Bought the kit and did the install. GREAT addition to the VTA and gives the unit a classy upgraded look compared to staring at the Dynaco preamp sockets. Will installl panel mount test points to fine tune bias with a DMM but these look great and will give indications if something goes wonky. I got scraps of 35 grade darkness window tint from a local shop to go over the lexan. (in Dan's instructions too) Can't see the the readouts when the unit is off and provide a nice subtle blue hue of bias voltage when powered. Dan is working on version 0.2 of the kit with tint material or darker lexan. Will try and post a pic.
Highly recommend.
