A wetting balance includes a load cell for suspending a specimen above a crucible containing a molten braze pool. A lift supports the crucible for vertical lifting thereof to effect an immersion cycle of the specimen in the pool. A controller operates the lift and determines first contact with the pool by measuring force changes thereat and produces a measured force log during the immersion cycle. In operation, the lift is operated for a predetermined time following first contact for immersing the specimen to a predetermined depth in the pool.

An intermediate frequency amplifier stage includes a tuned circuit which is shunted by a transistor utilized as an emitter follower, the emitter follower being responsive to the amplitude of a detected signal to lower the 'Q' of the tuned circuit as the amplitude of the detected signal increases and to increase the 'Q' of the tuned circuit as the amplitude of the detected signal decreases, thus effecting the gain of the intermediate frequency amplifier stage inversely respective the amplitude of the detected signal.
