What are some of the better tuners out there?

"I find myself needing to replace my tubes every 4 months or so and I don’t use my tuner that much."

Clearly that's not normal. You weren't doing that when it was new.

As mentioned in my original post-tuner tubes are  not driven hard. They can last decades. Either you're using inferior tubes or it's an issue with the tuner. 

audioguy85 mentions the Cambridge Audio 500T. I have the 550T as a backup. They are not the caliber you're looking for, but good functional inexpensive SS tuners.

Seek out a Pioneer Elite F-93.  It slayed the Day-Sequerra and the Naim Tuner in its Stereopile review.  The only reason it wasn't given the five star treatment was that it was Pacific Rim sourced and at that time and in that place, Pacific Rim Tuners weren't allowed to be "Five Stars" in their pages.  If you read between the lines it's easy to see what's since become completely transparent "damning with faint praise" because (the old, '90s Pioneer Elite) wasn't funding their advertising revenue gravy train.

That is the biggest pile of BS I have heard here to date.

there was a log running tuner shootout on the internet.  you can find it by google.  they matched one tuner against the current champion.  had about 75 when i quit reading.  i think  a sansuii was on top.  i had a sansuii tu9900.  it was very good at tuning in stations.  most fun to listen to was a Scott 340b.  but it had constant alignment problems.

"Pioneer Elite F-93. It slayed the Day-Sequerra"
Well...it is subjective audiophoolery  right?

I'm gonna find that article. Sounds like a good read.

A $50 used Pioneer FM tuner that was made to match the rest of "the rack" in the $700 package at the Good Guys. "Slays" the DS?

I'm giving my  65 Mac away for the Pioneer.
