Your best value in tube gear are the offerings from VTA. The power amps are by Bob Latino and you very rarely see them on the used market because they're such a good deal.
ST-70 - 35 wpc kit with tubes $909
ST-120 - 60 wpc kit with tubes $1229 (this is a Mac 275 killer)
A used Mac 275 will run from $4000 - $8000,
They're not at all hard to build. I built very similar Dyna kits back in my college days. Get a soldering iron and watch a YouTube video on how to solder. I was soldering things at age 12. You can do it. Just take your time. Very good step-by-step instructions with everything you need.
If you can swing it, I'd go with the ST-120.
