After many years we had CTS make pots especially for us. Based on the 450 series 15% B taper with brass shaft and thread and with a + - 5% tolerance and slightly higher nominal value so that the values do not drop so much from the stated value, but still marked 250K and 500K to keep the look vintage correct. The “CG” pots are audio log and suitable for volume and tone.
