Been 'reviewing' my latest version Lepai.
It is good, especially so considering it's 12 pack Beer pricings .
Likely even a bit better with new inductors etc .. I'm genuinely hoping :-).
'Wonderful' is perhaps stretching it a wee bit too far though.
Perfect gizmo for a secondary/tertiary system.
No interest whatsoever in what others hear or claim to.
Been doing this for wayyy too many years to give credence or even time to 'reviews'

I'm using something similar and it works very good but I am waiting on a 13.5V supply to test. As others on this topic recommend I'd say get a 13-13.5V one.

12V 5A LCD Replacement AC Adapter for DVE DSA-60W-12 1 | eBay
Although there was a problem with the supplied AC cable's plug (mfg error).
Fortunately everybody has a few spares

Did Several Mods today to my red PCB Lepai:
Good quality (yellow rectangle) output caps replacing the 047 blue ceramic output ones. Also a pair of 2.2 Film /foils replacing C20/21
Stock inductors .. still
ALL new better quality Caps, 4700/16v on PS as well as a bypass for it.
Have not yet touched the op amps or deleting the tone assemblies/circuits, wanting to get to know the thing modded Before deleting all that stuff.
Tone controls work, not impressively well, but they do work. Likely they will be removed.
Sound is good, Bass is decently deep and sharp when it's needs be :-).
No problems there.
Driving 8"full rangers . Volume is to genuine ear hurting levels and no clipping.
These are Old (early 70's) efficient and very pleasing drivers.. which is why I've hung onto to these things for 40 years :-).

Problem though. I tripped over the left speaker wire ripping it out of the cheesy lepai speaker clips. BUT now the thing is ONLY running on right channel. Left is Dead.. period
Have pulled off and refitted ALL the plug bits on the rear of the PCB.
Reflowed ALL the solder connections.. Still on right channel only. Grrr.
Shorting (finger tip) the 2020 chips' solder blobs on the underside of the board I can produce a large hum from either channel/speaker.
So Signal is seemingly going out.. I think?
I have a spare Ta 2020 chip,
But am thinking that the problem may not be the chip itself.. Any ideas?

Hi there,

Just make sure the Muse power supply is in fact 14V. Can't recall which seller I bought from, but the Muse power supply was actually only 12V even though it was advertised as 14V. My advice is to double check with the seller and also measure if if you end up purchasing.

Cheers,
Pete

The Muse power supply I received last week measured 14v.
Even it it only tested 12v it is still a very good buy, I would not have been too dissappointed.
I really do not notice the difference between my original 12v 2amp ps and the Muse 14v 4amp, but I am connected to some huge, efficient speakers

You mean you couldn't tell the difference between the Vonage power supply and the Muse?

Since Mean Well has been recommended as a power supply in general, I thought it would make a difference.
