As already said, this piece is a rebranded Marantz. Mine is rebranded under the name Expert TA-960, but is similar to Superscope R-1270.
I really like this receiver, it sounds very good! And it is dead beautiful too, with the blue radio scale.
I have tried a few midpriced receivers and amplifiers over the years - Nad, Denon, Technics, Kenwood and Akai - and I must say that this is one of the best I have ever heard together with Akai.
Playing vinyl or CD just sounds right through this receiver. A nice warm sound with lots of detail and punch. Never fatiguing. It is simply fun to play music, and that is the best review a piece of hifi equipment can get, to be honest. A lot of records that seemed to have an average or dull sound quality before, sounds excellent through this reciever. The only drawback is the radio section which has a weak reception, but that is a small remark considering the great sound from all other sources.
It has a lot of power too. Seems to be more than the 35W specified here on HiFi Engine. More powerful and loud than other receivers/amps with similar specs.
As an extra bonus I was lucky enough to get it for free from a lady who could not get it to power up. I cleaned it, changed the power chord, added new lamps and then I was ready to go!

re: R-1270

This is 35wpc. Amp section is based on Marantz 1070.

re: R-1270

There are similarities with both Marantz 1070 and Marantz 2235. But: Superscope R-1270 and Marantz 2235 have the same output transistors, Marantz 1070 has different output transistors, so it's probably closer to 2235.

Adjustment procedure (DC offset, idling current) is basically the same for all three, but note that the emitter resistors in Superscope R-1270 have a different value than in Marantz 1070 and 2235, so the voltage measured across them should be corrected accordingly.

re: R-1270

Superscope are using a TA7129P IC for phono . Only Marantz 2215B (and not 2215 or 2235 or 1070) are using same IC. That TA7129P are rare item today. Happily I have a few extra if someone need.

That IC is in Marantz 2216 too. But yes, looks like the R-1270's preamp, tuner and phono stage are borrowed from Marantz 2215B.
