A needle change will NOT affect stereo/mono operation in a stereo machine. The "audio (mono and stereo)" and "video" at the stylus are in the form of modulated RF carriers. The circuits in a mono unit simply ignore/ are unable to do anything with the stereo carrier where as a stereo player has the extra circuits for the stereo carrier. It's completely analog though so dude's analog fetish is not being corrupted in stereo models.

Stereo discs are in blue caddies, monophonic discs are in white caddies, and interactive discs (which play as a jumble of random scenes without an interactive player) come in black caddies. Mono and stereo disks will play on any type of CED player the same way mono or stereo FM radio will play on any type of FM radio.

That is how these things work, I was racking my brain for a minute wondering why someone else did it. I tried finding that old thread again. I am pretty sure stereo/mono wasn't what they were after just trying to use what they had around or could easily get.

Possibly using the stylus from in early sgt/sjt in a later model or the other way around.

Ya know what would be awesome Slatton??

Do you have THE GOONIES on VD?? (I cant find that either on its official VHS (All I can find of it is 'digitally processed' copies of 11474)) The videodisc IS STRAIGHT ANALOGUE....


If so would ya try please try making a copy for me onto VHS? (SP mode)

I don't have Goonies, or a working VHS.

I have had some friends ask me about making VHS copies of some of my early LD's though, bot no ones wanted to set me up with a VCR and clean tape "Yeah, I'll let you borrow mine.. next week... Ah I'm not that worried about it anymore".

Thing is too, these friends are local, so if I did they can prove to me that they own some copy of the movie to help stay clear of those pirate lines.

Some of my early LD's that get requested a lot are,

All analogue,
Back to the Future
Revenge of the Nerds (original mono track)
Revenge of the Nerds II
Scarface
Butch Cassidy and the Sundance Kid
Aliens
Indiana Jones - Raiders, Temple of Doom
Karate Kid 1 and 2
Police Squad, More Police Squad, Naked Gun
Lawnmower Man

Damn, this list is getting too long, you get the idea.

I have some others as well and some later LD's that are still preferred over VHS counterparts.

I love your list!!
