Renovated EL156 Single Ended Amplifier

Telefunken EL156 seem like a king of pentode tube that many people want to taste.

My friend also bought a pair of mono-block EL156 single ended amplifiers

with all Tango transformers from ebay.

But he need new enclosure, tube rectifier and use Western Electric components.

So these are what we did with those requirements.


Original enclosure of EL156 mono-block with EF80 driver.



Wiring inside / diodes bridge rectifier.


Hirata-Tango FW-50-5S output transformer.


Hirata-Tango NN-6 "Permalloy core" input transformer.


Hirata-Tango MS-360 power transformer.
