Nardeux PP Output Oil Filled Transformer x2 Parmeko Partridge Tube Valve 6s33s

Description

You are bidding for one pair (2 pieces) vintage Push Pull transformers made by Nardeux in France. Similar quality to famous Parmeko Neptune series.
Extremely rare large and heavy transformers for very powerful Cost No Object DIY amplifier.
I supplied primary winding with 220V to get transformer’s details.
I got 14,3V, 7,13V & 3,56V on output terminals. These figures give you possibility calculate coefficient of transformation for all terminals. There are two identical center tapped secondaries. You may have different Raa in case of chose different outputs in parallel or series connection for your load.
For example Raa=3,8kOhm for 4 Ohm load connected to both secondaries in parallel.
Primary winding resistance is 27 Ohm only! Both secondary windings in serious connection – 0,25 Ohm. Looks great for low impedance tubes like 6080, 6s33s or EC360. You'll have wider choice of options in case of taking negative feedback option in mind.
Guaranteed to be in full working condition.
Shipping cost within Europe is 40 euro. Rest of the world - 200 euro.
