I hate the RCA 630 chassis

Generally, I use 1.5 K and 250 ohm 25W Ohmite 210 series adjustable wirewounds to replace the 2 sections of R185. Both resistors will stack perfectly end to end on the original mounting hardware. Set the adjustable tap bands to get the odd values of resistance needed. Order the mounting washer kits (p/n 7PA25) with the resistors, as the OD of the new resistors is smaller than the original.

The riveted in "candohm" resistor (R186) can be replaced with a pair of chassis mount 10W power resistors (Ohmite HS10 series or similar). I use 6.8K and 100 ohms, as the closest standard values, with no problems. You will need to drill new mounting holes, after removing the original resistor.
