Question

Hi

my name is Sam I'm 26 Years and Live in Adelaide South Australia. My Hobbie is archiving Used Recorded VHS and Betamax Video Tapes with Australian TV shows and Commercials. I am interested in Electronics particularly Old CRT Colour TVs and VCRs.

I was wondering if anyone on this forum or someone they might know who is working and Retired ex Electrician who used to work on CRT TV or VCR Repair in a Electrical Repair shop or Rental Repair dept like eg Radio Rentals, Electronics Sales and Rentals, Ernsmiths, Thorn EMI, Canberra TV or Tandy's The Repair Shop.

I would love to learn about fixing Electronics and Meeting you. Been ringing around to find places to source TVs and VCRs. Have quite a List of Places.

Get in contact with me

I don't have a switcher as such, but I am sure that somewhere I have some 16x16 crosspoint video switcher ICs I got as samples years ago if that is of interest.  I fyou had asked about 15 years ago I was pulling out the old video distribution system from a university and turfed several 16x16 video switches... I didn't want to chuck 'em but even my giant pile of crap couldn't handle any more

@AskJacobSounds like it. I will get back to you on that. How Many do you have from the Uni? Just looking for one. I will talk to my friend who is into Hobbie Electronics "Emmanuel" he collects a lot of CRT TVs, TV Cameras and more. also volunteers for Channel 44 Adelaide's Community TV station and works for Channel 7 here is Adelaide

@Limorange @AskJacob already have E Waste, Skip, Hard Rubbish, Rubbish Removal and Scrap Metal Places in Adelaide Looking out for me. But if you can help that would be great

@AskJacob My Friend asked is the Video Switcher it Analogue? if it's a SDI it won't work with my set up

I don't have any of the old gear left. It was all analogue, made in australia too with plug in cards for multiple channels. I do have some of the lovely chunky illuminated switches from the panels, but everything else went to e-waste.

All I have now is some Maxim sample integrated circuits - which are a long way off from a complete unit!

I'm happy to see there is still some people out there who want that kind of stuff. If I come across stuff like it again I will try and connect people to it before it becomes e-waste...

Prior to Covid I had 240 VHS tapes with over 350 taped movies (including adverts) dating back to the early 80's.  Basically watched a movie every night and ditched the tapes after.  During the credits of Zulu Dawn, literally the last movie, the the video recorder stopped playing and on ejecting, the tape was chewed up.  Tried a few more of the tapes I'd watched that week (but hadn't binned) and same happened.  Ditched the video recorder and replaced with one of the dual VHS/DVD players I've got.  Then I watched 50 odd of the purchased movies on VHS (that I've since bought DVD's of) and ditched them.

Yet to watch the remaining 40 odd purchased VHS movies and have hung onto a few VHS taped movies and some Rage specials, including the 1991 Hotest 100 when Nirvana knocked off Joy Division (an absolute travesty).

This reminds me, that I need to get one of my footy premierships and a mate winning the car on the Wheel of Fortune from the early 90's copied to DVD.

Still have a laminated wood TV in the games room, as there's nothing like watching the "Sheets of San Francisco" and other classic VHS porn movies on an old box, while smoking cigars, sipping on Scotch and playing poker!

Generally speaking your hobby is primarily analog as you probably already know, but crossing over to digital in the early 90s, and that was before everyone documented everything on the internet ...That switcher for example like alot of my equipment is best reversed engineered for 2 reasons,  one being its age, history, and possible old filter caps, And the other is to gain an electrical understanding of it far beyond a manual even if you could find one (The Fluke 9010 on my bench at the moment comes to mind, horrible beast to learn)...Anyway my guess without looking at it, and being analog be nature, it probably needs a bias resistance load of some kind on the out side, to draw signal, That was actually how we linked test gear together back in the day...Crts are a little more forgiving under these conditions, and are quite well documented (parts are a big deal anymore) but what you probibally won't hear is...MIT radiation laboratory (#23, I believe) is a encyclopedia set of WW2 post war secrets dealing with a whole host of information on the subject, although it does require a deep rooted understanding in the physics and math especially as it relates to valve style power supply technology.
