JJ Electronic – E88CC / , 6DJ8 – gold

So with them, what you pay datashert what you get. With good test value also, but these we could not match. Left tube on the picture.

Also you should try the Svetlana types 6N1P. Number “2” would mean outside Germany. This is a much improverd version of ECC88 made, with higher voltage capabilities, higher plate dissipagtion, and better in many many ways. Lucky on internet auction sites. These were made for the military, as you can see from the sword signs on the back side of the tube.

Set it on AC, and if nothing is read, dahasheet it on DC.

Anyway, not reading the datasheet may work with most tubes, but not with all. However they bias not as trhey shouls in all circuits, and have slightly lower gain. All from the same factory code.

You can order any pair you like, as long as we have it available. Clear white print like new, from spare equipment. Some tubes from equipment are sometimes actually never used. To give you an idea, the size of a large bacteria is 5um. Read below, how to connect the voltmeter.
