This is as close as I could get. http://www.musicparts.com/products.asp?Company=Acoustic
The 860 is probably very close match.

I will buy a Technics se a900s amplifier, but


I think you are saying you want to connect the amp and use it's vu meters but not connect it to speakers?
Presumably you are already well catered for in the matter of amplification but lacking good vu meters?

There is a fair amount of information about this premium amp online including operating and service manuals that can provide a better answer than I can.

One note of caution; it is generally bad practice to operate a power amplifier without a load at the output and it might damage the amplifier. If it is desired to operate it without speakers providing the load, dummy loads are available.

I suggest you have a look through ebay or Amazon where you might find digital or analogue vu meters at a reasonable cost or alternatively I believe computer software could turn your laptop into vu meters.

Need the radio code


well, I don't know, the dealer has all of that info, but if your lucky you can pull the old radio and maybe a previous owner or mechanic was thoughtful enough to write the code on top. Locate the two springloaded tabs on the left and right sides of the face, push them in gently with a knife or flat screwdriver and use them to pull the radio out. Good luck.

Replacement parts for Pyle power amp PT-2000


VU meters are generally illuminated by small bulbs at the back of them. It's unlikely to be a powerfull bulb perhaps 12 volts perhaps around 200ma at the most. Most electrical shops should sell something that should suffice. It could be an LED though!

When i record my vocals its only in one channel why!


Hi,

It seems that the recording input source is provided as "Line In" whereas you need to select the "Mic In".
This is because the "Line In" is a stereo input and expects input for both right and left channels whereas the "Mic In" input is a mono input which is the same as our default condensed mic device is.

By the way, you would be able to see the graphic VU meters while recording, weren't they displayed that the recording is done only for one channel ?
Always use VU meters for checking the levels for recording, they are available with almost all recording softwares.

Hope this helps.

Thanks

HELLO I HAVE 670ZX WITH OLD STYLE VU METERS. EVERYTHING WORKS GREAT EXCEPT THE VU METERS ARE SLOWING TO A STOP ALMOST. THERE IS OUTPUT ON BOTH CHANNELS AND IT SOUNDS GREAT BUT...........METERS ARE FAILING.


hi, a vu meters is a coil with a magnetic field, if it is slowing to stop, probably the coil is to old and you have to calibrate it (specialist) the best for you: replace the vu meter.
