Wondering how the reduction would compare, with and without the upgrade, to the Tetra Sans. I think the Tetra sans once I add the PS-1, transformer, chassis, tubes, it'll all be about the same price as the bottlehead reduction (without the integration upgrade).

I was also looking at the Bottlehead reduction So far, I've been looking at perhaps the Glass Ware Tetra Sans ( GlasssWare Phono PreampsĪlso, perhaps an ebay setup - Something like this EAR 834 clone Any specific recommendation that is a good starting spot for a beginner in this realm, will hopefully sound good and be worth keeping/upgrading down the road later would be most appreciated but I’m having trouble navigating it all to be honest. There are an overwhelming amount of schematics, forum threads, etc. I was considering one of the phono preamps on tubes4hifi (since that’s where I plan to get the ST-120 kit later) but have read some horror stories about the gentlemen who works with the folks the phono preamp side of the business regarding bad/issues with components and not being willing to work with people (not a good first kit for newbies). I am hoping to go with something that has “instructions” which are enough to help me learn the basics of tube building without being totally off the deep end. I have experience with a soldering iron, used to build wiring harnesses for car aftermarket engine ECUs, and took a class in college electronics basics ~20 years ago), but am not comfortable enough to be given a schematic and nothing else. I am hoping to find kit that is decent for a relative-beginner, which will allow me to get into the world of building with a reasonably minimal investment (<$200-400 if possible) and build my confidence enough to be able to work up to assembling a VTA ST-120.

Can anyone please recommend a DIY kit for a tube phono preamp? I have a Project carbon DC with the stock Ortofon 2M red, and am looking to “test the waters” with the world of tube amp building.
