Although there are no service manuals or reprints available which cover this player action, Stephen Kent Goodman has written an excellent treatise that covers the identification of the system. He also goes on to explain how to remove the stack and offers sound advice with regards to the rebuilding of the valves. To access the Eastonola web page, click on the link below

Removing the fallboard assembly, the name "Eastonola Minor" was decaled on the upper deck of the two-tiered stack; a stack of less common architecture than usually found (illus. 1).

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.
