A lot of people are quite fond of their speakers. The electronics had a lot more competition than their speakers.

Look at the back stenak.
You will find five TO3-transistors there.
Four of them is for the two outputs, and the last one is for the PSU.

..Thanks The Tandberg Man, but I do not understand!
Look at the back? I have found the places on the curcuitboard, where to measure......But the question was do I have to connect loudspeakers, or make a short curcuit on the input?
I have not done this since the 1990s, when I build my The End(a danish power amp kit)...

I was reffering to the post where You couldn't find the third transistor on the power supply board. There is two on the board, and a 2N3055 on the back of the amp where You also find the output transistors.
If there is any deviation between the 303 schematics and Your amp, the power supply board possibly has been replaced at some time.
To meassure the voltage you do not need to apply signal, neither short the input or connect speakers.
