Description

The U50 is a directly heated full wave rectifier with oxided coated ribbon filament

We offer a set of four pieces Marconi Philips Mullard Osram etc. U50 is also one of the best selling valve here at Audio Magical.

We had many requests about this valve and its variation.

We thought it is our commitment to show all that is available for this directly heated full wave rectifier that was introduced in 1937!

All four U50 have black plate and cup getter

All four U50 tested with AVO VCM 163 with A1=A2 100% emission
