Yes, it shouldn't be bad at all with quiescent current 18-22mA from a couple of PP9s. Worth checking that if you haven't already, and if it's at all high a first port of call is C2 on the amplifier board, 200uF straight across the 18 volt rail so it can be very leaky and a shortened battery life is the only effect.
