Hi guys!
just for fun and in order to learn (I'm still a newbie!
) I would buy this vintage amp module kit (please see the picture below)
It's very...very cheap, because is a new old stock.
Is it easy to assemble, in your opinion?...the things that worry me mostly are the two trimmers on the circuit board: i mean their setting.It's the first time for me, but I love so much this vintage DIY amp kit!
What do you think?...Do I give it a chance?
Please guys give me your opinion!
Thank you very much
Regards

It is a simple, discrete stereo amplifier with a single potentiometer (per channel) for adjustment (probably bias current or offset voltage). It should be fairly easy to assemble but you need a multimeter to do the adjustment (with the potentiometer).
If it is that cheap, give it a chance. DIY involves running a small risk that the project will fail, but we learn all the time.
Have fun.

NB: This is simplest and cheapest kit I have ever assembled

It worked well, needed no adjustments but I had to add a small aluminum plate at the rear of the TDA7297 chip for cooling.

The MoFo would be a good option as well. There's a whole thread about it in the Pass subsection.
The kit shown in Post #1 should work well enough, though. I wouldn't expect HiFi quality, but rather a good learning experience. As suggested above, the electrolytic caps may have dried out and should probably be replaced. Then again, they might not have.
One of the many LM3886-based amps could provide the same learning experience and possibly better sound too. It'll be less plug-n-play in most cases, though.

The instructions should tell you what power supply you need.
Or download chip datasheet to find out max voltages.
I'd guess from looking at the pcb that's it's a single supply circuit.
Good luck, post here how it turns out.
