Apollo Preamp


Continuing our work in the area of fine preamplifiers, Apollo tube preamplifier was design. With the success of the volume control. We combine our TVC and our tube preamp together in a single chassis. Thus making a superb combination, getting the best of both worlds

Owners of solid-state amplifiers were kept in mind during the design phase, zero offset voltage. The transformers maintains a zero offset voltage. The transformers has a physical isolation thus protecting precious amplifiers and speakers from damage. All the outputs of our Apollo preamp are electrically isolated.

Design Format
What makes our preamp different from other manufactures is the usage of the output transformers. Most preamps in the market are either cap-coupled and OTL design. This may not be the perfect match in terms of impedance matching. Feedback is often used in this types of preamps to lower the gain and the output impedance. We however opted to use the transformer to perfectly match the preamp tube to power amplifier at the same time lower the gain and the output impedance. Providing the effortless sound that we are known for.

Extra care was place in the power supply. By using a separate unit with tube rectifier and LC filter reduces power supply noise. The power supply quality is very critical  to bring out the nuances in the music

The Apollo preamp was design in such a way to maintain the strong sonic character of the TVC while providing gain and dynamics drive. Specially attention was paid to prevent the tube stage from changing the wonderful sonic character of the TVC.

However if a more colored sound is required, a simple swap to the 6cg7 tube would add the coloration and body to the preamp

Parts Selection:
Tube selection is made to achieve sufficient gain and output power with only one triode. Russian 6n1P is well known as robust and very linear triode. With our high quality output transformer, we opted for zero feedback design. Thus maintaining the musical flow of the preamp. Direct heated rectifier tube 5y3 provides low noise level and soft start without the normal transient effects. Implementation of other quality parts Mundoft Capacitors, allen bradley carbon compostion resistors, silver rca, ebony knobs and etc
