Phono tube preamplifier TP 305
The CANOR TP 305 is a fully valved phono MM/MC preamplifier of dual mono construction equipped with high-quality MC step-up Lundahl transformers. Front panel is made of solid cherry wood with a quality paint finish.
The TP 305 tube preamplifier is designed with a view to the highest possible audio quality. This is tailored to the overall electrical and mechanical construction. To achieve the highest audio quality we used the EZ81 vacuum diode to rectify the anode voltage of amplifying tubes. In this fully valved phono preamplifier there are used seven pieces of tubes 6SL7, 6SN7 and 6922.
The first stage consists of two parallel triodes for reducing audible noise and ensuring the highest gain. Behind the first stage there is a passive RIAA correction. Then the second stage is integrated with the second passive correction. Output buffer provides very low output impedance. The active part is 40 db amplification at 1kHz. This gain is sufficient for the vast majority of MM pickups. Both MM and MC pickup can be connected to the input at the same time.Desired input (MM or MC) to select by the switch in the back.
To enhance the very low voltage gain of MC pickups, the Lundahl impedance matcher is used at the input. This solution has great advantage in not increasing the noise by the device itself.
