This board replaces the large can capacitors in the power supply section of the Dynaco SCA-35 Integrated-Amplifier, as well as the B+ rectifiers and the single cathode bias resistor for the output tubes. Exact replacements for the original can capacitors are difficult to find. The values needed can be built up with various replacement
caps, but the installation of all the needed capacitors tends to make the amplifier very messy. This circuit board uses readily available circuit board mounted capacitors. There is a large range of values and voltages available in this form factor. The board easily holds similar capacitor values to the original can caps with room to spare. The capacitor values can be increased substantially and still fit on the board and in the amplifier. As an added bonus, the cost of all the caps needed is almost the same as a single modern twist lock capacitor. This board also allows the single cathode bias resistor to be replaced by a single resistor for each channel. These resistors are bypassed with an electrolytic and a film cap for each channel as well. There are provisions for film cap bypass on all filter sections. This board bolts through the chassis using 8-32 standoffs and will use the holes that the original can capacitors
used to attachment to the chassis. Board only, no parts.
