Phono for Bride of Zen

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.

Many thanks Ivo - really looking forward to getting this going...

I'll be constructing it using my favoured PCBless approach for simple stuff => using the largest parts as a skeleton for the rest, fixed to a suitable chassis.
