Budget Tube Amp (newbie)

Number one..resign yourself to a tube integrated (keep it simple) and be ensured complete compatibility vs going the amp-preamp experimentation route where negotiating the learning curve could become costly!
for your Advents I would pass on the Rogue ..why shoot a mouse with an elephant gun?
I suggest finding a clean used Line Magnetic  EL-34 based integrated and its in your budget.

Another Jolida recommendation. I just bought a Jolida SJ-302a a couple of weeks ago. It's integrated,  puts out 50 wpc, and was only $450 from my local dealer, who had taken it in from an estate sale. The drawbacks - it's not auto biased, but that's easy to do, it's about 25 years old, and it has no remote,  but it sounds wonderful,  and cost less than $500 including tax. I noticed a very obvious difference with my similar vintage Chapman t7 speakers moving to this amp from solid state.

Ok, in response to "bdp24", I appreciate you being brutally honest! So, yes, in some respects I DO want to see what all the fuss is about.  Having known a couple of friends who had the old Dynaco ST70's back in the day, along with the Macs, I was really impressed by the sound.  However, not having the funds to go that way, I went the way of SS amps: I've owned the old Scott, Marantz, Pioneer, and Yamaha. The CR 1020 is the current SS amp I currently own. I currently own a pair of Bose 601bookshlef (4 ohms), a pair of Large Advents (8 ohms), and a pair of Fisher STV-880 (8 ohms) floor standing speakers. All of which have been re-coned and, in the case of the Advents, the cross-overs and caps redone.  As some of you "old guys" may know, the older SS amps could run (2) sets of speakers at the same time. In that regard, the Fishers complement the Large Advents. (maybe, the other speakers I have will "play" better with a tube amp?) Thoughts??
That all being said, it still lacks the "warmth" of what I remember tubes bring into the picture.  So, thanks to so many of you who have offered your time and knowledge, I am attempting to learn "the way of the tubes". lol  Now, because of you all, I realize that the ST 70 is not the way to go for me as there are better models out there even in the "budget" realm.
So, for those of you who have "been there-done that", I welcome the comments.  bdp24 also mentioned that maybe a tube pre-amp might work with my current SS Yamaha??  Thoughts??
Now, I know I am going to probably open a big can of worms on the next subject. But, once again, I am totally ignorant about the subject:
" interconnects"  I've read where people are spending major $$ on them. "Back in the day", the only "interconnects" I knew about were RCA cables. So, now at 65, I don't think I need another SS amp.And, I'm willing to humble myself and learn. But, maybe "with a little help from my friends", I can explore this avenue without, (as clhs04 stated) " ensure complete compatibility vs going the amp-pre-amp experimentation route where negotiating the learning curve could become costly!"  Again, many thanks!
Best regards,
Rob

Don’t throw out the ST-70 idea just yet . I loved them as well in the 70’s when a couple of college friends had them and I didn’t. There are a number of good options mentioned above for both Tubes Amps and Tube Integrated. I decided on a used Ultra-valve and could not be happier . Frank Van Alstine is a gem to speak with as well . The idea of building one ( as easy as it sounds) or rebuilding an older one just didn’t appeal to me as unfortunately most of my electrical projects have ended up with a number of do-overs . I am sure I would have said the same positive comments if I bought the RM-10 or a Will Vincent model . All wonderful sounding AMPS that wont break the budget and can be worked on if there is a problem by any number of technicians. Parts are readily available. I also have a Rogue - solid state as an alternate that sounds completely different and I like it to.

 I rotate speakers that have all sounded very good with the ST-70 clone . Crites updated Klipsch Heresy 1’s, B&W 602 v3 and Sonus Faber Concerto’s . All reasonably priced and sound very different from one another . All bought second hand and most on AGON . Many great people here on the forum and a number with harsh opinions. 

As long as what you purchase is working properly and in good condition it will sound wonderful . Maybe you will head down the path many of us have with seeking constant upgrades. Some of which aren’t actually upgrades to our ears based on the system we put them in. 

Through experience I have found cables are a tough road and certainly can make a big difference. So does your power source. Make sure your vinyl is clean and your stylus is fresh . Sit back and enjoy the music.
