Thunderverb 50 Gain Pot

Hi All,

I have a Thunderverb 50 and the shaft has broken off the Gain pot. I've removed it and it's a dual-gang type marked as 105A. I know it's 1M ohm but is it Linear or Log? The old style marking for Linear was A and for Log it was C but the new marking for Log is also A. Anybody know which type I should be ordering for a replacement? I can't find a schematic to check which it is.

TIA
Bob
