Did any of you guys ever see a HD 150 with a Phaser built in? I guess I didn't. I was out of the music store biz by the time these amps came out. Anyway, have one coming in soon with 2x12 for a tune up and the guy swears it has a phaser built in. I think maybe he's thinking trem. I am going to take it apart and get some good pics, I hope, since they seem to be kind of scarce around here. I personally have never worked on one so I will be interested in seeing the inside and how it compares to the 130's, of which I AM accustomed to. Mike.

DUH! Actually LOOKED at the schem and it was a phase shifter of sorts. Uses two LDR's and am guessing varies voltage to the system. HMMMM?
