, these 6 presets were still available. So the second chip isn't "coming in". Powering up with just the upgrade OS Rom produced no love, so I put the old OS Rom back. (To think all this heap of trouble is because Eventide designed the Rom area of a $3000 unit in a way to require soldering just to accommodate more Rom chips...) |

I'll point out that my bench fee just to look at something like this is around ten times what you paid, so I'd say you did well. Take it back to him, explain what happened and what you measured. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

I figured out why the second chip did not "come in". It's the pad I severed per the upgrade instructions. (Yep, the "lifted" one.) I soldered it back to the adjacent pad to which the severed line used to go, and pronto - all the presets are back and everything works as before.
And that's when I put this H3000 back up on eBay where it came from pronto, and call it a K.O. win for the TC VoiceLive 2. A H3000 can't MIDI pitch shift polyphonically, done deal. Question settled. |

Thanks for all of your hard work to get that answer. You are welcome. The apparent fact that no one pursued this question since 1988 makes me wonder if the Ultra-Harmonizers' main use in studios was not harmonizing at all? Even Eventide's Wikipedia page only highlights snare and solo vocal pitch shifting, time-compressing movies, flanging, etc. It doesn't mention creating harmony from a vocal anywhere. I guess "Super-Shifter" just wasn't impressive enough for Marketing? |
