Location: The Great Pacific Northwest | I have been trying to do some research on the stack of Audient speakers I have. They are the 12", 15" and horns used in the Ovation combos and cabs.
Somewhere in the cobwebs I recall something about Ovation using re-branded University speakers, and never really thought about it. But did they re-brand them as Audient ? |

Location: Fitzwilliam, New Hampshire | As I read this earlier thread, I did find some info that put University Sound as the horn drivers and if they also used them for the Speakers or thru Audient branding that might make sense. I guess the question is are there re-cone kits available for those??? If CTS or some other brand how to identify the model number to search out repair kits is the next challenge!

Location: Boise, Idaho | Send a PM to Miles (Mr. Ovation). He had a lot of Ovation electric stuff, including speakers. There are a couple of Audients on ebay currently, but I don't think they are the 9702. I haven't opened up my K-6300 amp yet to see what lurks inside. One of these days I'll have some time. |

Location: Boise, Idaho | I couldn't resist, so I opened up the back of the K-6300 last night, after playing it a bit and noticing a fair amount of scratchiness in the controls. I was hoping a little cleaning would do it.
Rather than open the whole back, I just opened the electronic panel and found some surprises. The speaker (a 15 inch Audient 9725) appeared to be in good shape from what I could see and feel from the back. The wiring was another issue. One broken wire that someone had attempted to solder. It might explain why the tweeter volume control didn't seem to work. I tried to crimp that together, but failed. The two other wires from the back panel to the speaker had spade connectors in the middle that didn't look original. There were two dangling wires with male RCA plugs on the end. One was repaired and taped heavily. I don't know what those are for. I couldn't find any female connectors inside the cabinet. Two of the speaker wires were connected with little alligator clips. It looks like someone cut or broke all the wires connecting the speakers and then did a poor job of connecting them back up.
The worst news is when I put the panel back on after lightly cleaning the dust off, nothing worked. The light came on, but no sound out of either speaker. I took it apart again and couldn't find any loose wires, so I put it back together and set it aside for when I supposedly have a lot more time to spend tinkering. |

Location: Boise, Idaho | I forgot to mention that most of the labels for the input and output jacks are scratched off from years of use, but the warning not to open the back because there were "no user serviceable parts inside" was still very readable. Obviously, I and others during the 50 years of its existence ignored that label. |

Location: Fitzwilliam, New Hampshire | My K6100 cab was a disaster when I got it. Horn driver missing which made a perfect portal for the mice that was living in it for who knows how long. One speakers magnet separated from the frame the others coil wires chewed completely off and the power amp was totally caked in mouse crap! its been a slow process but I eventually got the cabinet cleaned (bleached) and a used power amp I found on E-Bay is on the way so speakers I'm and a horn driver away from putting it back together. The K-6002 head is another story. It actually works but some functions missing like reverb, tuner, and fuzz. I'm picking away at it a piece at a time. It'll be a nice amp once its all functioning and an addition to my tube amps although I'm not sure they'll take a liking to a "solid state" amp in the herd (lol)! Best of luck. BTW, are there any sources for wiring diagrams for these? I did find one site with some Ovation amp schematics at various prices. Hoping there's some being shared among the OFC. |

There should be a numerical manufacturers code on the rim or cone somewhere to indicate who made them. The CTS code is 137, Jensen is 220, Oxford is 465, etc.

Location: The Great Pacific Northwest | I will get out to the storage unit this week. We had some "issues" around here last week and I just ran out of hours.. I'd go out there now but the alarm will "bing bong" in the bedroom and wake Lisa... and sorry.. but no speaker is worth that risk  |

Location: Fitzwilliam, New Hampshire | I am also looking for a reverb module circuit diagram. After taking apart my K-6002 it appears as though a component (resistor most likely) is missing on the board. Reverb doesn't work but it seems a component was de-soldered from the board. The board number is a 6-0010-240 if that's of any benefit. Its also the last component on the bottom far left (connector end). I done some searching and there isn't much out there for these vintage giants. |

Location: Always beautiful canyon country of Utah | The art of soldering is something worth mastering. Never again will you be bothered with excessive resistance due to inadequately crimped joints. Crimping has no place in electricity anyway!! Plus watching the solder flow to the heated and properly cleaned and fluxed wires can be a religious experience secondary to none!! |

Location: The Great Pacific Northwest | Brrr... so I have six 12" speakers. 2 each of 9422, 9424 and 9442 Audient's. Not sure what the difference is. I have some horns and speakers in cabinets that aren't doing anything that I will need the weekend to get to. |

Location: Boise, Idaho | I happened to plug in the K-6300 this weekend and it worked! Don't know why I couldn't get any sound out of it last time. Sounds great! Scary loud. The controls on the back are kind of a pain and the horn doesn't work, but the big 15 inch speaker sounds fantastic. I'll fix the wiring for the horn when it comes up on my list of projects.
I haven't tried it with the VXT or any acoustics yet. I'm anxious to see whether it works as an acoustic amp. |

Location: Fitzwilliam, New Hampshire | No manufacturers codes on the ring. These are gray wrinkle painted frames and are either University/Altec or something similar. I've viewed many speakers from various manufacturers and these are a step up from the typical Oxford, CTS, Jensen, Utah, etc just in the materials and the craftsmanship that went into these speakers. Aluminum screw terminals for the speaker leads, etc. They are close to what I've seen in pictures of Altec Lansing and University Sound (now EV) from the early years. |

Location: Fitzwilliam, New Hampshire | I got the K-6002 head working all but the Reverb. The fuzz brings back memories (Rolling Stones - Satisfaction!!) and actually sounds pretty good with the blend controls to get different fuzz sounds. The G Tuner works marginally but not a big deal. Shot all the controls with tuner cleaner/lube and they perked right up. I Also cleaned all the input jacks with a brass 22LR rifle brush to clean out the oxidation and that fixed another issue. Ran the head into another power amp and so far so good! I have a couple of odd speakers kicking around I'll use until I get a good pair of Audients. |

Location: Boise, Idaho | You may have inspired me to open the K-6300 up again this weekend and fix the wiring to the horn and see if I can get it working. I couldn't get the reverb to work on it, either. |

Location: Fitzwilliam, New Hampshire | I noticed a component missing on the Reverb module and wondered if that was a failed component but without any wiring diagrams to go on its a crap shoot. However, if yours has the Reverb module intact maybe you can post a close up picture so I can identify the missing resistor, cap or whatever was in that spot? I'm assuming the Reverb module/card would be the same across models but again, I don't know but the card part numbers are usually on the PC board, so that might help. Appreciate it if you can.

Location: Fitzwilliam, New Hampshire | Another option is to test the reverb can in another amp. Mine seems to be ok, the springs etc intact and I cleaned up the RCA connections. Its hard to say what else can go wrong on those. Its pretty basic stuff except for the electronic modules. At least that might eliminate the can as a source of the problem. |

Location: Boise, Idaho | I assumed the reverb was electronic and didn't see any springs. Your mention of the RCA plugs got me thinking that someone may have taken out the reverb. As I mentioned in my 12/4 post above, I found two RCA connectors that weren't attached to anything and one had a bunch of electrical tape covering it. This might be more of a project than I have time to tackle next weekend. |
