What are some of the better tuners out there?

You can stream any radio stations you like 

I have two Don Scott modified tuners..McIntosh MR-74 and Luxman L-110, both were great before the mods, and better after...

"I’ve found good results with Amperage tubes but I find tubes too inconvenient in that they burn out too quickly."

Tubes in a tuner can last decades. Why yours aren't lasting is the question. The Marantz 10B and quite rare REL are the benchmark. Saul Marantz modeled the 10B after the REL

Mcintosh MR78

I won't part with my   65 Mac  MR71 unless a 10B or REL fall from the sky into my living room.
Depending who you ask, a Modfierri tweaked MR 71 can go head to head with the 10B.

I have a  Magnum Dynalab Etude and an Onkyo Integra T9090 II.  Both are great, the Etude has a little more body. 

Yes, there are radio stations available on streaming.  While I'm a fan of high res streaming services like Qobuz, most radio station streams are very poor quality and don't come anywhere close to the sound quality of a good station played on a good tuner.

Solid State tuners- A Richard Modaferri modified MR78 is superb.I used to own a Magnum Dynalab MD105 and the '78 is clearly better. I also used to own an Onkyo 9090II. Solid reception, the audio was just OK.  Another solid state tuner I have is a Marantz Model 20- the successor to the 10B. Doesn't quote sound like the '78, but the '20 has its charms and an oscilloscope which is the best damned way to tuner in a tuner and adjust an antenna. In its day when tested (in 1969) it was said to be the solid state equivalent of the 10B. Other superior tuners can be had from Accuphase, Sansui and Kenwood. 

And I do concur that a properly modified MR71 goes toe to toe with a 10B. Unbelievably, over 20 years ago I passed up and opportunity to buy 2 10B's for $1200. For the pair.
