Looking for a schematic for RCA RS147 or SP-20

Hi all, does anyone have a schematic for this amp? mono with quad 6v6 output?



The RS-147 as I understand it was the console version of the SP-20. I looked through threads but they all link to a site that has taken down the schematic

thanks

RS-147E schematic is available for download from Radiomuseum complete with rest of SAMS Photofact.

This is an old thread but for future references the drawing for an SP20 has minor differences over that of the RS147. And the power transformer, the OPT, and the choke have different part numbers as well. And the SP20 does not use a Candohm like used in the RS147.
