Volume Relay Attenuator ?

I designed passive volume attenuator few year ago with Peter Daniel. This module worked like a standard potentiometer with constant input impedance and range from -60dB to 0dB. I used OSRAM display (like the one used in Mark Levinson products).

https://home.comcast.net/~youngc1/Aleph P 17 Parts List.xls


Update:

From the looks of it there are a few errors in that build list if i'm not mistaken. please correct me if i'm wrong. quantities for parts are greater than necessary.

• Missing IRF9610 and erroneously has them all listed as all requiring IRF610. (T3 and T10 should be IRF9610, and T1, T1, T2, T8, T9 should be IRF610 right?) item number is listed obsolete, replacement needed. (im planning to order mouser 844-IRF9610PBF and 844-IRF610PBF)

mouser 71-RN65D-F-33.2 (0.5W) preferred over listed 71-RN60D-F-33.2
mouser 71-RN65D-F-22.1 (0.5w) preferred over listed 71-RN60D-F-22.1

Missing 505-MKP410/250/10 10uf pp mkp4 caps x 14 or equivalent.


Has anyone else spotted any errors in that list?

--------

Thanks again. Do any of these parts NEED to be value matched? (Ive never done matching before, as my current project (Pearl II) came with matched JFETs where it was necessary.)
