Post Subject: More "literature" about my faulty power supplyPosted by Romy the Cat on: 1/16/2008

Well, the subject of capacitors in that PS should be resolved. We discussed it a lot with Dima and he feel that I am fool all my idea to try in this supply “minimum capacitance”. He actually does not believe in small capacitance, he has a vision how the last capacitor participate in signal path and according to him the last cap should be large. Dima feels that zillions of SET out there with 20uf or 60uF capacitance the plate sound as horrible as they sound because the imposer recharging pattern of the last cap (one of the reason) and therefore the PS are improperly decupled from tube plate. I do not know if it is correct and if it is play in my case. I never experience any problem with PS sound but I always used very large last cap. According to Dima a sufficiently-large last capacitor with using in input choke make the sound or transformer, rectifier and choke less relevant. It is possible that he is right as it was my very first PS where the last cap was less than 2000uF -3000uF. Perhaps now, with “minimum capacitance” the maternal of the caps begin to “sound”.

N-set, you said that switching of my diodes has a lot of room to be better; could you elaborate could/should I manage it?  Thanks.
