Museum pieces: EL60

The EL60 is the true forerunner of the iconic EL34.


This tube was approved and placed in the Philips museum at Mullard in Blackburn and still has the entry code of Sept '50, the code on the base reads 57 M91.



Believed to have been made by Philips in Eindhoven. The valve itself has rounded anode plates, square micas with ceramic insulators. The structure is connected directly to the base and has radiators at the top and bottom of the tube (four in total).  The major difference between the EL60 and the EL34 is the B9G base


We'll get some more photos posted shortly.
