The obvious question is, what speaker is the amp hooked up to? All amp/speaker combinations are "systems", the sound of each dependent on the other. Why is it assumed it is the amp that is boomy, rather than the result of the amp/speaker interaction?
Problem related to Push-Pull or EL34?
Hej
I have compared my EL84 amp with an EL34 amp and what strikes me is that the EL34 amp is boomy. I know that my room has a problem in the bass region and it’s like the E34 amp makes this worse. So why is that? Both are Push-Pull, but my EL84 amp has got the original capacitors replaced to “ultrafast” capacitors. So this makes me wonder if there is any truth in what I've heard:
...the Push-Pull design in itself increases the bass and makes the sound a little boomy.
...you can counteract this by replacing capacitors to “ultrafast” capacitors.
...EL34 tubes by design emphasis bass frequencies.
This makes me very frustrated because I really like this EL34 amp (LM EL34IA) except for this bass problem. The amp is in my budget range and I need the 40W it gives (which means Push-Pull).
Any thoughts?
