Difference between a Fisher 514 and a 504X
I am having a bit of trouble tracking down the User manual on this Receiver.
I have the Service Manual but it doesn't make it clear what the difference between a 504X and a 514 is.
I have a 514 and a mighty beast it is at 20Kg.
The only thing I have found is an advertisement listed on Ebay referring to the 14 series having a built in CD-4 decoder.
It looks as if the difference between the 304X,404X and 405X is just output power
Can anyone confirm that the built in CD-4 decoder is the difference between the units?
This is from around 1973 so almost 40 years old.
