A quick outline — I acquired (i.e. swapped it for some ads on my DJWORX site) a Vestax VRX-2000 cutter a few years ago directly from Vestax UK. After a brief inspection, it became clear that there were issues, the main one being the platter rubbing the chassis, and a few missing bits. So I put back in the box and left it alone.
Until last week that is, when I decided to sell it as is as a doer upper project. But my inquisitive nature got the better of me, as did my desire as a DJ to cut at least one piece of vinyl as a bucket list entry. And now having fixed the platter, replaced screws, bought a counterweight, and got the lead screw motor running, I've got a working VRX that cuts a deep and noise-free groove.
The problem is that no audio is being cut. The VU meters bounce happily, but nothing comes through. I believe that you're supposed to hear audio from the cutting head but there's nothing coming out of it. So somewhere between the meters and head there's an issue. Time to open it up I figured.
So this is the inside of a VRX-2000. It's clean, and after a cursory inspection nothing seems to be broken or burned out. I've tightened a few screws, and pushed home all connectors, but otherwise it all looks good.
But then I noticed something on the left hand side. There are screw holes in the chassis and a definite space for... something.
Below the space is a transformer. There's a connection, but it's not connected to anything, nor does there appear to be a place for it to connect to.
And then there are these spare leads. Labelled PWR, CN1 in, and CN2 out, they feel as if they should be connected to something.
I've been posting my progress on Instagram and on my Facebook page, and luckily some of my friends are former Vestax employees. They along with another guy have been very helpful, and we now believe that the preamp stage is missing, as in it has been there, but for some reason has been removed.
So I've come to the Lathe Trolls for help. I fully appreciate the lowly position the VRX-2000 holds in the scheme of things, but is there anyone out there with experience of the unit that may be able to shed further light? Perhaps there are former owners who have opened up their units for a dig around. Maybe some of you have photos of the insides that will allow me to identify if there is a missing part, or perhaps suggest another reason why the cutting head doesn't seem to receive audio. Perhaps there's even a unit in bits that I could grab the spare part from.
Bottom line - it's a massive shame that a device such as this is so close to working. I'm learning so much about the medium that I've bought for 3+ decades, and would love to see this machine making music all over again.
Any help anyone can offer is gratefully received. I'll be writing up the whole experience for my site and will happily credit and give much coverage to anyone who can help me.
Many thanks in advance.
