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.

Interesting arrangement for the KT 170 to fit, Brad.

Must look quite dramatic with 2 amps in your setup. Bet it sounds great.

As an amplifier designer I can't wait to begin a new prototype. 

All who are upgrading make sure that you don't exceed your power transformer max current on the 6.3 volt buss. These tubes require 3+amps each.  The prospect of a build that will run 800 volts on the plates is awesome.  I will have to build matching transformers that can handle the 300 ma of current going to the b+supply. My current design is a little undersized for the 150s but in testing and a limited production has been reliable. This will be a game changer. I believe still that the best sounding amp I have designed has a pair of soveteck 6l6wxt+........ but we will soon see.

Hi everyone, just curious if anyone is running the KT170s and their impressions here in 2024.  I have been running them since March 2022 on my Black Ice F35 integrated amp, and I am happy with them.  I keep the KT150s as backup, though I never really compared the two. The KT150s came with my amp, and I immediately upgraded them to the KT170s as these had more "power". 

I also notice that Kevin's Upscale Audio still does not carry them...
