The EL844 is exactly pin compatible to the EL84 ( 6BQ5) output valve and it has an interesting twist.
It is highly popular in the USA and it was orginally developed by JJ Electronic based on feedback from the USA.
The valve is 9 watts versus the 11 watts of the EL84. The big benefit is that it the valve breaks up earlier. This is very handy when practising so that the rest of the family in the house and the neighbours benefit too.
You get the cranked up sounds of your amp at lower volumes as compared to EL84’s It will give you a different rock sound and so brings new character to your amp with only a valve swap out. This is excellent fo ramps like the Fender Blues Jr. Although valve is very popular in the USA but , so far, not readily available in the UK, and we have them in stock.
We give 120 days warranty on all our valves and all are tested by us.
