After changing defect lamps (fuse types) all lights are gone, all fuse types and tuning indicator. Reason??? Is there a fuse or a special reason known. All functions are working, just no light.

Hello Herbert,
are the function lights out too?
there is a fuse board bolted to the right power amp, check the fuses on that board, the one with the green wires connected is the lamp circuit fuse, put in a new one, same value, if it blows again, check for a short in the lamp circuit.
Btw, american versions of the 2270 don't have that fuse board!

Helmut, Your advice is best as usual. To everyone: Rüsselschorf is the "Pope" of old Marantz sets in Germany. You can trust his informations 100% .
Now his advice prefents me from opening the transformer, because in my american schematic these fuses are not existing.
Helmut, I put in a fuse M1.6/250V, is this oK, I found a T4/250V.
