RGN2504 Telefunken KL76303 Klangfilm balloon directly heated rectifier rare! U12 U14 U18/20

Telefunken RGN2504 £ 180.

Description

The Telefunken RGN2504 can be considered a masterpiece of a valve.

It is quite impressive for what it is!

The plate is located at almost half the size of envelope.

There is quite a ‘space’ between top dome and top mica surrounding supporting springs thus the valve cools off quicker than most of its rivals!

Black plate allows stunning heat dissipation.

Can be used in place of U12 U14 etc. Being a full-wave directly heated rectifier.
