Hi All....

Well I'm past my battery problem, The Ni-Cd was the way to go for this S-5 setup Thanks Ron!

Now onto a new issue...

Initially at the beginning of every song played on any CD, The speakers produced a sound as if a needle was just put down on a record at the begiining of a song.

It sounds like a flutter or wind noise.

After lubing everthing up, cleaning the CD players Lense, and allowing it to play on a Random setting for many hours, that sound has almost completely gone away but is still faintly there.

In addition, when the juke is at idle, with no Cd loaded, I can still fainly hear a flutter/wind noise coming out of the speakers.

Removing the Amp's left and right input jacks from the CD player have no effect....

I checked all the usual grounds etc....

Is this a sign that this Amp needs a rebuild?

If it does, Can I buy a cap and resistor kit like I am able to buy for my many 1950's Seeburgs?

Is there anyone local that rebuilds these?

Thanks in advance for all your help...

Jeff Pluchino

Hi Jeff,
It would be my guess, that you have a noisy transistor ( or IC) in that amp. I think that "RockOla" still repairs those--if not, then the tech who works there does it "on the side"--call them , ask for "Tech Help" and they should know---- Ron Rich

Thanks for the info Ron, I'm actually refurbishing 2 Rockola's (Back and Orange) as we speak and I was planning on calling Jorge early next week with my laundry list for both boxes So I guess I'll be sending this out to them as well...
