I open this thread for those who have problems with the voltages
required to operate the oscilloscope on the marantz Model 18.
The defective -500V is a recurrent problem on the transformers of this Model,
but if you are lucky that the other voltages are correct,
it is possible to add a small...
I assume they will lock if DC current is sent to the loudspeakers, but I have never seen them engage.
And it is not these relays that snap after a few seconds at the start of the receiver.
Besides I never find out how the delay works at startup ...
Any idea?
Here are some pictures of a Marantz 18 with black façade:
These facades were provided to me by a friend in France.
I can not get you in, but if some are interested, I think TMZ2 can make them.
