We are distributor for Allnic in Denmark and Norway. It is correct that Allnic uses the new TungSol KT170 in their new T-2000 30th anniversary integrated amp with extremely good results.
I had read somewhere someone said that you could just replace the KT150 with the new KT170 for instance if you owned the former T-2000 amp. Therefore I asked Allnic and their response is that the transformers in the previous T-2000 are designed for KT150. Therefore it is possible to replace but sound may not be optimal. So you should check with your dealer or the manufacturer before you do this.
