I am almost finished recapping a model 16x (5 band) type 121. The tone control has two caps inbedded in the control and two in separate tin box. It is a 4 position control in position 1 a .006 mfd cap connects the plate of the 1st audio tube to ground in the next position it seems as though a .09 cap is in the circuit in the next two positions a .15 cap and a .5 cap are added to the circuit according to my schematic. The tone control had very little variation in positions 2, 3, and 4. There was no change after recapping. Is this typical? Could it be that the cap values on the schematic are not correct? The last two in particular seem a bit large for a tone control but my simple analysis would be that lowering the values would result in even less variation in tone between switch positions.

Thank you,

JT in Albany
