Looking for entry level EL34 tube amp

Hi everyone. I am looking for a entry level EL34 tube amp and fell over this on aliexpress.

It would be easy to replace most of the passive parts with higher quality parts, but i assume that i am pretty screwed when it comes to the transformers. Go, or no go? Budget is ~300$.
 
Good or bad, I can not tell.
One thing is to be sure it is wired for your local power.
100V, 120V, 220V 240V. Do you have 50Hz, a 60Hz transformer will get hot.
Most similar amps on the web want you to state your power (it is expensive to have a power transformer that has all the primary taps).
 
Here is an example.

You need just an output stage that is pretty simple.

Buying a cheap amp, then 'upgrading' all the things which do not matter very much (i.e. most components) but leaving in place the components which make the most difference (transformers - which will be poor in a cheap amp) is a good way to waste money. Better to find a good design, buy the best transformers you can afford, then use perfectly ordinary components for everything else.

Perhaps i should try to find a kit somewhere with a PCB and potentially BOM, then buy the transformers locally in Europe. Is there such thing?
