    PAS volume and balance pot replacement question Empty PAS volume and balance pot replacement question

    Post by Dingojazz Wed Jun 10, 2015 7:54 pm

    Hello All,

    Having completed the VTA PAS "ultimate" upgrades, I'm planning to replace PAS 2 volume and balance pots with ALPs pots, and am wondering about the "stereo-mono" pot connections to volume and balance.

    If the ALPs pots go in for balance and volume, can the "stereo-mono" switch connections be bypassed/omitted completely with impunity?

    Thanks

    i gather from archives that this is a bit of a can 'o worms, so to simplify, I'm just trying to see if those stereo pot connects need to be maintained.

    If it's still too sticky I get it.

    Thanks

    99.9% of people upgrading to the ALPS volume and balance control do not bother with the mono/stereo switch, so that can be totally bypassed.

    You may wish to keep a simple stereo-mono switch. A stereo-mono switch can be useful for those who play mono records or listen to weak FM signals (if the signal is weak, mono FM is less hissy than stereo). A simple SPST switch is all that is needed and in stereo mode it is totally out of circuit, as nothing passes through it.
