Good Question on the power supply improvements - on the original design we just had a small choke on the Screen voltage for the EL34 stabalizing that - with the new design we added a much larger choke that handles both the HT (High Voltage) and the screen - Then we designed a new Power Supply PCB which uses two very high quality Mundorf Mlytic power supply caps - the first cap is a low 30uf capacitance ( ben was right!) - similar to the power supply design of our 300B single ended - then we use a 200uf 4 pole cap in the position after the choke! Fairly simple but good quality caps , good large choke and we have also increased the Mains transformer to have about 30% extra headroom - its a larger transformer - this means the transformer runs cooler and can deliver extra current easily when required as the music demands it - We had a few customers who went from the original version L4 to the new version and they told us the bass was tighter and more defined with more detail and punch - which is what a good power supply should do - so we are very proud of how the product has evolved - we are in a good position in that we are low volume so we can afford to enhance and tweak the product on a regular basis without being committed to large volumes through dealers - thus the continued enhancement of the product line !
