hitachi ps-48 no power

Post by joeboemoe » 15 Jan 2019 18:38

Hi, just tried to put my ps-48 to work again, but when I lift the tonearm, no action!
Is there a fuse that I need to change or what could be the problem?

Regards, Joe

Get a multi-meter, and check the wiring. switches, etc. This will save a lot of guesswork and frustration.
Start from the plug.
You might find that some contacts need cleaning.

Cheers,
Alec

Hello Joe, welcome to vinylengine.

There are two fuses on the main PCB that you can check - but I would rather assume, that the switch, which starts the turntable, is defective (probably it has oxidized contacts).
Another possibility would be, that the Rifa radio interference suppression capacitor on the main PCB is broken (they are known for causing problems after so many years).
These are the points, that I would check first (it is advisable, to have a multimeter for that).

Thanks a lot! It was the oxidized switch!
My turntable now works great again!

I'm glad to hear, that your turntable is working again! =D>
Keep it spinning... . :D

P.S.:
I would recommend to change the old radio interference suppression capacitor from the brand Rifa. They tend to pass away with a bang and a lot of awful smelling smoke (that once was the case at one of my Hitachi PS-38 :().
I prophylactically replaced all Rifa capacitors on my turntables (capacitors, which have the X2 standard, from the brand Wima are a good alternative, for example).

Regards.
