PST 100 TA Transformer Attenuator Preamp
• PST 100 MKII: Combo Valve & Transformer Preamp
In a transformer, however, the magnetic circuit can be ultra linear when the very best core materials are used. The sound of such materials is much more musical and detailed compared with the best resistors. So Ypsilon produced, in-house, a special transformer attenuator with 31 taps.
The active gain stage is a no – feedback s.e. triode, transformer coupled. The power supply uses valve rectification and choke regulation. Wiring is made with custom made pure silver wire. The transformer attenuator is placed after the valve stage, preserving the purity and micro details of the signal.
The maximum attenuation is 52db and maximum gain is 12db. Output impedance is 150 Ω max. PST is the pinnacle in preamplification. It is a must have component for building a “no holds” system.
