I have been offered 4 of these for £200, as new condition.
Is this a decent 2nd hand price?
Cheers

Seems like a fair price, Mr Ed (on here) had some for sale, are they the ones with rotating gobos, as they can get a bit more money second hand.

£50 each is the usually price for working second hand vr8s...
i have bought 8 in the last few weeks and paid that amount
they are old but still bright and produce a nice effect ------------- Produce a killer sound. Take no prisoners. |

These aren't even 6 months old apparently.
I'm happy with the price.
And it seems that if i need to sell them on at any point, i should get my money back.
Bonus.!
 Cheers guys.

I remember buying a quantity of the VR8-R's back when they first came out and they were huge money! How times change. Still a very good unit. Some people report reliability problems, but I've never experienced any and that's using them heavily on the road. Clients like them just as much for their looks as the light they produce..

I should say I've very rarely seen the VR8-R's on the second hand market (ebay etc) - it's always the standard non-rotating version. I seem to remember their being a big price difference between the to when they first came out. Dan ------------- Dan Gruner Director Loud Audio Ltd.

yeah, 50quid a head is good, especially if they come with lamps without too much useage.... the vr8r's sell for roughly 100 a head as they are rare, and imo much much better.love these scans, their 4head standalone programs are really really good!!

Well, 3rd hand information is never right.!
They were a couple of years old, sat in an installation with no use for the last 6 months.
"They were starting to look out of place" the owner told me.
All working, 2 are spotless, new mirrors, lamps. The other two are really grubby, smoke stained and retaining pin housing has cracked on the base of one casing unit, but a bit of super glue and a clean up and they are alright now, new mirrors on both also.
Internals are quite clean, i put the 4 together and left them running their programme last night, down the bottom of the garden to a bit of S club 7.............
 Love em.
Well worth the money.
Cheers Guys

 Anyway, one stepper motor not working on the tilt, seems to be jamming. Tried to get the mirror off to open it up and see why......one broken mirror.! With my clumsy thick fingers, i also managed to knock a couple of pins of the IC's when i was checking the board for any problems.  So now i need a new mirror, a stepper motor - (abstract want £37.50 plus VAT just for this) and a new IC chip for pan tilt.... Looks like i'm going to have to make do with 3 for the time being! |

The chip you mean, is it the main ic programme chip or just the stepper motor chip. These are called darlington transistor arrays(???) Ive got a tube of them somewhere. If you send me the number on (ULN.... i think) them ill have a search.

Cheers. No more flea bay for me.!
Farnell have them in stock also, and some form of stepper motors that are a little cheaper than Abstract.
But my local Maplins "dont stock fings like that, specialist stuff innit! Be cheaper to frow it away an buy dis for fifty quid innit!"

Hi.
I have just purchased a stepper motor for my VR8 from Farnell that was posted on the forum.
Does anyone know the wiring from the original to the new Farnell one?
4 colours (red, orange, yellow, brown) are the same on both but old one has green & grey new one has black & white.
I have tried wiring them together & then swapping them but motor doesn't appear to do the right thing.
Can anyone help?
Darren.

The only thing i can suggest to find whigh wire does what is to draw 2 grids like this: 1 2 3 4 1 2 3 4 where the number represents the colour of the wires. meter out on resistance the different combinations and write the value in the relevent box, do this for both and it will give you an idea as to what is what. been a long time since i've done this but draw four coils in a square with the ends joined.... acctually, Its worth doing a search for stepper motor wiring and you'll find a few useful ideas explained much better... |

Hi, thanks for info.
I didnt have a good working motor to compare with so after finding the 2 +12V wires I just mixed the others up until I got something good out of it.
All seems ok.
Cheers
Darren.
