Motorola 259M

You may not be successful in finding a replacement but others may chime in. Has this unit been re-capped/refurbished? If the only problem is turning on-off then I would suggest shorting out the switch and using a power strip to operate with. On many of my old radios I will switch them externally than to increase any wear and tear on a part that is difficult to replace.

You can do this temporary if you wish until a suitable sub/replacement comes along at the least and still be able to enjoy it.

Thanks for the suggestion. This could be a solution. I have not recapped the radio yet but I will be ordering the parts soon. I got the radio from my BIL just to get it out of his garage. It does play on AM but FM needs work. I have the switch bypassed at the present time and just plug it in when I need to power up. The controls are all smooth with no static . I just did not know if it would make a big difference for a Bass control if it is linear or audio taper. I could also use a schematic for the AMP132aa if anyone would help out. I was looking around and was able to find a schematic for a AMP132 but not an AMP132aa. I really don't have a clue what the difference would be. Thanks for the reply.
