Was just trolling on the Upscale Audio website and noticed they are listing the KT-150 for $92 per tube. I also checked NewSensor's posted stats for the KT-120 and KT-150. The KT-120 filament draw ranges from 1.75 to 1.95 amps. In contrast, the KT-150 is reported to pull 2 amps. To my non-techie head, the extra draw is not significant. Nevertheless, I will not drop the KT-150s into my Ref 150 amp until ARC officially clears the tube. Hopefully Gary will have something to report shortly.
New KT150 tubes?
Has anyone any experience with these pretty new tubes. There are already one or 2 amps I know of, that use them. The review of one of these amps in a UK magazine suggested they were a little warmer and more natural sounding than the nearly new KT120's
The article also suggested they were a straight swap for KT120 based amps, with no adjustment necessary. They are more than twice the cost of KT120's, but still not too costly compared with NOS tubes. I know changing from KT88's or 90's to 120's. did require some amp modification. I have an ARC reference 75 and might want to try the new tubes at some point, ARC don't seem to have a customer E-mail service, to ask the question
