Motorola 259M

[skillybob]

Greetings to all. This is my first post on this forum but I have been lurking around trying to get some answers to my current project,which is a Magnavox console radio (model 259m). I'm not having much luck on my own so I thought I would ask the members for some suggestions.The radio is composed of two chassis , the tuner (CR330aa) and amp/power supply(AMP132aa). The switch to turn the unit on is part of the tuner and is mounted to the rear of the Bass control. The switch is not working so I thought I would try to replace the pot/switch unit so, here is my problem. I have located a couple of replacement options with Mouser, but don't know which one would be best. I have a choice of a linear or audio taper pot. What would be the best, or does it really matter for a Bass control? I could see that it would make a difference for the main volume control -- I'm just not sure. I actually may not have an option because the linear pot available from Mouser is 1/2 watt and the audio taper is 1/4 watt. My schematic shows the pot as 1/2 watt 1 Megohm with a spst switch.
If I haven't confused anyone , I would appreciate any and all opinions.
