Let's bump this again after some years!...
Hi all
1) I've not seen anyone comment on brands/types of capacitors recommended for this circuit - particularly in the riaa feedback network. I am considering these (but from a UK source) Vishay R. Film Caps
What do folk favour please?
2) What about the other components - any tips? Will use normal metal film Rs.
3) Also what is the expected current draw from the 24V supply - I reckon somewhere in the region of 60mA per channel?
4) Finally - those unusual resistor symbols for R102, R112 - diagonal stripe across one end. What do they mean - not found the answer on the 'Net?
Many thanks
Pete
1) You can use cheap Wima MKP10 capacitors. For best results select those to match 0,1uF +/- 2%. Initially they are delivered with a +/- 10% tolerance which is unacceptable high.
2) Normal metal films are fine.
3) Current draw is really that high.
4) The unusual symbols highlight a power rating of 2W for those resistors.
Hope to have answered all your questions.
