KT 170

I haven't tried the KT 150's yet, now this-

" With the success of the KT120 and KT150 they dialed things up yet again with the KT170 which has a plate dissipation of a whopping 85 watts! A pair of these badboys can put out 300 watts." That's a lot of juice!


Price isn't too shocking, comparing it to the KT 150.

PL owners, Buy them and report back.

Here's tube dimensions

I'm looking forward to reading user impressions of this big tube.
Perhaps the KT150 turned up a notch in all areas?

I'm super happy with my Ayon KT150 amp.  15 months on same power tubes and I haven't noticed any degradation.  

But it's tantalizing to think about trying this new 170.  Doesn't look much more expensive than the 150!

Interesting, but would any current amps be able to work properly with a KT170?  Simply plugging in a bigger tube doesn’t mean more power.  Most amps can’t maximize a KT120 let alone a KT150’s unless they were designed with those tubes in mind.

I wonder how many people stick with KT88 (or 6550 or EL34) for the sound over these higher power variants.

It’s for it’s hard for me to imagine the KT170 will be any kind of improvement over the KT150, which sounds perfect to my ears and for my needs
