Hi everyone. Sadly 3 pots on my 1979 LS60 has spoilt. The shafts have loosen and couldn't be used anymore. The plastic disc inside the pots have disintegrated into tiny bits. It has the PCB board. The 3 faulty pots are 1 tone and 2 volume. I've removed the PCB board and found out that the 2 tone pots are labeled A500K and the 1 volume pot is labelled B500k. I know that the volume is linear taper and tone audio taper. Should I get the replacement pots all audio taper or audio taper for the tone pots and linear pot for the volume as per original specs? The funny thing is that the volume pots doesn't sound like a linear pot doesn't sound like one. It sounds more like an audio taper pot to my ears. Very gradual taper. So what new pots should I get? Thanks for taking the time to read my post...
