The End of the Road...

After working on Player pianos for over 25 years both part time and full time, I have decided to close the business. I have built the Bergytone pumps for over 8 years, and now there is just not enough orders coming in to keep it going.

Thank you to all of my loyal customers who have purchased and used my products through the years... I appreciate your support.


I will continue to provide support to those of you that have purchased my products, but I no longer am taking orders for Bergytone vacuum pumps.

I will be supplying my BT-003 speed controllers to those of you that want to make your own vacuum pump until all of my parts are used up. I have enough parts to continue to make these until late 2018.  I will also include an 11 page  instruction manual complete with dozens of photos showing you how to make your own vacuum box. This DIY manual has details on where to buy the parts needed to make the complete box. Read about it here

The current price of the speed controller with the DIY plans is $75. Send me an email if you are interested: bergytone@yahoo.com


I am keeping my “junkyard” open, as I’m looking to now to sell off many of the parts I have in my shop. I will be keeping my piano servicing and repair tools just in case I decide to get back into this at a later date. But many of the used parts I will be getting rid of, so be sure to look over my junkyard page.


Thanks again... And keep the music rolling!

If you need to contact me regarding product previously purchased, send an email to:

If you would like to order one of my speed controllers with the DIY pump instructions, send me an email and I’ll get one out to you.
