According to a post by Joeinid on another forum, the new GAT series II will use PCC88 tubes.
"Additionally, the tube complement is changed to incorporate PCC88 tubes, of which we have acquired a stock that we are reserving for GAT preamplifiers"
In my mind that could be taken as a kind of recognition/admission by Conrad-Johnson that the GAT is hard on tubes since PCC88 are 7 volt tubes (like 7dj8) rather than 6.3 volt for 6922. That is only in my mind though - they have not admitted anything in reality.
