Always a three-tier stack with vertical valves. (The Autotone had primary valves; the Playotone did not.) All Hardman player actions used a pneumatic tracking device. It was very simple, and for that reason may be the best clue to identification, since the pneumatic stack is in general, very ordinary. Only one tracking ear was used on the largest percentage. (The use of two tracking ears was only on very late models.) The single tracking ear was to read the left paper edge only. Opening the valve of this tracking ear allowed air to enter a small pneumatic on the left side of the spool box, and as the pneumatic opened up when it had more atmospheric air than the fixed bleed supply could overcome, the pressure of the music roll took up the slack by pushing the paper to the right, thus closing the valve port; as vacuum built up inside this small pneumatic again, it drove the paper back against the tracking ear, repeating the cycle.
Very small foot pumps were used, with a single reservoir in front above the compact folding pedals. The motor governor and cut-out box were not attached to the pumps. A six-point double pneumatic motor was used.
Since "Player-Care" is an internet business, I prefer that we correspond via E-Mail (click here to fill out the 'Request Form'). However, if I'm not in the middle of some other activity, you can reach me at 732-840-8787. But please understand that during the hours from 8AM-5PM EST (Mon-Sat), I'm generally quite busy. So, I probably won't answer the phone. If you get the answering machine, please leave a detailed message stating the reason for your call. Also, repeat your name and phone number clearly and distinctly. By necessity, I prioritize everything in my life. And, if you call and just leave your name and number, and ask me to call you back, it might be a day or two before I return your call. Why? Because I don't know why you want me to call and I might not be prepared to assist you in an effective and efficient manner. If you leave me an E-Mail address (which I prefer), spell it out phonetically. The more you do to help me, the more I can help you in return. Don't rush. You have four minutes to record your message.
