I used to use a couple of 6 volt lantern batteries(I used to get them real cheap ) on my CD94 11 to a Trichord ,So I know the excitement you are feeling Jehuty .
There were no down sides to running a clock with batteries .Everything was better . I loved the purity ,and when you run electrostatics ,any grain or grit is very apparent .
I also found that I could listen to more marginal sounding CDs with a battery powered clock .
I often read about people criticising modding, saying that you can only listen to well recorded CDs ,and less well recorded CDs become unlistenable ,but if you reduce distortions and noise from the playback chain ,then most or all CDs should sound better .
If I do a mod ,I want it to sound better across the board ,or at least do something better ,with no other down sides .
We should all be running battery powered clocks .The Valab is an excellent value clock probably due to better regulation than the Trichords ,and it is critical .Valab also have a higher tolerance crystal ,but I don't know if there is any advantage over the one they put into their clock .
Next stage for me is to get hold of a zen clock once Zenelectro is back on board .
Any photos of the finnshed CD94 Jehuty ?
