After 50+ years of listening to recorded music, I got a tube amp in February 2018. I had inherited a Thorens TT and some RB-5's and that was all it took.
I started doing homework on a tube amp. I ended up getting a VTA ST-120 kit (you can get them turnkey as well).
tubes4hifi.com is the seller. Bob Latino the kit builder has had a presence on the klipsch forum. Roy his partner designed the circuit over 30 years ago. It's based on the Dynaco ST70. The new versions have upgraded components. Bob is very responsive and generous with help before, during, and after. Roy is pretty helpful as well. They also have a forum with tons of info. After not doing any soldering for 25 years, the amp took me about 35-40 hours to build. I took my time and had no real issues- I was antsy and took a week before I plugged it in and turned it on. After doing so, I was bummed that I could've been listening to it. It sounds quite different to the Yamaha AVR it replaces. It's darker, faster, and more up front. Glad I did it!
Bias takes all of 3 minutes every couple of months with a multimeter and a flat blade screwdriver. Bob says not to make a huge deal of worrying about it either. I'm having autibias put on it now as I want to keep the tube cage secured (kids and other animals) but otherwise, I'd have left it alone. Tubes aren't a worry either as they're very available.
I will have it playing through a pair of Chorus 2's before the end of summer. Just have to pick them up...
I hope this doesn't sound too much like an ad. It's not meant to. The amp sounds great and it wasn't difficult to build (if you consider that route). I'm just a thrilled customer.
