I' m building a Tubes 4 HiFi, SP-14, 6SN7 preamp. I purchased only the bare board and sourced all the components. I'm nearing the point where I will be able to test the assembly and compare some alternatives - like coax vs twisted pair, I have several tube sets availabe to try, and some outout cap alternatives that I can roll from other projects.
Anyway, I've got around $400 into it right now and I want ro see how good it is before investing more money into it. If it cannot, at this stage, out shine my Mac C-27, then now might be a good time to cut my losses.
One component worries me though. For testing, I purchased a 100k, Alps RF 2702 from Asia for $9.95 delivered. I would spend serious money on a good attenuator if the preamp warranted the investment. But I'm concerned that the little Alps pot might screw up to the test. (I even read somewhere thst the RH 2702 was a Chinese knock-off.)
Any thoughts on the Alps and possibly a better alternative for my purposes?
Thanks
