I've bought a marantz 1300Dc on markplaats.
This is the catalog photo.

mine has been build in 1977 in december.
When i got it some knobs where not orginal. One channel didn't work and i heard a humming sound(bad capacitors)
The front was in pretty good state. I also bought a marantz 2110 tuner. this one has a scope problem.
I totally replaced all the caps (except for the power supply board and the main amplifiers i;m doing that tomorrow)
I don't have all the parts now.
well here are the pictures.

:RECEIVERS:ending with B (2238B, 2330B)
I would really recommend looking for bad spots of Tin (Sn) and refurbishing it.
there are a lot of bad spots in this amplifier.

This amplifier sould give me 2x190watts minimum at an eight ohm load.
With a dual power supply, and 4x80v 10.000uF
hope you like it, will be posting the amps tomorrow .
