  • Notes

  • Rider's 13-5 (Aligning, tube placement) shows that models 600H, 900H (in Brown and Ivory cabinet no. 33528) and 900J (Burgundy and Ivory cabinet no. 33961) share the same chassis no 33527 and 13-6 (schematic) shows the same schematic for 900H and 900J, which are for AC 25-60 cycles and DC. Stickers and details at Rider's show a hyphen - so we do too. Tuning range is 0.54 to 1.65 mc. Stromberg-Carlson model 900-J has a cabinet from Ingraham & Co.
