PH 2 to 3 schematic/values

G'day ... does anyone have component values for the phono 3? - specifically -
C13/14, C9/10, C15/16, R19/20, R21/22, R29/30, R31/32. I want to dble-check with what I figure these values are, based on various posts on this forum detailing RIAA values & new PS bypass arrangements from PH 2 to 3 versions. I have a layout of PH3 from a borrowed April 2007 Hi-Fi World which gives numbers. This is quite an exercise following the component numbering changes from 2000 to ph3!
cheers ... cb

Hi, which version of phono 3 ? As I understand it, the S (switchable) version has a different layout and I assume different parts labeling, to the non S version. My non S didn't come with the 3.18us mod (I fitted it later)

My phono3 non S version has the following:
pcb is marked "WADPHONO11 issue 2"
Parts sheet list
R13/14 47k 0.5w carbon film.
R15/16/35/36 1k 0.5w carbon film.
R17/18 1k2 0.5w carbon film.
R19/20 100k 0.5w carbon film.
R21/22/37/38 1m 0.5w carbon film.
R23/24 316k 0.25w metal film.
R25/26 39k2 0.5w metal film.
R27/28 2k2 0.5w carbon film.
R29/30 330k 0.5w carbon film.
R31/32 180k 0.5w carbon film.
R33/34 150k 0.5w carbon film.
R35 (was a typo should be R41) 1k 2w carbon.

The capacitor pairs for mine dont match your list.
Mine are listed as:
C10/11 0.1uf 250v orangedrop
C12/13 10uf 400v radial
C14/15 8.2nf 1% 160v silver
C16/17 220pf 630v polystyrene (silver)
C18/19 2.2uf 250v orangedrop
C20 100uf 500v radial

My phono3 was one of the first ones, I don't know if the later ones are different.
Hope this helps.

OK thanks for that ... yes the numbering is confusing. I have a series 1 phono 2 board that I've had for years & finally stuffed it .... I also have a PSU 3 board which I ordered & have adjusted to suit the RIAA board only, as I have tube reg'd boards already done for the line level aikido boards. I believe the original WAD PS board had PS bypassing on that board as per the PSU3 PCB but the phono 3 signal circuit has additional bypassing on tube 3 ... this is marked as C15/16 & I'm assuming its ~100uf@450vdc altho this sort of voltage rating isn't really necessary. The phono 3 has a number of mods which I gleaned from various sources & a member supplied me with a component list for the PSU board. This exercise is about dble checking my modding the phono 2 PCB & PSU 3 to match the phono 3 circuit. Its nice to see it all on one schematic, however the only phono 3 diagram I have seen doesn't have component values just the new numbering.

cheers .... cb

I've sent you the diagram and build instructions by email so you can see the differences.
