Carver TFM-6C Recapping
Recapping: With the recapping kit for the Carver TFM-6C amp, we focussed on replacing the large 6800 uF capacitors. Although holding acceptable values, we saw corrosion underneath so it was good time to remove them before they could leak and cause damage. Idle Current Adjustment: After replacing the capacitors, we adjusted the idle current for each channel. We initially measured it to be nearly 2x the specified value for this amp. Each channel was initially reading 9 mV across the reference resistors but we set back to the desired factory setting of 5 mV using the adjustable onboard potentiometers. It could be our imagination but the unit seems to sound a little clearer at the low end and maybe even less distortion at the high end. But even if sound quality improvement is subtle this circa 1990s Carver amp is future proofed from major capacitor leaking for years to come. Below are some before and after photos.
