I have a Jolida 102B that uses the same front end tubes as the 202. I currently use 2 Telefunken/Fisher 12AT7's and an orange globe Amperex 12AX7. This combination has given me the best combination of detail and tube warmth. Mullard reissues,Tunsgram & RFT 12AX7's have also worked very well (in fact I will probably switch to the Mullards when the Amperex dies) but unfortunately I have not found another 12AT7 that sounds as good as the fairly pricey Telefunken/Fisher. I hope this helps.
