The ones with no info (such as 100, it’s supossed to be ohm) but, also no info about the ot! or the output is 5w but at 4, 8, 16, 32 ohms???

What ratio the OT? Hi, I agree with Rui, some more detail would be good. What ratio the OT?

For example, power line B is connected to EL84 by a 1kOhm/1W resistor. Power line C is connected to the 12AX7 by a 100kOhm resistor. How many Watts for this resistor? Several resistors are not fully described. The voltage specification of the signal capacitors is also not explicit in the circuit map. Is it that evident? yet, when I purchase a 100 uF capacitor someone will ask me «how many volts?» I suppose I'll have to try and burn a few parts before I get right.
