Default Remove muting transistors on Arcam CD73?

Anyone here have any info on removing the muting transistors on an Arcam CD73? I have never attempted any DYI upgrades of this sort and would greatly appreciate any feedback or help.

Thanks in advance!

I don't have an answer to your question, but in general it is a risky practice to post an unprotected email address to an open forum like this.

A grazing spam bot will eventually find it and you have no idea how much spam this can result in...

I've requested a moderator remove it. Yeah, I know I'm a busybody..

Safest practice is not to post any email address which is not always practical, but they can be disguised so that they are not useful to bots..

Example: namelessperson_at_anyoldisp_dot_com is just one way of doing it - underscores can be left out if desired.

On Topic:

Google for the service manual.. Muting transistors can often be reworked to drive a relay instead which shunts the audio out, retaining mute without nonlinear dirtysand in the path.

Other items to think about:
replacing op-amps
output jacks
supply filter caps
