For Sale La Radiotechnique R120 tubes, NOS matched pair, IDTH 2A3

[Klimon]

I'm offering one perfect matched pair of NOS R120 triodes for sale (= 2 pieces). Fully tested with Etracer, including curves.

La Radiotechnique R120 is a French indirectly heated triode produced in the 50s. Bling-bling: Jean Hiraga rates it highly in his book on triodes and it apparently won a listening test at the European triode festival from the likes of WE 300B, AD1, PX4, PX25.

Tubes are identical production-wise, with same date codes and matching is exceptionally tight:

Test conditions: 250v anode | -35v grid
Datasheet specs: 60mA (= 100%) anode current | 840R anode resistance | 6.4mA/v gm | 5.4 mu
Test results:
Tube 1: 66mA (110%) | 797R | 6.66mA/v | 5.3
Tube 2: 64mA (107%) | 812R | 6.52mA/v | 5.3

I'm asking 575 euros for the pair, including shipping in Europe at my expense (I live in Belgium). Priced to sell... you won't even find two non-matching R120 tubes anywhere near this price point 🙂

Here's the amplifier I wanted to build with them. Let me know if you also need a pair of nos Mullard ef37a.

Cheers,
Simon
