Darn I was thinking of using it for my hydrophone project

Maybe but it is also much easy to work with (acrylic is brittle), totally heat proof when soldering, helps to maintain things clean of flux, and the most important a much better dielectric.
edit : Can i use / modify a chinese tube mic power supply with pattern switch for this project or am i forced to build Poctop's PSU ?

Of course you can. This is a DIY site. Nobody FORCES anybody here (at least I hope). And I have done it (modding PSU).

You can either use a smaller Chineese PSU at 120V. I ordered one just this morning. Add pattern switch, easy.

Or modify one of Thomann’s - T.bone power supplies. You will need to lower voltage (two parts to change) maybe filter better the output voltage & ground it better. Fellow GDIY members went on at length on how to achieve that.
