Andy Mazur's 'Maztone Chief'

Andy was one of the first builders of the PP-36 and took the plunge even before I had finalised the construction documents. Together, we ironed out a few bugs and made the PP-36 kit ready for prime time. Thanks, man! Smile

Rob Jansen's much modded PP-36

Rob's PP-36 starts with the regular PP-36 parts and turret boards, but he has added quite a few of his own touches (as the internal photo shows).

"I finally finished the amp, after much experimenting with the preamp. There is one more ECC83 for more gain and a cathode follower before the tone stack. And the power reducer pot has become a master volume. No audible hum or noise at 'normal' volumes. I had no trouble with noise or squeal, though I made separate earth
groups for preamp and poweramp, and made one star earthing point were they all come together. I connected the input connector earth directly to the chassis via a small cap. to kill radio frequencies. I agree with you this is not an amp for a novice builder. Specially not when you want to modify things.

"I shortened the chassis at both sides, so I could keep the cabinet smaller in size. It was not so much trouble to cut off the chassis flanges, I spot-welded the corners of the chassis first so that the sides were stable.

Bobby's PP-36 head

"I made one of your PP-36 kits at Christmas last year and I absolutely
love it! I've attached a couple of pictures. I housed it in a 19-inch
steel rackmount box that I had lying around and put a steel wire mesh screen on the front."

Peter's PP-36 mini-stack
"Here's a photo of my happy 36 watter and its 15in Weber blue dog speaker. I used 12AU7s in preamp and phase inverter to clean it up a bit. Works nice with my magnetic pickup acoustic too and plenty loud. 12 months and still on original tubes."
