Hi guys;

Still repearing and restoring a old fashion boy of  a TL911 amp.
I have removed the HT transformer for cleaning brushing up a bit and after 
doing some meassuring with a shunt resistor in series with the primary of 
47ohm/50W 
connected to the 220VAC net, I measure about 47VAC with a FLUKE over the shunt 
resistor.
This means that there flows a "non load current of 1A".
With other words there excists a dissipation of about 47W with no load !!
May I conclude that there is a broken coil inside this transformer ?
But nothings becomes warm or hot,so I presume a coil failure will produce some 
temperature dissipation ??
