| [#1] EL34/6550/KT88/KT90/KT90/KT150 tubes Compare the specification from EL34 up to KT150 which can be directly replace. Please note the beautiful Tung-Sol KT150 shape I have ordered one Quad set and going to insert in a Jadis Integrated Amp to replace KT90 in next week and see what happen!!! Very Very interesting!!!

| [#3] EL34/6550/KT88/KT90/KT90/KT150 tubes I have one secondhand Jadis Orchestra Reference come with KT90 factory setting， The last owner replaced with 6550 because one out of four KT90 is not function properly I find the specificatio of KT150 is very close to factory KT90 settings than other KT88/6550 Tubes， so I decided to replace with the Tung-Sol KT150 and see what happen, I will get the new tubes in next few days and desperately to hear any changes! As soon as the KT150 function properly, I will try to increase the output power of This Jadis from 40 watts up to ?? Watts, since the maximum output of one pair KT150 Factory claims 300 watts!

| [#6] EL34/6550/KT88/KT90/KT90/KT150 tubes EL156 has a max plate dissipation of 50W which makes it as least as powerful as KT90, and probably more refined. |

| [#7] EL34/6550/KT88/KT90/KT120/KT150 tubes I agree that I am not quite satisfy with the performance of KT90 in my existing Jadis and that why I try to upgrade to new KT150. You may find a lot of test and comment about the new Tung-Sol KT150 on internet. Dr Chan |

| [#10] EL34/6550/KT88/KT90/KT90/KT150 tubes KT150 can be used in any MC275 because it can tolerance higher working voltage and power compare with KT88 or 6550 But you have to adjust the bias I bought matched quad set from oversea at USD 333 per set Dr Chan 最後修改時間: 2014-01-23 21:48:24 |

| [#17] EL34/6550/KT88/KT90/KT90/KT150 tubes 多謝Dr.Chan師兄解答，不過剛買了8支kt120作後備用，最快要等多年先考慮換kt150，或者到可確定ARC能否使用kt150來取代120。 |

| [#20] EL34/6550/KT88/KT90/KT120/KT150 tubes 我相信現在用僅EL34/6550/KT88/KT90/KT120 都可以升級改用KT150 只需要檢查和微調以下各點： 1. 買新KT150 4隻新膽要確保特性相同（特別別是推挽放大線路） 2. 由於KT150 的燈絲電流及滿載電流都比其他膽較大，需在換膽後檢查火牛 有無過熱，過熱很快燒牛， 3. KT150 比較其他膽需要多些散熱及安裝空間，即是肥D及高D但腳座一様， 4. 微調靜態偏壓及hum balance, 每部機要求的工作電壓及靜態電流都不同 ，影響工作點在甲類或甲乙類放大。 5. 但無論如何，換膽後只會更好聲及更耐用，很難番轉頭 6. 根據Tung-Sol 廠提供數據KT150 亦可用於純甲類單端輸出線路 約25Watts輸出功率 比845 平靚正好多，有空我將我部科寶845 換KT150 試下好唔好聲。 我預計而家賣僅KT88膽 貴到無論好快要收檔！ 由於我而家仲系日本滑雪，我部Jadis 用僅KT88準備換KT150 要過幾日先有空玩！ Dr Chan 最後修改時間: 2014-02-01 16:24:29 |
