Nothing done with the 3.5 of late as I have been busy with amplifiers and speakers. Still running all the power supplies (4 transformers, 6 secondary windings) , alwsr, flea powered tentlabs clock, flea on dac pin 28, TPR4's, cap mulitipliers, acoustica style LED modded LM317's.
Even the PFM mosfet gyrator (piglets dad) is still doing sterling service in front of all the LM317's in the digital section prior to the dac.
Thoughts have returned to the 3.5 of late. Started reading diyaudio.com again. I do it in fits and starts as much of it is over my head and fatigue sets in. Anyway, I was reading some random thread when Jan Didden popped up in the conversation and mentioned his fairly new silent switcher psu. I remembered Jan had something to do with Jung super regs and ALW used to mention him from time to time.
So, been looking into the https://linearaudio.nl/silentswitcher which is a switch mode psu specially designed by Jan for audio. Thinking about giving it a try in my 3.5 for what ever it is suitable for. The thought of getting rid of all those linear psu's (instead of adding yet more) is quite refreshing yet I am sure there would be some problems to over come.
Also I worry about how long a SMPSU will last compared to a linear one which can still be going 30 to 40 years later. Also have to get past the bad reputation these switch mode things have gathered with regards to dumping noise on the mains and RFI etc.
Seriously considering getting one or two
