I mentioned the sound of the KT-150 tubes in my review of the Raven Silhouette Reference amps. You can read my Raven Audio review here:
Raven Audio Silhouette Preamp and Amp
Unless Bob has a switch that can toggle plate/grid voltages the KT88's will probably not be able to be used. My Octave V110 has a switch on the back that changes the plate/grid voltages to be used for EL34/6550/KT88/KT90 (70W) or KT120's (110W). Turns out my Ei KT90's works fine in the high voltage circuit. I wrote the owner/designer of Octave (Andreas Hoffman) asking about the KT150 for my V110 and said they will work just fine but will only be able to hear the sonic differences between the KT120 and KT150. NO power increase. He said he is considering a new amp to take full advantage of the higher power the KT150's are capable of.It it sounds like you were quite happy with the kt-150 in your review. In the review you mentioned that with these tubes nothing stood out across the spectrum I take that as a good thing. In your opinion will these be the new standard for power tubes? When I sent my amps to bob he requested that I send the kt-88's with them so I am not sure if I am getting them back or if he will keep them and just send the 150's. I'm hope I will get them so I can compare the two tubes.
Got a message from bob this morning saying my amps were completed. He wanted to know how I wanted them signed. Do I have him personalize them to me or just sign his name only. I feel the personalization hurts the value. What do you think?
His name only.
and oh yea my sister signed it too. that really hurt the value.lol.
I could not stop laughing when i read this lol cute
