What are some of the better tuners out there?

If those tubes burn out to quickly there must be a problem with that tuner. Preamp tubes should last for years!

Small signal tubes like a 12AX7 or 6922 will work well on average for about 10,000 hours. If you leave your equipment on 24 hours a day, well you do the math: There are 8,760 hours in a year. So when does a tube go bad? It depends on how picky you are.
Here is a shootout on the best vintage FM tuners!

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.
