Did you ever fit a new laser optic unit to the Lambda as I suggested? My problems were the same as yours untill I did that.

Thanks for asking tubenut

I haven't even been able to get a new laser assembly over here so far.
Most prospects seem to be in Europe, and more particularly in Germany where they either don't speak English (often the case) and in a couple of instances also refused to do business with Americans. Most of my inquiries have been ignored. I am looking for a new one to purchase, but I suspect another issue as a simple back panel reset once in a while and cleaning the connector on the mechanism resolves the problem sometimes for up to 6 months at a stretch. Also unlike many units of this vintage this one does not have many hours on it. Right now it has worked fine for about 2 months.

I am probably just going to eventually buy something else to replace it, money is less of an issue than my limited time.

I will make very sure it does not have a Philips mech in it before I buy it.. My old Sony is twice as old and must have > 5K hours use on it and is still doing yeoman duty at a friend's house.

LOL

Kevin

This sounds very odd to me as most germans do speak english. Certainly companies can help english speaking customers. Compare that to the amount of americans speaking german They are sensitive for correctness though, call it etiquette if you want.

I have had a post in the Trading Post for months in which I offered 2 CDM9 mechanisms, one CDM 9/44 new in box and one used CDM 9/65. Some time ago I sent a CDM3 mechanism to the USA as a gentleman over there was searching for one of those rare CDMs. Better check the Trading post some more. I recently saw a member offering new CDM 9/44 but I am not sure in what section this post was. Anyhow, if you really want one you will find the post using our love-and-hate tool, the Search function.

About Sony mechs; I have not seen many Sony mechanisms living longer than CDM1/4/9. It must be a real old one you are referring to as the modern ones are chinese OEM mechanisms that shine in only one area: cost.

Grandata in the UK certainly speak English and they do sell CDM9/44 although it could well be the refurbished type. Not many original brand spanking new ones are around. I can buy a refurb type here in SA for about USD60.00. There is a dutch company selling same for 25 Euro but can not remember their name. They speak English for sure. Google for CD9/44...
