Where do the tubes go?

Relax and don't be stupid (get a reasonably powered amp with outputs at 8 and 4 ohms, plug it in, enjoy). Regarding reliability, there are FAR more tube guitar amps than hifi amps out there and they're often mercilessly dragged around, including combo amps with the speakers in the same physical space as the amp, tubes mounted upside down so all the heat goes up into the chassis (nearly every Fender amp ever made), and being used by people who don't care about the amp's inner workings as long as it powers up and doesn't quit in the middle of Louie Louie (more important than your listening room, how many tube amps quit at concerts with 15,000 plus people? Nearly zero...for years and years). Very similar circuits as hifi amps in most cases, but hifi gets the "precious/cautious" baggage attached. I recently had a new "Boutique" Class A hand wired all tube guitar head dropped by UPS so hard it bent the entire corner of the amp (heavy "lunchbox" style steel case) and after getting the kinks sorted with vice grips the amp works perfectly with no tube damage or any other damage. The myth of tube amp failure issues continues, and if you're too weak (disabled and extreme geezers excepted) to schlep a dead amp in for repairs or package it in the original box you should have kept, you're a wimp. Period.

There is descent tube equipment, and then there is spectacular tube equipment. The first thing to do is find a reputable dealer in your area and audition what they carry. I can tell you that there are two main types of Output Tubes - Triode and Pentode. About 80% of all dealers carry Pentode Amplifiers. Other than how the tube is designed - the difference is Triode Amplifiers typically output between 1.5 and 25 WPC whereas Pentode Amplifiers usually start at 40 WPC and can go up into the hundreds of WPC.

The difference in sound in my opinion is that Triodes sound best but due to their low output have less loudspeaker choice. Coming from solid-state it would probably be best for you to look at Pentode Amplification. Pentode can sound great. Just stick with Audio Research, Conrad Johnson, VTL, and the other big companies that have been doing it for a long time.

As far as going all tube equipment - it would be a win-win as long as you stick with companies again that know what they're doing. The music just sounds more natural and real. Of course, I cannot cover everything in a post, so first things first - go audition.

Revisiting this thread after a couple of days what jumps out at me is how passionate we tube lovers are about our music reproduction.Because tubed equipment "gets" the soul of the music IMO.Do the diehard ss folks gush like we do?Aceofhearts,go out and audition if possible and see if you feel it!Best of luck on your journey.

Studio 1,
You raise some good points for the OP as far as distinguishing in general pentode vs triode tube amplifier options. I like many who ventured from SS amplifiers to tube amps went the route of pentode initially, (triodes came later). These are predominantly push pull and often class AB configuration. This genre offers much flexibility in price, power and many brands and models and can provide very good sound quality when executed well.

Triode specifically directly heated triode (DHT) is another niche, examples are 300b, 2A3, 45, 211, 845 etc. These are used often as SET(class A by default) but also class A push pull. These amplifiers will as a rule have lower power output but offer a different sonic presentation that some will find very natural and life like. Both categories of tube amps have their admirers. Speaker selection is a critical aspect when considering a given amplifier.

Aceofhearts, I'd recommend that you do some reading on DHT and pentode tubes and certainly listening to these different types of tube amplifiers to help determine which type will please you the most.
