I had purchased (2) Hammond 159ZA filter chokes as per Jeff Medwin aka Drlowmu some months ago for future LSES power supply filter experiments.
I was wondering if my (2) Hammond 159ZA filter chokes would be suitable in building a single filter chain for the SE DC 6AQ5 stereo project amp I have been developing.
My concern was if a single LSES filter chain to the finals would have low enough AC ripple to be worth implementing in my particular project.
I honestly don't know what the current "state of the art" implementation for LSES would be in June of 2019 but I recall something about no capacitors over 50uF, so I used those 50uF values in my PSUD2 simulation.
The LSES filter I ran is : 300mH/1A/6 ohms -> 50uF -> 300mH/1A/6 ohms -> 50uF -> a single filter chain for both channels.
IMO, this LSES filter is a high AC ripple type of filter that would need careful implementation to execute correctly. The choice of finals, the mu in particular would probably be another thing to consider.
In my stereo SE DC 6AQ5 circuit, I would need (2) LSES filter chains - one for each channel. Even with that approach, I might need to add more filtering for quiet circuit operation during idle (zero signal conditions).
If I go beyond 50uF per cap, is the filter really a "low storage energy supply" , maybe not in such a case.
Since I am primarily a user of well-filtered "flywheel" power supply filters in my low DCR SE amplifier circuits and not so familiar with the sound of the LSES filters, I will not pass any final judgement.
Computer models are one thing, but "build and listen" on Altec horn systems takes everything to a new level of gnosis.
