Re: Nikko Beta 30 pre amp

Does any good Samaritan have a schematic for this pre-amp. I have a customer who is emotionally attached to this machine for 30 years, and would like to fix it for him.

Highly appreciate any help on this one....Thanks a lot

Re: Nikko Beta 30 pre amp

I would also need someone to give some help about finding the service manual of this Nikko Beta 30 preamp. Why is it so difficult to find?

If anyone has the manual for the above I would love to obtain a copy to figure out all the buttons... ??? any help in that regard much appreciated. cheers. Bill.

Re: beta 30 manual

Let me help you to figure out this little baby.
From the middle:
-SoundProcessor : This is if you would have some type of processor attatched to it, like Time Delay, EQs or a Expander. Having it off (Out) allows to bypass the processor input
-Selector: This is where you select witch input you want to hear. This bad boy is able to output on two different lines (like if you would have two different set of amp and speaker on it). So you can play Aux on you main speaker and Record on the other.
From the bottom row :
-Subsonic fil : This function restrain certains frequencies that could damage your speakers
-Mode : Stereo or Mono, pretty straight foward there :P
-Catridge MM\MC : This function is for selecting the type of cartrigde (needle) that your phono uses, MC = Moving Coil and MM Moving Magnet. If you are really interested in that, take a look on Wikipedia they have alot information on this subject.
-Tape Mon : This is if you would have a Tape connected to the preamp and would like to record
I guess that the rest you already figured out :P
