comments: Hello Bendan, 
I have been using the Philips Miniwatt ECC85 tubes  
in my EAR 534 for a little over a week now. After  
replacing the current production 6AQ8 tubes with  
the Philips tubes, the EAR was just ever so much  
better. The EAR is no slouch when it comes to  
producing music that is emotionally charged but  
with the Philips tubes it became even more so. Even  
my wife noticed a difference, not an everyday  
"thing" so that is a testament to the Philips'  
benefit that speaks volumes! Well done! And as much  
as some NOS tubes can be a tad noisy in the input  
section of an amp, these are absolutely silent!  
Black passages are just that, and I appreciate the  
behavior of the Philips tubes in permitting that to  
occur! Bravo!
