Can’t you give it a rest? Your response is not even germane to the OP.
That’s funny because the OP actually weighed in:
I may get a kit from that fellow on youtube GR Research.
As to being germane, I think building and tinkering are very closely related.
But as for "giving it a rest" ... no. I find that we, stereophiles, are made better by having more builders and tinkerers. The entire concept of being an audiphile and stereophile was built by tinkerers and builders before there were buyers and sellers. I’m not here to sell a brand or tool but to encourage the visitors here to think about getting dirty with sawdust, solder and tools now and then. Our community is made better for it.
That can’t be bad, can it? 😀
