Kentiger HY-502S Amp

These are good amps for the size, function and cost – if you have a 3-5A, 12V PSU already?!

They can be improved by modding according to:

..agreed, those LEDs are annoying, better if they had been volume levels, not a disco..

Ok, you can buy a classic 90s used amp on Ebay for that £30+ total of PSU also, but if you want small, light (and free electric shocks!), but still good sound, this is worth it for the functions – USB and SD card for MP3; radio, remote control and about a 10W RMS output. Loud enough for most rooms.

I’ll do some tests…
