whatever, I will probably choose a bigger 19" box
the small one will be ok too, but for a smaller project
it does have a nice back, but not much space for connectors etc
so I cut away most of the old tuner front plate

moving on/off switch from the front to the back
Im using the hole where the removed mains voltage selector once was

looks like this preamp could turn into a 2-box affair

wow, I had no idea a piece of 20year old and scratched poly plate could look this cool
just a bit of matte spray on the back, and voila, a fancy looking front

hey, juma, are you watching ?

would like to ask you if you have a suggestion for a good simple gain stage with the J310
could the j310/CCS buffer be changed to a gain stage ?
