Dynaco Vacuum Tube Amplifier Restoration & Repair Resources

After an absence of several years, Pacific Audio Regenesis is preparing to re-emerge on the vacuum tube audio scene. The intent is not to revive the old AR product line, rather, to provide information related to the preservation and restoration of vintage Dynaco vacuum tube amplifiers. Information and articles will be posted as they become available.

Did you know?

Some of the most popular, and beneficial, Dynaco upgrade and restoration boards from the discontinued Audio Regenesis product line are still available, as bare boards only, from D. Gillespie Designs. Visit Dave's Store for more information.

Boards for the Dynaco SCA-35 Integrated Amplifier:

SCA-35*EFB™ Power Supply Board

Perhaps the most significant upgrade available for the SCA-35
If you do only one upgrade to your SCA-35, this should be it! Converts the SCA-35 from cathode bias to Enhanced Fixed Bias for increased output power, lower distortion and extended tube life. Also replaces all the capacitors, resistors and rectifier diodes associated with the power supply.

*EFB™ is a trademark of D. Gillespie Designs.

PC-10A Output Board Set

The PC-10A replaces the obsolete, increasingly hard to find, and expensive 7199 driver tube with either a 6GH8A or 6U8A. Note that this is not just a tube swap. Additional components have been added to prevent stability issues that can occur when these tubes are simply used with adapter sockets in the original PC-10  board.

PC-11 Preamp Board

Perfect for restoring your SCA-35 with modern components while maintaining the stock circuit configuration.

The original Dynaco component mounting hole spacing and eyelet placement is retained for easy drop-in replacement.

Boards for the Dynaco ST-35 Power Amplifier:

ST-35 *EFB™ Power Supply Board

Convert your ST-35 from cathode bias to Enhanced Fixed Bias for increased output power, lower distortion and extended tube life. Replaces all the capacitors, resistors and rectifier diodes associated with the power supply.

*EFB™ is a trademark of D. Gillespie Designs.

PC-13 Output Board Set

Perfect for restoring your ST-35 with modern components while maintaining the stock circuit configuration.

The original Dynaco component mounting hole spacing and eyelet placement is retained for easy drop-in replacement.
