Crown & JBL Service

Certified Warranty, Non-Warranty & Legacy Repair Center

Crown Amplifiers and JBL Powered Speakers

At AE Techron, We Know the Importance of Quick, Reliable, Quality Service

KNOWLEDGE

AE Techron has been repairing Crown amplifiers, old and new, since 1999. From D75s to the latest I-Tech HD and Drive Core series amplifiers, our repair technicians have 70+ years of combined experience repairing Crown amplifiers and JBL Pro amplifier modules.

Our staff includes design engineers, many of whom were involved in the development of former Crown amplifier models. Should a repair prove especially complex, our service techs have on-site back-up via our in-house engineering team.

CAPABILITY

We are both a Factory Certified Repair Center and are a manufacturer of industrial amplifiers. This gives us the advantage of experienced factory Harman-trained service staff who are supplemented by Harman-trained and experienced assembly staff if you need a large number of amplifiers/speakers repaired or updated in a short time.

As an amplifier manufacturer, we have over $800K of parts in stock at our 20,000 sq. ft. facility, making it possible for most component level repairs to be completed quickly.

SCHEDULE YOUR REPAIR

LOCATION: We are centrally located in Elkhart, IN with next day UPS Ground service to much of the midwest.

COST EFFECTIVE: No surprises! Our bench rates and parts costs are similar to present Crown/JBL service rates.

You can reach our Repair Center by phone or email from 8 AM – 5 PM EST.

Thanks for all your help in getting this preamp to the service dept. as I was not on the list of your repairable items. There are a lot of memories associated with it and my son, who was involved when I originaly got it from a friend of his. Thank you and it will be cherished for along time with special thoughts every time I use it.

Jeff

Thanks for the attention you gave my old DC300A! I have been listening intently to it for hours controlled by an old Kenwood “BAsic C-1 Preamp” and am constantly amazed at how good the old beast makes my music sound.

These are my go-to guys when I’m searching for info and tech support on Crown products. When Harman took over Crown, The Elkhart, IN plant was forced to shut down and many of their techs migrated to AET. Their expertise with Crown products is bar none!

My thanks to those who did the fix on this unit. I appreciate that you took the time to test it out, (I purchased it used) give a thorough explanation, and that you have a sense of humor.

I want to thank  you for your work integrity. I really wanted to know the issue as I have another amp displaying the same symptoms. I will send any future equipment to your location and hope to get your input. Again thank you.

Ben

Awesome!  I am so happy I did my own searching and found you guys! And what an incredible story too! I had contacted Harmon Pro support and the individuals I chatted with were very nice and understanding, but they really weren’t able to help me. Every Crown Service center they connected me with were not as responsive. In fact, I heard back from one of the others today who basically told me that if my amp was intermitemnt working and then not working, that they really couldn’t do anything other than charge me to tell me that they really couldn’t do anything. Then i was told 14-16 weeks turnaround … argh … us little guys are doomed.

But, back to you guys … Thank you for being there and thank you for your service!  I will definitely be keeping AE TECHRON on speed dial. Everything we use right now is Crown and JBL!  I really do appreciate you all.

Linear Amplifiers
Our linear amplifiers offer DC-1MHz with fast rise times and a very low noise floor. They are excellent at driving resistive loads and are used in for various applications in research, university labs, EMC, imaging, and magnetics.


Switch-mode Amplifiers
Our switch-mode amplifiers have the lowest noise floor on the market, while providing high bandwidth at a very low cost per watt. They are excellent at driving inductive and capacitive loads, reusing the returned power to increase apparent power as much as 4X greater than the rated power.


Gradient Amplifiers 
AE Techron is an industry pioneer in MRI. Our gradient amplifiers are high-power, DC-enabled linear amplifiers with an integrated power supply. They offer a wide bandwidth, very low noise, and exceptional control of drift and distortion.

Conversion Calculators
Formulas, equations, and calculation tools for most compliance engineering applications.


Ohm’s Law
Ohm's Law is valid for circuits that contain only resistive elements (no capacitors or inductors). Ohm's Law is true for voltage and current (DC) or (AC).


Effective Impedance
Effective Impedance is the DC resistance plus the additional apparent impedance caused by inductance and capacitance at a specified frequency.


Voltage to dB Converter
This function converts the linear relationship between two voltages or powers into decibels, and decibels in power or voltage gain or attenuation.


Voltage Dropped & Power Dissipated Across a Series Resistor
Power dissipation is a measure of how much power is converted into heat in a circuit due to inefficiencies.


Compliance Voltage
Compliance voltage represents the maximum voltage a current source will reach as it attempts to produce the desired current at the desired rate of change.


Decibel Conversion
Converts between decibels, voltage (or current) gain, and power gain.


Watts to Joules Conversion
Convert watts to joules by entering the power in watts and time in seconds using this easy calculator.
