Hello. Anyone here build Zen headamp after 2003 ?
Original Article:
HeadWize - Project: The Zen Headphone Amplifier by Marcello Pellerano
I'm planing on building one. It will drive my Cresyns CS-HP700 (32Ohm) or Beyer DT880 (250) if it's owner will like this.
So here is my plans:
I'm planning to make handmade PCB (laserprint, have some exp). One symmetrical board for two channels. One trafo with two secondaries.
Power supply: all is as in article, but:
25VA 2*18V Talema (boxed, blue).
CRC filter: 6800uF caps from ca340a, R, 1800uF Pana FC.
Can I use R=4,7 or 10 ohms instead of 5.6 ?
I also have line choke filter, and X,Y caps for STEPS Power supply. And don't know, if it will be usefull here .
BTW choke is Murata PLA10AS3030R4R2B (30MH, 0.4A) If it has enough "current ability"?
Case : Hammond 1455-N2202 (220x103x53mm)
Main:
C2 = Wima MKP 2.2uf - If it's good choise for this position? I can get this for good price...
Thanks for Your attention
