NOSValves Posted September 28, 2013 Share Posted September 28, 2013 One of the Joy's of being in the biz...manufacturers allow you to squeeze them for free tubes and other components for evaluation Too early to form an opinion just got a chance to get them hot... my NBS prototype preamp is on the bench for some tweaking so it maybe a few days before I comment about Sonics. Without it in my system my sonic evaluation would be flawed at this time. Electrically they seem to work fine. I really question the raised heater voltage specification since it does not cause a bit of voltage drop on my heater circuit. The KT-120 didn't either... The plate structure of this KT-150 tube is visually dead nuts identical to the KT-120 just taller and KT-120 plate structure is identical to the Tung-sol reissue 6550 just taller. I suppose the KT-200 will most likely be a bit taller than the KT-150.....and so on Cheers Craig Quote Link to comment Share on other sites More sharing options...

NOSValves Posted September 28, 2013 Author Share Posted September 28, 2013 Tex he has come a long way since you were here. He is super smart... I'm not all that sure I'm smart enough to keep him at bay LOL!! I already love the heck out of my little boy. That picture was about a month ago. Here is one I just took! He spent this evening over at a neighbors playing with 5 really large Labs! He had a ball and was very well behaved after the first few minutes, but those first few minutes were interesting as he tried to tear them (all 6 of them mind you) a new A-hole....this little sucker has NO FEAR.

jorjen Posted September 29, 2013 Share Posted September 29, 2013 Max is a keeper Craig! So is your Grandsons first name....[] What will you be biasing the KT-150's to? Man, they look sexy! Quote Link to comment Share on other sites More sharing options...
picky Posted September 29, 2013 Share Posted September 29, 2013 NOSValves: Kind regards to you, Craig! I haven't talked with you since you rebuilt my '61 EICO ST70, which is still kicking out the jams in our garage via the Heresey III's! I hope you and the Mrs. are both well and Max looks like a great little guy to have around! Take care my friend! -Glenn Quote Link to comment Share on other sites More sharing options...
paul79 Posted September 30, 2013 Share Posted September 30, 2013 Looks good! I'm liking those Mullard Box Plate tubes myself [] Jack russels are cool dogs for sure. Almost too smart, as you know. Good lookin dog. I think your dealer needs another opinion of these tubes.... Two people trying them out in the same amps would be the best way to review them, no?

NOSValves Posted October 1, 2013 Author Share Posted October 1, 2013 Jordan, Since firing them up I have had them biased to .80V which equals 80mA which in turn equals 40 watts of plate dissipation. That is about as hard as I can push them without stressing the $150 5AR4 rectifiers. So I'm going to pop in some SS rectifiers and pump it up to 100mA soon and then 120mA............ if they make to 120mA without melt down New Sensor has really done something. They sound really good as is.... I seriously doubt pushing them harder will net Sonic improvement but they were sent to me to evaluate the longevity at extreme punishment. Did you pump up the KT-120's like I suggested? What did you think? Quote Link to comment Share on other sites More sharing options...
NOSValves Posted October 1, 2013 Author Share Posted October 1, 2013 Glenn, It has been too long my friend! We are doing wonderful now living in the north country up near West Branch! The wife had a bout with Cancer this year and one the battle with a total knock out. It was expensive but the pain of the cost is way out weighed by the results! You and the Mrs. should take a fall color tour and come up and visit! Craig Quote Link to comment Share on other sites More sharing options...
NOSValves Posted October 1, 2013 Author Share Posted October 1, 2013 Paul, Yea Max gives me way more pleasure then the tubes! I'm glad to hear you are enjoying the Box plates! I'm not really performing a Sonic review they requested I put them through thermal melt down [] and report my findings. Craig Quote Link to comment Share on other sites More sharing options...

thebes Posted October 1, 2013 Share Posted October 1, 2013 I stayed away, I stayed away, I stayed away, but finally I've succumbed. Those tubes like silver suppositories , not that I ever had any occasion to use them. Max looks cute though. Of course, real men only hang out with dogs that meet minimum height. If it doesn't come up to your knee, throw it in the frying pan, it's not a dog, it's a snack. Quote Link to comment Share on other sites More sharing options...

NOSValves Posted October 1, 2013 Author Share Posted October 1, 2013 I just opened up a cruelty to animals case... Let me know where to report for testifying against this obvious cruel person. I can hardly wait to say.. "Sickum Max" when I finally get to meet Marty in person. Max is totally fearless and 100% dog. Quote Link to comment Share on other sites More sharing options...
muel Posted October 1, 2013 Share Posted October 1, 2013 I think Max is bigger than his size. His attitude must make up for any lack of stature. Quote Link to comment Share on other sites More sharing options...
