Welcome to PhotonLexicon, Rick!
Knew you'd get around to joining us here sooner or later... :wink:
Guys - Rick is one of the distributors for the DT-40 scanners. But more to the point, he's the developer and distributor of the Alphalite software and hardware for laser shows.
Glad to see you here pal...
Adam
Greetings Rick! :D
Well hello Rick! Hows the weather up there?
Yep, he also developed PCLite many years ago and I was the proud owner of a kit that I put together. I think I still have the old PCLite software around here somewhere. It was pretty basic in what it could do, but was alot of fun to work with!Quote:

Hi Rick :)
You are so latecomer join here :wink:
Well I am very happy with the DT-40 pros.
They make a little more noise then the 30`s I had, but I like them.
Also the amps have to have a fan on them,
even when mounted to a very large heat sink they get very warm.
My other amps never got hot at all when mounted to the same heat sink.
From now on I will be using these in all projectors I build.
Some noise from the mount's heat sink.The mount heat sink can create resonance.Quote:

Don't use fan resolve the hot of amps.
mounted a large heat sink or install the amps to the case housing better.
Because some amps parts must warm to stabilization.
I always adjust the amps after the scanner working 5-10min.
Sorry for my bad english. :shock:
Do you understand?
Yes I understand. I will not use fan. They are mounted on a very heacy and finned heatsink which is then mounted to the case.Quote:

Well as luck would have it, if I had any luck. The Y scanner amp went out on me tonight. I turned on the system and the leds lit up but no output to the Y galvo. I checked the galvo with the other amp and it works fine so it is the amp. DAM I am so mad I could rip someone's head off, well not really but I am pissed!! I guess I will have to see how Jian handles this, I just sent out an e-mail. If I have to ship it back to China I will NEVER NEVER buy a set of scanners from China again. It is just too darn frustrating to deal with. The last time I had to send something back to China it cost me $103 to get it there in 4 days Fedex and it was just 2 lbs ???? :evil: :evil: :evil: :evil:
I will let everyone know how this gets worked out just in case your ever in this situation. It just sucks :cry: :cry: :cry:
Fred,
Are you certain its getting signal from your dac? Did you try swapping the input cable? I'd be surprised if the amp was blown. Is it a DT-40pro amp or the original dt-40 amp? There's not a whole lot to that amp and I would be happy to look at it if you like.

Yes it is getting a siganal and I found the problem, The on board fuse was blown. I replaced it and it is up and running. I checked all wires and every thing is fine so I don`t know why it blew the fuse when I turned it on?? :?:Quote:
