The supply caps to the output stage NEEDS to be big, as big as the tranny and rectifier diodes can handle.
A composite config of about 800V or higher tolerance is needed due to turn on spike.
Hardly anyone uses film for the output stage.
You need about 200uF for each pair of El34/6550/KT888 type tubes.
Driver and input/gain is different. Its the quality that counts. Figure 20-100uF.
