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.
