I would. I don't know the actual product but I've often bought stuff that 'sounds terrible' and been delighted with it. Even as a cab it would be cool. Stuff like sealant/glue around speakers should be easy to fix. Maybe some say 'sounds terrible' because its solid state.

In which case they may sound a bit like my diy tda2003 amp so probably not worth my buying one. Looking for something to feed my diy 1x12 cab. At rhe moment I'm using various pedals with my diy amps and happy with that for now. I also play a lapsteel BTW.

Just because they use a TDA2003 does not mean it will sound anything like your amp at all. By definition, chip amps do not color the sound. The "sound" of the amp is defined by the preamp.
OK fair enough. Havent seen them in shops to try out but planning to buy or build something for my 1x12 cab Sent from my SM-G935F using Tapatalk

Hey some nice blues riff there 
BTW, looks like you are driving a hifi type speaker box,, if so then be aware they are woofers and generally have a low SPL,, a real guitar speaker will give a much bigger sound,, louder per watt of input.
Phil.
A friend has a 12" guitar speaker I can use. Time for a bit of joinery I think

Finally did the joinery ( takes me a while to do stuff!) I now have the amp and some pedals powered by a single PS in a case and going in to the 1x12. Plenty loud for home use and a great platform for bigger amp builds. Speaker good for up tp 80w. 1w amp and pedals into 1x12 cab https://imgur.com/gallery/lKMg7CRSent from my SM-G935F using Tapatalk

Problem solved. I changed the mains adaptor supplying the pedal power supply. Noise now much at unacceptable level. Thanks again for your input. it stopped me going off om a fruitless and maybe expensive tangent! All for the price of four 9v batteries.  Sent from my SM-G935F using Tapatalk

If you are having noise issues with the amplifier, I would look into why.
The power pack itself may be the issue, noise wise.
I agree, most likely it is the power pack that is causing the noise. Sometimes this can be filtered by adding power caps inside the amp.
Thanks everyone. Power pack is not old but it was cheap so caveat emptor. I will look into using power filters though. Sent from my SM-G935F using Tapatalk

Ideally I want a wallwart with an earth connection if such a thing exists

OK let me clarify. In Ireland we have 240v AC mains with 3 pin plugs as used also in the UK. I am using a wallwart type power supply which has 3 prongs but the earth/ground pin is a plastic dummy, so the amp is not connected to 'earth'. My amp is simply a Kemo 40w audio power amp. There is slight hum which is OK, even with battery powered pedals but adding a pedal power supply gives unacceptable noise levels. The pedal supply works fine with a mains powered amp. When I connected the output negative to earth the noise went away ( using a mains plug). Is there another way to do this?

Take out your DMM and make sure what color wire is hot and neutral through the power cable. Then remove the cable and get a 3 prong type power cable. (Assuming you are in the US) Basically, you have answered the solution all ready in your post. Drill a hole in the chassis and attach a ground wire. It is really easy as you said in your post. Sometimes I find Black hot and other times white is hot...? Look at the function of the power cord in relation to your DMM. Adding a ground wire should solve your problem.
P.S. - Star grounding is something totally more advanced in my thinking in relation to just adding a simple ground wire.
I am using a power supply with no ground so that no mains voltage gets to my amp. Any suggestions on how to add a ground wire to cut noise? Sent from my SM-G935F using Tapatalk

Cool thanks. Cable not home made but may not have been intended for guitar. Jack on guitar comes out perpendicular to the top so I
prefer angled plug but works fine the other way. I was just about to open up pedals thinking thet were dead.

Yes the plug that won't work is TRS and it's the same with my other pedals. Explain?

I have a guitar cable with angled plug on one end and straight on the other. My Boss DS1 pedal will only work with the angled one in the pedal and the straight into the guitar. The cable works both ways when it goes directly from guitar to amp. Is that normal?
