Mesa used Fender transformers for the Princeton Boost's, but they have had Shumacher make their transformers to their specs for decades.
The EIA 606 code is for Shumacher. The new transformers are EIA 166, but I still think they are a division of Shumacher. The 105,X101,100, 562003,562004 and the old SC-152019B were all made by them.
The only other transformers I have experience with are DeYoung and Dagnall. The DeYoung is in my SLO and the Dagnall is in my 2555 Silver Jubilee. As long as you have the spec, MM, DeYoung, Heyboer and a few other companies can wind you whatever iron you want. MM makes current Mesa style transformers for PT and OT upgrades.
