    FYI the Marstran site doesn't provide...unlike "The Big Lebowski"

    Does anyone know where to find the Drake PT 1202-324 heater winding specs? In general I have found some specs for Marshall Iron "Drake" from the 60s and 70s but nothing really on the JCM800 2204. I really just need to verify the max current draw for the heater secondary.

    The JCM800 Model 4210 aka 2205 had five 12ax7 tubes and two el34 tubes and the same Drake 1202-324 PT as the 2204. However, there are some odd notes on the 2205 schematic that could be alluding to a different PT by Semko and CSA.

    I want to add two more 12ax7 tubes to my 2204 chassis for two mods, vibrato and FX loop. I would love to verify the 1202-324 PT specs to be sure it can handle 4.5A or higher current on the heater winding.

    Thanks for your help
