Sony VO5850 with a bad video head can a different drum be shoe horned in and work? Let's find out.

Remember the U-matic last month with the open coil video head? It's mine now to experiment with, so lets hack away.

That microscope camera is such a great addition to these videos, you do excellent work👍

[@12voltvids]

I have a few, but since this one is battery powered I have been grabbing this new one first as the others all have to be plugged in.

[@m9ovich785]

Great Video Dave. Liked the Story about Your Father.. Pretty nice storage unit, Finished Walls, Power, Windows, LOL...

[@12voltvids]

It has a window, power is insulated and had heat so equipment won't freeze. I operated my video conversion business out of here when I was building the house 22 years ago.

My dad kept that receiver secret and never used it. Even though he was the sole earner he was NOT in charge of the money. Mom was, and she balanced that cheque book to the penny. Even though my dad had a good job, a longshoreman we never seemed to have any money to spare. Turned out he was looking after his little sister paying her bills ect when her dead beat alcoholic husband pretty much bankrupted her)After seeing first hand what alcohol can do it's no wonder I don't drink. Anyway he blew a bunch of cash, probably 500 bucks on this in 1969 and my mother had a fit. I remember when he bought it as I was with him, and I remember when she made him return it. It just never got returned. I have had it since the early 90's when I found it under the house, and did enjoy it for awhile, and I am hanging on to it as it has sentimental value, and well, It's a Macintosh. What can I say. The most sought after brand around. That's why I am not using it. I don't want to run up hours as it's all original.

The half loading could also be a self cleaning feature. I had a VHS that had a small felt pad that would wipe the head at certain loading positions

[@12voltvids]

They had not even dreamed of head cleaners at this point. The half load is for the tape counter. There js a separate control track reader head that reads the control track on ff and rew so the tape counter will work.

[@Johnrice-f4i]

@@12voltvids i thought I saw one in the video. It is at the 6 o'clock position. Small white round pad.or is that something else?

Tell me about it. Those R-R tapes in my locker however are good. That formulation didn't have 3S.

most heads are damaged in the sails ?

[@steve5090406]

Maybe an upper drum polishing session, would help those old drums.

[@12voltvids]

They are intended to be rough that allows air in to help move the tape.

[@Whakamescope]

yeah sticky shed is a bit like capacitors. some tapes does, while a lot don't even after decade of bad storage and get mouldy, but binder is still solid. all in all tapes seems more reliable than consumer recordable CD/DVD for exemple, and btw still in use for data archiving (LTO for exemple). and i would even say tapes are very likeky to retain content longtime more than flash memory in long term cold storage. do you know why umatic tend to show sometime "edge echo" on some tapes? i heard it was a frequent thing, but the reason seems a bit unclear.

[@12voltvids]

I have hundreds of cdr disks and dvd-r that were recorded over 25 years ago and they all play perfect. Yes there were garbage discs produced by companies like princo. Also sold by others namely D.I.S.C. (digital information storage corp) that self erased because princo were shit. I have dozens of gold kao discs and they are all still perfect. I got my first cd burner in 88 or 89. The first year they came out. Still have an original hp cdrw and its still usable and has files on it. Don't knock optical media from bad information and there is a ton. If stored away from light and heat and not physically damaged any good optical media will last a very long time. Unfortunately cheap crap discs that should never have been allowed to have been sold created headaches for some and then gave all the good brands a bad reputation. Its like saying a Lada is a bad car therefore all cars are bad. There were plenty of good discs and bad ones. BDR discs will last a lifetime because the data is stored in a metal layer that is physically burned. So will the MDisk DVD discs. Dye based well I have dvds over 25 years old that are fine today. How much longer will they last is anyone's guess. I copied them all at 12 years and will make a copy of the copy at some point. Thing is once on DVD you can copy that copy of a copy and it never degrades. Can't do that with analog tape.

[@12voltvids]

Umatic suffered from ringing on early machines. They got much better. The sp version had eliminated it.

[@crashbandicoot4everr]

I seem to remember you used distilled water on the NV-9200's audio/control head and that took care of it. Is the PV-1730 in that storage locker?

[@12voltvids]

1730 is there.

[@erikkennedy1271]

Dave, What's the most difficult, biggest pain in the butt repair you've performed on a VCR?

[@12voltvids]

I don't remember. Most VCRs are simple, because when they get too involved people just scrap them. Always have. PV1730 are always a headache. Thats why mine sits in the storage unit. Some day I might get on it again. They were a real piece of work. Direct drive motors for everything, tension feedback up the kazoo, and they were really nasty to work on. All those old ones were. JVC, lives up to their reputation, JUNK VERY CHEAP. Man I hated those with a passion.

[@mmichaelnowell1512]

Try some nu finish car wax on that spot let it dry polish it, then alcohol ! I did it and it worked believe or not !!!!!

[@mikecassap]

Dave just for shits and giggles you should try and have a go repairing the original head now that you got that microscope👍🇦🇺

[@12voltvids]

Too late, it's gone. I put it up on facebook and it went away within an hour.

[@Shadepariah]

@@12voltvids people want broken 3/4" heads that bad in 2024, eh?

[@12voltvids]

I put it up on Facebook and it was gone before I finished editing I just wanted rid of it. If I don't have a use for it I am getting rid of stuff

[@richiereyn]

Those Ampex tapes were crap. I have loads that went bad, some were brand new and never used. BASF chrome tapes were another disaster, but with those it wasn't sticky shed, it was leeching white powder all over the tape path. 3M tapes were variable, though I never had trouble with the color plus range. Old Sony tapes fro the 70's occasionally suffer sticky shed, but the ones made since the 80's seem to hold up pretty well. I am amazed you can play an SP tape on that machine. Try that in a PAL low-band machine and it's totally unwatchable.

Apparently the head chips can be replaced and the protrusion can be set by eye saw this video awhile back. Is it the proper way no but it appears to work well enough. Whether it's worth the effort or not is another story. kzbin.info/www/bejne/nWGxnZiwat-pi68

[@12voltvids]

I have done it. Not worth the trouble. Would only be done for obsolete format where no replacement was available. Like for a IVC 1" B format.

[@livinlifetothefullest2750]

@@12voltvids pity the chips weren't available rather than the drum and chip BUT that's easy to say cos you've got to consider the surface of the drum is still usable before even replacing a chip THEN if you've go the patience to adjust the dihedhral ajustment IF you're lucky to have the bonus of a manual on hand to do that adjustment perfectly!
