Erm.. Bicycle Sound Systems!?
You mean like Granppa's six or eight speaker setup on his Hog .. Cranked up to 110dbs.
So pedestrians 2 blocks away can share his Fave Johnny Cash tunes ?
Cuz he's riding a mufflerless Harley (loud Pipes save lives you know 🙄 And he's deaf to boot.
Nano tunes stick and ear buds not enough to impress the pedestrians?
Lepai t 2020 thing is Laughable. Many are DOA and the rest produce mediocre sounds .. Even.. when modded to the nines.
IMO $20 delivered is wayyy too much for what you get..
But Hey! buy a few more and you too may have an Epiphany as well.
G'luck

I may just go ahead and snatch up another one for home use.
Even with the one channel working and both lines hooked to it, it still gets the job done.
I have bought over 200 sets of Lepai LP-2020A+ and so far (touch wood) only one set had problem. It isn't a serious problem either, just one of the LEDs blew. This is less than 1% DOA rate (that is if you consider a faulty LED DOA).

Hi all,
I just got the Lepai and would like to ask if its ok to replace the output caps with E caps instead of Film.

An externally hosted image should be here but it was not working when we last tested it.
Thanks...Ok I see why everyone replace the original with film caps. The PCB doesn't label the polarity.
I found the first thing to do was put more PS filter caps across the line of the power supply link between the PS and the amp. Not changes, additions. YMMV 🙂
sound cuts out
What can I do to stop my lepai 2020+ from cutting out when I turned the volume up. I have it installed on my bike so I need it loud to hear it over the pipes. Is it something I can take off to get rid of the protection circuit.

The caps have no polarity in the output stage since the signal is in AC. Use 0.22μF Caps for 8 Ohm loads and 0.47μF Caps for 4 Ohm loads.
It's also a good idea to re-locate the Differential Output Capacitor to the speaker terminals or even inside the speakers itself to get maximum noise filtering.
Hello, I am considering one of these amps and a pair of Dayton B652 to get my feet wet in this world I've discovered.
PE sells this amp with or without a 12V 2A power supply. Somewhere I read that a 12V 5A power supply would provide better performance.
First, is this true? How would a higher current rating power supply affect performance?
Second, a quick search for a 12V 5A power supply yielded many many choices with differing price tags and shipping options (some free). What would be the ballpark price on one of these power supplies that remind me of a laptop power supply?
Thanks

A higher current power supply definitely helps improve the performance of the Lepai amp. It is more stable and it doesn't "shut off" halfway like those lower ampere power supplies do.
There are tons of AC power supplies in the market. A high quality power supply should look sturdy and solid. It should meets and complies to all international safety standards and regulations. The cables should be thick and are safety rated. A ferrite ring at the equipment end is another sign of good quality. The power supply should feel "heavy" in your hands.
Also, choose from a reputable OEM manufacturer such as Lite-On, Delta and Li Shin, etc.
By the way, do take note that the dimension of the jack is 5.5mm X 2.1mm.

If you find the 12V/5A power supply, please post any details here, so that others of us can source them.
Thanks.
Yes. The SQ improvement over the "bundled" 2A PSU would have to be earth shattering to justify a $33 power supply for a $25 amp.☺
The Toshiba type (clone) Laptop 12 v 5 amp units on Ebay are usually ~10$ delivered and work "fine'.
2A isn't enough power, there IS audible difference
Most certainly will Outlive the Ta 2020 'amp'

I am using a 12V 5A Sanyo AC adapter (Made in China using Japanese components including Nippon Chemicon and Rubycon caps). Costs around US$15. Very stable.

Here's an ebay listing for a 12v 5a psu with the proper barrel plug: 12V 5A 5 5mm 2 5mm 2 1mm AC DC Power Supply Adapter Lots Wholesale | eBay
Appears to be $10.00US each.
