There were three version of this clock. The Serial Prefix on the bottom of the clock indicates the version.
Oldest "A" Version "N" Version "LX" Version Newest
Sometimes repairs where done and new electronics were installed but the serial number prefix was not changed on the bottom. Because of this you may want to download yours and the newer versions. All three versions set the time differently. The two oldest are large files. Sorry.

We repair the Kirsch-Hamilton clocks (sold by Hampton-Haddon)
A little Aurora history: About 40,000 Auroras were made over 20 years. The first were made by Rathcon and called the Spectrum (guess, less than 1,000 were made). Then came the regular Aurora that the vast majority of you owned. For the first few years Kirsch-Hamilton had them made and then the name (Kirsch-Hamilton) was sold to Hampton Haddon a marketing company. The Auroras were manufactured by Newton Plastics for Hampton Haddon (guess, 39,500 were made). Next, in the late 80's, Hampton Haddon had a version made in Japan that they imported (guess 1,000 were made). A lot of customers acquired the Japanese version when they sent in their original Aurora for repair and it was exchanged for the Japanese version by Hampton Haddon. Hampton Haddon abandoned the clock around 1991. Then in 1993 we at ChronoArt started manufacturing Luminas (a polarized light clock, see above) and then a year later started also manufacturing new Auroras and repairing the old ones.
The Rathcon versions of the Aurora (called Spectrum) can only be repaired by completely gutting the clock an putting in all new Aurora parts.
The Spectrum and original Aurora used an incandescent lamp that caused the clock to run very hot and shortened the life of the motor and the filters.
The Japanese version of the Auroras had the most beautiful colors and the nicest case; the aluminum was bright dipped and then clear anodized so it kept its shine and was hard to scratch. Sadly the Japanese clock motors had plastic gears that where easy to damage when setting the time, and those gears wore out much sooner than the metal geared motors made by Hansen that were in the original clocks. The Japanese version had the good idea, at the time, of using cool running, cold cathode fluorescent lamps, but they then made the mistake of putting these lamps too near the rear polarizer which damaged it and cause dark streaks on the rear filter, and then added to the problem by gluing in the rear polarizer, making it impossible to replace. Plus they used a motor with plastic gears that were not heavy duty enough to last. So like the Rathcon version once the motor goes the insides of the clocks must be completely replaced with the original U.S. version parts.
The regular Auroras, made by Newton Plastics, that most of you have were made out of polished, but not anodized aluminum. There is an advantage to the aluminum just being polished. If you scratch the case, the scratch can be polished out. With the Japanese version they were very hard to scratch but if scratched there is no way to fix a scratch.
For about the first 6 years that ChronoArt made the Auroras they were made out of brass that was nickel plated. These were the prettiest cases of all, but very expensive. Later because of cost and customers preferring the original case we went back to polished aluminum for new Auroras.
With Auroras the repair process goes like this:
Send in your clock with a note describing the problems (no need to call for permission, just send it). But of course it you have questions, call me (Barry Gamble). When we receive your clock we will send you several quotations, a minimal repair at minimum cost to get it functioning. Another quote to pretty up the filters, and a third quote to completely rebuild and update the clock to newest technology. A complete description of all the choices are included with the quote. Prices for Aurora are in one of the following areas (approximately):
$50 for minimal lighting trouble.
$129 to change the clock motor.
$245 for motor and filters.
$305-315 for the above and the new LED lighting technology.
These prices include shipping labor and parts. (Prices as of 6/15/11)
The Spectrum and the Japanese Auroras are $25-35 more.
With your quote in hand, call with questions, then you can choose the level of repair you want, and send a check or just give us your credit card information. Nothing is put on your credit card until the day we ship.
The average repair time is 3-1/2 weeks.
Warranty depends on the work done. When you have the compete ($300ish) job (75% of you do the complete job) with the LED lighting, then it runs cooler and is more reliable and we have less trouble so there is a one year warranty on parts and labor. If you leave the hot lamp inside (do not convert to LEDs) the warranty is 12 months on parts but 90 days on labor. If you just do a motor repair the warranty is one year on the motor and 90 days on labor. If you just do something simple with the lamp not lighting the warranty is 90 days on parts and labor. We only warranty the parts we worked on. For example if you just change the filters then there is no warranty on the clock motor.
Pack the Aurora with a couple of inches of bubble pack on all sides, use a sturdy box, and ship your clock to: Address
The Aurora base.
The Aurora original base had a plastic piece that covered the bottom so you did not see the wires inside. It was made out of a very thin black plastic that frequently has fallen apart over the years. It also had no feet on it so it could scratch the surface you sat the clock on. This was only a problem with customer with fine lacquered desks, counter, or bar tops, etc. Our new clocks have a much more substantial base of 1/4 inch thick acrylic with a routed flame polished edge and rubber feet giving the clock a more finished appearance. The base plugs are $9. We rarely include the base plug in the quotation, so if you want it, please call it to our attention. It is pictured below.
Aurora LED Light Conversion
The Problem: The original Aurora clock has had a design problem that most of you are very aware of -- it ran very hot. Most of the heat come from the incandescent lamp that lit it up. The heat discolors the expensive filters that create the wonderful colors and shortens the motors life. Every 12 years many of you have been sending in the clock for reconditioning. An expensive nuisance, plus it looked bad for the last few years.
The Solution: The Aurora can be modified to use the very long life, cool running LEDs. The modification costs $90 plus $10 in labor, when the clock is already here for other work.
The other advantages:
- More colors, both saturated and pastels. There is a microprocessor inside slowly changing which colors are being featured -- see photos below.
- Colors that do not repeat exactly twice per minute like the original clock. The action of the rotating quarter wave retarder (second hand disk) and the microprocessor are intentionally not synchronized giving you a much more interesting clock in the way it sequences through colors.
- A button inside that you can used to brighten the clock up for an office, or dim it down for a bedroom, or set it to minimum brightness for when you go on vacation.
- No lamps to change. After about 15 years it will get a little dimmer and after 20 years the motor will probably fail and you can send it in and have both changed.
For your reference 75% of the customers that send in the clocks for repair have the LED conversion installed.
Attention: Some of you are concerned about the LEDs making a change in how the colors are generated, thus affecting the purity of the design. 80% of the color changing is still from the filters; the LEDs just add another 20%. If the filters were not there then everything, the hour hand, minute hand, second hand disk would all be the same color. The LEDs are more of an enhancement to the polarizer technology, but certainly no replacement. It is still the polarized light technology that makes the Auroras wonderful.
Colors accentuated by microprocessor slowly changing what colors dominate.
Red, blue, green and white LEDs turned on. Eight LEDs of each color.

Prisma Service Information:
Give me a call. If the motor has stopped and you are a little mechanically adept I can probably just send you a motor and save you $55 in labor and $25 in shipping. A question I will ask when you call, "How hard is it to turn the setting knob?" Your answer will affect what we (you and I) choose to do.
If the lights keep going out, again, call me.
The Prisma's are easily damaged in shipping because they are so heavy. I recommend double boxing, with the front lens face down in the box. Insure the black case ones for $400 and the chrome case ones for $500.
The SPECTRA, or BLACK HOLE by Kirsch-Hamilton: We repair the lights only (not the motor which uses plastic gears, sorry). If the motor fails take a look at our Prisma II. It uses a metal geared motor and is a much nicer and more repairable clock for the future.
We have on occasion helped repair these clocks, but it is expensive. It is a much better investment to purchase one of the Big Binary clocks. It is a lot more fun and includes power backup.
The Sondex by Kirsch Hamilton has similar circuitry to our AUDOCRON and we can frequently fix these also. Just give me a call.
General Repair Information
To send clocks no return authorization is required, but a good note describing the problem is essential for good service results.
For the PRISMA, Model I, and AUDOCRON clocks phone before you send it. We may have some suggestions that will save you the trouble of sending it to us. Or, to save time, we can give you the choices and tell you how much money to send. Call :
