Hello,
I currently have an old Urei 1176 Revision D Limiter on my bench.
At first I thought the voltage is a bit off (28V instead of 30V)
but when I inserted some new light bulbs, the power dropped to 25V after the regulating zener diode.
I disconnected the 3 wires from the transformer and measured 32 V AC (unloaded) on each secondary winding. I assume this is too low. The input voltage is 230V AC (schematic says 240V , btw)
is this a normal behaviour, maybe because the input voltage is too low, or do you think the transformer is defective and I should use another one...
thanks,
matthias
