Description

Here is another audio gem. This is the "Shiny Eyes" 45-C3m SET DHT amplifier, built with care and to provide a rewarding sound. This is an audiophile amplifier and it is not for everyone. It delivers up to 2W output. These 2W sound bigger than it shows. It is indeed a 2,000,000 microWatts. It is meant to be used with high sensitivity speakers. The amplifier has one output  through a high end Cardas binding posts and one input using Vampire CM1FCB RCAs.  The output transformers are Electra Print low IMD and the interstage transformers  are  Lundahl LL2762/16mA.  The 45 tubes filaments power is supplied through a Coleman regulator. Therefore there is a need to adjust the filaments every time the tubes are  replaced. A 5V high quality Simpson meter is used for this purpose. The amp comes with a manual where there are easy to follow instructions on how to adjust the filament voltage.

The power supply has a separate enclosure. The high voltage uses a Sony/Tamura TC500 power transformer, Hammond filament transformers and chokes and 6AX4 tube rectifiers. The setup is a choke input for a better sounding amp. The high voltage delivered to the amp is measured and shown on a nice Weston 500VDC panel meter. There are 3 raw, well filtered and regulated DC supplies : two for the 45 filaments and the third for the C3m filaments. The power is supplied to the main amp through a screened umbilical cord that carries only DC. The connector is Amphenol military grade. This way the AC is kept away from the main amp and the amplifier is dead quiet on my 96dB speakers.

All the components are high quality and audio grade. The 45 tubes sockets are high quality vintage NOS Amphenol and the C3m sockets are original Siemens. The amplifier comes with all the tubes : NOS 6AX4 - 2 pieces, pair of 45s test NOS Philco and pair of C3m NOS Lorentz.

The amplifier shows a dominant 2nd Harmonic that confers the absolute astonishing sound of a DHT from that era. The frequency response is better than 25-25KHz +/-1dB, the input sensitivity is 2.5 Vrms for maximum output, and the input impedance is 50Kohms.

The enclosures are hand made using American cheery nicely finish with 4 coats of Oil and Urethane, and sanded aluminum 1/8" top plates.

This is a well built amp to last for a long time. I am very fond of the sound of the 45 tube and therefore I've built a few 45 amps and always pleased with the results.
