As per tittle
Can someone identify this amplifier ?
Is up for sale in the big auction place but it looks very dodgy to me

Well according to the seller it's a Monoblock...Class A on top of that.
Just follow the link it has a few more pics
A diy Gainclone or similar perhaps although that would not be Class A. It has all the hallmarks of a diy job if you look closely.
I asked the seller and got this answer:
Hi,
yes they was built by a guy called tuck tong,A korean chap.Thats all i know about.
thanks.
Did anyone heard about this "chap" Tuck Tong ?

I do buy faulty amps and fix them but I was just puzzled with this one, the seller claiming them been Class A from Precision One where we can see clearly that they are a diy jobbie and to top it up the asking price.
Some people have very high dreams.
I can well understand the "rare" description. It looks like an ambitious DIY project but hamstrung by cheaping out on the heatsinks. Or perhaps Mr Tuck Tong simply didn't understand how much sink would be needed for a reasonable audio output level in class A, as adason says.
I'd say you're looking at what has been been a waste of money from the outset and the owner is trying to get his money back, with interest. The cases haven't been badly mauled and could be used for another project - perhaps a "JLH", "PLH" DOZ class A or similar if say, the side panels were replaced or covered with decent, full 2U size heatsinks. Then, the only likely content of value is in the aluminium cases and small transformers. The amplifier board is worth what a kit parts is worth to a DIY and the power supply/capacitor bank likewise. But what should anyone pay for the transformers, used cases and assembled boards, presumably without schematics, specs etc?? Well, certainly nowhere even near ₤350. I'd put a ceiling of ₤120 on the deal if I were desperate to have those particular amps but you know your own local market values and prices better than I.

100 VA class toroidal and a few capacitors.
Cabinet, heat sinks.
About 35-40 Pounds.
We get new working Mosfet amps for 50 quid.
This is taking a chance that everything works, and the transformer is the only expensive bit.
350 is silly money, you get much more than this botch up for that kind of money.

And "Class A" may only exist in the mind of the seller.
He just read the label applied to other amps and thought "cool, I´ll also say the same".
No idea what´s inside that case, STAY AWAY.

That mess has a dinky little power switch - a sign of poor sloppy design from someone who dosn't know crap.
Typical "backyard mechanic" amateur junk.

I can't see any amp section.
Only the transformer and a power supply, and a bit of aluminum channel.
And look at the mains wires on the switch!
I doubt they will even have the insulation class strength for mains wires, they look like bits of Cat 5 cable...
But I am not familiar with Class A amps.
This may work for a 2030 or so amp, if the supply matches.
Find something else to fix.
I wonder if the transformer is blown, and price offered should be for a second hand transformer, all else free.
Basically you are paying scrap value for taking away his junk.

And look at the wires coming off the rectifier!
Big as garden hoses!
Yet.... hair-thin wires on that power switch.
The seller must be a 12 year old that trolls the internet for things to do.
The power cable is soldered directly to the board, and thin traces bring that to the side where the power switch is wired. run !
I have a DIY Mini Aleph from the class A forum and the sinks are 300x100x40 and they get nice and hot for a 8 Watt Class A power amp the ones in the pictures from the don't stand a chance.
I think we had enough fun with this one and close this thread down but...
