Eminent Technology tonearm ET--2


I am finding that my pumps may not provide enough air pressure for the tonearm.

Is it possible dust builds up in the tonearm manifold and one needs to blow dust out?  How do you do it?

Is it possible the inline filter is plugged.  I use a Motor Guard Corp. D-13.  How would I tell if plugged and can I clean?

Should I buy a new pump?  I have one called Takatsuki SPP-6GA and one WISA D.B.G.M. Audio Pump.  Is one preferred over the other?  What is the airflow in each?

How do I measure the airflow coming out of the pump?

There is a lot of info on the ET2 in these archives and a few aficionados as well. Do a search. Far as I can recall, all of the issues you mention may pertain.

Use Wiser pump, it provides higher pressures. Acquarium pumps don't have high pressure value.

Get a in-line pressure gauge to show pressure from pump.
