Alternative air pumps for ET2

I wouldn't worry about screwing up the arm itself, Alun. I think the problem with the Wisa was too little pressure rather than too much, but it was a long time ago :-)

Hello Alun , I'm using now the Japanese Takatsuki SPP-GA 15 , which has about 4 PSI , this is a very low noise pump,which operates here in the listening room , an alternative is the German WISA 340 Seaworld pump , which delivers about 7 PSI , but is too noisy to left in the room .But both pumps operate very good with my ET2 arm ,mounted on a Sphinx PJ 6 TT base and Dynavector Te Kaitora cartridge.I saw on the internet that the Japanese brand has an office in the US.(www.takatsuki.co.jp/english.

I use both a Wisa pump and the stock ET pump in tandem and run it into a homemade surge tank(a five gallon plastic gas can with aquarium stuffing inside). From there i use an inline filter to my 2.5. Sounds great and have had no problems with it. I keep both air pumps under a table in the corner of my listening room and after a while you become conditioned to the low droning of the pumps,no big shakes.
