I was really concerned about the plate since I didn't have any good reference...but since you asked he's the whole scoop.
Got this bigger for $250 craiglist. I learned after the fact that 44 degrees is too warm for beer. I checked out the spec on playing with the thermostat to get it colder, and that's currently a trial and error thing but seems to be getting colder. I'm pretty sure the foam is a result from the temp.
I also have a pressure problem, the line keeps bending real bad at the regulator going to the tap, I believe because there isn't enough slack, maybe a 2 foot line. In process of playing with it, I think I let the regulator sit with too much pressure and buggered it out. I currently have a new tap/reg/pressure line/ and spout on order. With that line clamped like it was, I think the regularly sat around 60 psi (enough for the relief to start hissing) for about an hour before I noticed. Also at one point before I leaned better let the co2 sit on its side for a day or so. Now no matter what pressure settings I use, it's letting all the tank pressure through at same time, think any or all of the above would bug out my regulator?
