So Dave, I'm kind of like that. I'm 82 y/o and volunteer at the local senior center. I do their sound. I'm in the process of upgrading their sound system. I got an equipment rack with a new amp, grouping a lot of the existing stuff that I'm also installing like secondary amp for, a graphic equalizer and DC player and plenty of input/out plugs and jacks. I'm also going to label everything so that others could use it. (So far, no ones offered) ha ha. I.m used to being the first one there and the last one to leave.

Throughout the 90s, I shot a lot of video on regular 8mm and Hi8 tape. Among the tapes there were a few of those SONY "Professional Grade" Hi8 cassettes. Many years later, when I was digitizing all of my analog tapes, I assumed that the Professional cassettes would have retained the best image quality and would have the least amount of deterioration due to age. I was surprised to see that they had the worst image quality and drop outs. All tapes consumer and "professional", were recorded using the same Sony camcorder and stored together under the same exact conditions.

[@12voltvids]

Had the same experience. Those pro x tapes had far higher dropout issues vlogged heads more often and just were shit. When new they did perform better but they sure didn't hold up well.

[@alisharifian535]

I think it is from the same era as the first generation Playstation. The silver prints,PCB copper trace layouts,geometry etc.. are very similar.

[@alisharifian535]

Plus lots of Sony ICs🙂

[@CanizaM]

Didn't you review some SMD tweezers not long ago? Seems like the perfect time to test them out!

[@12voltvids]

They are not good for high density board like this. No room to get them in.

[@antichicmusic]

1 & 4 is s-video from deck 1 (player only) my guess. Geees, thanks to youre videos I went through a xmas holiday refurb session and successfully recapped and repaired my nikon and Kyocera KX-H1E camcorders, thanks. When you opened up this and revealed the shear amount of caps, I was like, get out of here. Some of my boards were dry, but when I had them on for testing for hours, I noticed some of the caps sweating over the next days. And that fishy smell when, any cap I took out was wet underneath. I would'nt touch this with a stick. Well done on the minimal invasive repair!

[@gavincurtis]

It's like a nightmare.... pinch yourself really hard to wake up.

[@12voltvids]

That was 4 + hours on the bench to count all the caps and get the caps I did change done. It looks good and as i mentioned if it was mine I would just use it till it drops but for anyone serious about archiving. Find a good digital 8 camera. Then at least it's only 20 to 25 years old and has no smd caps I it.

[@terrym1065]

I started laughing when I saw the cap count on the first board...knew right then this was probably a no go. I bet the owner decides to use as is and I'd charge for the cap inventory as well.

[@12voltvids]

My EVS7000 was bad enough. It had about 50. No thanks.

[@mrpedrodrodriguezsr7628]

I can't say which deck and output you're using to capture video. My PC screen is too small to see a difference! Anyway, that machine looks great for archiving!

[@video99couk]

Absolutely agree with you. Unless someone really needs PCM audio recovery, a Digital8 camcorder is a much better prospect and can digitise the video at the same time. As for Panasonic, their DVCPRO professional machines are known for bad SM capacitors, sometimes hundreds of them and you just have to replace the whole lot.

@@12voltvids if you (not you Dave) were an organization in the day you'd probably be better to send it off to a proper factory or agent for an overhaul rather than in house it would sound more sensible

[@AstrosElectronicsLab]

First 38 seconds, and I already know the cap count is going to be at least over 1000.

[@12voltvids]

$1000? Yes minimum to change all the smd cape there are hundreds of them and they all cost me over 1.00 each when the weak dollar is factored in.

[@Dansbus1]

I recon 2 and 4 svideo because the detail in the darks is sharper you can see strands of hair. Considering the amount of caps that need changing and the age of the recording s just showed how good hi 8 was. Svhs was good in its day but if you put it up against Sonys offerings no contest especially when you add pcm

That was intended BTW. Effing camera always slips, the lock is getting tired.

[@Shadepariah]

it doesn't just cost more to fix than it's worth, it costs more to fix than it was EVER worth

[@12voltvids]

You got that right. Remember this stuff when new had a designed life cycle of 5 to 7 years! Thats all it is designed for as this stuff was designed for use in a TV station or small production facility and most of these places lease their equipment with a 5 year max replace cycle. So after 5 years of daily use it would be seemed to be worn out and would have been replaced. What happened is prople grab trhis old junk and sell it on Ebay and convince people that this old crap is better then more modern gear. Then a few youtubers and instragram influencers convince people that this old indistrial and pro gear is better than the more modern stuff, that it's built better. It really wasn't. In it's life cycle it was more maintainable as parts were available, and full boards were available for the service people. The individual boards were never designed to be component level repaired. Consumer gear was never designed to be repaired so you could not typically get a new board. i remember a fu*k up I did once. Never let me live that one down and actually made me pay for my fu*k up. Totally illegal but if I had challenged him the prick would have fired me. He was that type of person. I had a camera that came in that the board was broken. Customer was told it wasn't worth fixing, but customer insisted and convinced me to fix it. I looked up the board in the service manual and got a part number. Hey it wasn't too bad it was only 110.00. I did the standard mark up and added labour and gave it to the customer Probably about 300.00 and a new camera was 1000.00. He said go ahead and I ordered the part. It was about a month on back order and when it arrived I was in total shock. It was a bare unpopulated board! Sony wouldn't accept it back so the owner took the cost off my pay cheque to teach me a lesson. I tell you I never 5 finger discounted the shop until that prick started picking my pocket. I ordered the part in the Swhich by this time were online. There were 2 part numbers for it, bare board and assembled board. Like why bother listing the bare board, as if anyone is going to remove all the parts off one and place them on the other. The fullly populated board was like 700.00, so no he didn't fix at that point, he took my original advice. What happened to original you might wonder? Had it on their boat and a wave came over and got it wet.

[@AstrosElectronicsLab]

When you said "these are through-holes", you mean "vias" that interconnect between the top, bottom and inner layers of the PCB. And, from memory, the groove or lip on the lower drum assembly is called a rabbit.

[@12voltvids]

Via hole thru hole same thing. They interconnect internal board layers, and top and bottom. If I said via hole i would lose 95% viewers.

[@CycloneCordVHS]

Replace ALL the caps? It's like when the property manager asks you to replace all the lights in all the parking garages.

[@12voltvids]

When i was 15 I had a summer job with a family friend who ran a fluorescent lighting contract company and my job was just that. We went into commercial budings at night and replaced every lamp. Hundreds of them a night. The owner and brother in-law were the 2 electricians that did ballast replacements if the ballast was done. Owner had a few sons around my age and so did his brother in-law. They swapped lamps every 3 years in buildings. The theory was fluorescent bulbs by 30 000 hours operating had lost 50% lumans but still draw same power so they were replaced. Of course they were running 24/7 in office buildings and parkades. Had to do it in the evening after the business was closed. We typically went it at 6pm and left 11pm. The other hours loading up the truck and smashing all those old bulbs in the dumpster out back. Mercury into the environment? Back in 77 or 8 when I did this I didn't care. I wanted money to buy gas for my dirt bike that I rode all day with my friends out on that beach I showed in the drone video. Me and my buds uses to piss off all the residents with our 2 strokes running up and down the beach.

This one is hard, take into account the smudgy shitty youtube compression. Ok here's my bet 1 and 4 composite and 2 and 3 s-video. Impossible to know wich deck but i'll say 1 and 4 left deck and 2 and 3 right deck.

Ok so you picked 3 and 4 and you are correct. 3 and 4 were done with the same cable. 1 and 2 the other one. Which was S and which was composite? Then identify the machines? Lol.

@@12voltvids Definitely. There are losses from the tapes itself and also from the capture chain. It would probably a bit easier when viewed on a CRT directly without digitizing, deinterlacing, scaling and compression.

[@georgejennings9959]

You also have to consider if the ESR is rising (into the orange territory) and you already have many failed ones in the device then how many years will a partial recap give you before the others fail. So you kinda have to have an all or nothing mentality, or I guess seriously ask if theres something else you could use instead of this device. Just replacing outright bad caps is no guarantee either that it will work fine. But recapping will delay the inevitable, kinda like exercise does for the body, but again its best to identify critical irreplaceable equipment you value most and go all in. And none of those cheap 1000 or 2000 hour caps unless you enjoy repeating this every 1000 or 2000 hours. 😂🧐😵‍💫😵‍💫😵‍💫

[@12voltvids]

You never know how long any of this old stuff is going to last. Spending 1000+ to recap this unit, and that only would cover the SMD caps is no guarantee it will last 30 more years. A chip could pop, the FG sensor on a motor could fail. Any number of things could go south. Its one thing recapping an old stereo that has a few dozen caps in it, but to replace hundreds of them is just foolish unless you like throwing good money after bad. Plenty of better options for digitizing old hi8 tapes. A recent vintage digital8 camera with analog playback is the way to go. First of all no bad caps.

[@georgejennings9959]

I've *partially* recapped many vintage synths and mixers in my studio when there were too many worth the time. I've fully recapped but only on gear where they're all headed to red zone, and more expensive or personally valuable equipment. This has pretty much kept me free and clear of problems. Usually it's the mechanical things that start to show signs of failure, tact switches, encoders, fader pots. The blades of fans collect a lot of dust and help spread the dust around. I've had fans fail on computer PSUs, and can't help but wonder if it was the dust.

[@12voltvids]

I hear you. It's one thing if it's your own machine and you are just looking for a project to spend a few months on. I do know someone that does just that. He is an old ham operator i have known for about 40 years. He spends months recapping and calibrating old tube and SS tranaceivers as a labour or love but he is also long retired and has nothing else to do. He talks on his ham radio and when he isn't talking he is changing parts on old radios he picks up. Some take him a month or 2.
