All about electronic valves and hi-fi
I’ve got asked the question on how an EML20 (or EML30) can drive an EML45B. Answer is straight forward and hopefully this brief blog entry can shed some light to this request.
I recently looked back again on the EML20A. With a gain of 20, it’s a good candidate but it hasn’t got just enough gain to drive the output stage to full power:
There is one DHT which attracted me from Emission Labs which is the EML20. If you’re looking for a mid-mu DHT valve these days, this one is the way to go. In order to meet with the two key requirements of linearity and low microphonic noise, EML made a great effort in producing this valve.
For me it’s a great candidate as a driver or for a Spud amp for headphones. I will likely use them in several places, but will start with a preamp stage, as you would expect from me anyway.
