Is this cable advertised as being CCA or pretend to be a regular copper one? Is there a way to spot CCA network cables without cutting it open?

Is it flux or could it be something else? I always wondered why some old PCB boards becomes sticky when you use some isopropanol on it, and thought it could be some protection against oxydation or maybe flame retardant?

Could it be that the glue covering R39 has become conductive, lowering the resistance ?

What an extensive review! 👍 But for me, a fish sauce should be only, as the name implies, made of fish, with only salt and water. So any variant with added sugar, MSG or whatever else is a BIG NO-NO ! There's already too much hidden sugar added in everything where it shouldn't and is bad for health.

I was in contact with www.sofh.it and started to talk about refurbishing a QIC drive's captsan, and he was ok to try if i could send him a capstan and dimensions of rubber part. But i had other priorities to deal with and the drive has remain stored as is still then. But certainly something to try.

Capstan/roller refurbishing is also a problem for audio/video tape devices. There are some people out there able to recreate ones with new rubber, casted (not glued or force inserted) on metal axle, adjusted and balanced with a lathe with tight tolerance...

I enjoyed this final episode so much! Thanks to Ben and all the crew 🙏 The animations in end credits are epic, i would love to know how it was produced. Must be so exciting and rewarding to work on such a project, and to have the means to carry it out. I dream one day i could work on such a project.

Several details made me wonder if this episode was shot in film rather than digital? Noise in the last still picture, white dust like spots (like if it was dust on the negative film), the look of rolling end credits (a little fuzzy with saturated luma)... So really film or post effects?

Would you have more information about the nastyness of these moulds? I know that in the nature/environment some can be dangerous for our health, but until now i've not found any document about what kind of mould can grow on magnetic tapes, and if they are dangerous or not for humans.

kinap35.bsky.social @kinap35.bsky.social · 13/02/2025

Does your contact have some documented information about this cristallized formaldehyde assumption? I've not been able to find informations about potential mold toxicity/health risks. Baking could kill living mold, but unlikely to destroy their spores that can dessiminate everywhere in the air.

kinap35.bsky.social @kinap35.bsky.social · 13/02/2025

UCA tapes not KCA 🤦🏻‍♂️ Here some white casing small tapes (including some Sony and JVC alignment tapes, which is quite unfortunate) with wax crayon smell and low to very low RF level. 4 JVC alignment tapes (probably using originally Sony manufactured tapes) left fine white powder residue when cleaned.

kinap35.bsky.social @kinap35.bsky.social · 13/02/2025

So i wonder if this could be a combined effect of some released chemical exposed to humidity and then agregated and cristallized when stored in a more dry environment. And i don't know if the same formulation of tape binder used in some white KCS tapes could have been used in large KCA ones.

100

kinap35.bsky.social @kinap35.bsky.social · 13/02/2025

I've had some Sony KCS tapes in white plastic casing (also sold under other brands like Fuji) and some, despite not having mold, released a fine white powder when cleaned in professionnal cleaning machines. These tapes also smell like wax crayons, and do often exhibit a strong loss of RF level.

kinap35.bsky.social @kinap35.bsky.social · 13/02/2025

I never heard of crystalized formaldehyde before, and this mostly looks like mold. But there are also some kind of cristal looking things on the central plastic hub on the before picture, and apparently no more after baking. Strange...

Great video, thanks to @techconnectify.bsky.social too! I always wondered about that without taking time to scientifically compare those options. Now i know! I wonder if the use of those all-in-one tabs containing too much detergent could be the reason of some damaged glass items? It's not limestone

Side by side comparison of glassware items: damaged after dishwasher cleaning vs undamaged (while also dishwasher cleaned).

This guy is refurbishing video head for an Akai VT-100 VTR by replacing broken ferrites with U-Matic ones, rewinding new coils on them, glue them back on holders, and putting back the heads on the drum. Impressive! www.youtube.com/watch?v=mNnn... Impressive, even if VT is a low quality format.

Quite a few should work great on nowdays system using the great VueScan software. I've read that it works also with SCSI -> FireWire -> Thunderbolt adapters on macOS, and maybe also with PCIe -> Thunderbolt (untested). Otherwise exists also for Windows and Ubuntu.

Nice! Is it really 1956? I'm surprised to see at 8'10 a display with animated video saying "soup contains 14 garden vegetables". I wonder what technology was used at that time. 🤔

kinap35.bsky.social @kinap35.bsky.social · 23/11/2024

Using/replacing your wiping fork during a copy? Doesn't it induce tape tension and speed variations detrimental to optimal playback quality? Out of curiosity, what cleaning product were you using?

100

kinap35.bsky.social @kinap35.bsky.social · 23/11/2024

Yeah, that's what i feared. Probably no other way that manually using various intermediate versions to incrementally upgrade the file format... Oh dear! 🫠

kinap35.bsky.social @kinap35.bsky.social · 23/11/2024

Another thought: dissemination of spores during mechanical cleaning process and/or tape playback. It could be usefull to find a way to effectively decontaminate devices (cleaner, tape players, disk drives...), cassette or disks cases, and even surrouding areas. Mold is a vast topic of discussion! 🫠

kinap35.bsky.social @kinap35.bsky.social · 23/11/2024

So i wonder if cyclomethicone could have the same undesirable side effect, and if so, i would be reluctant to put anywhere close from electronic circuit, but also close or worse in direct contact with sensitive and micron precision level parts like tape path, drum and magnetics heads...

kinap35.bsky.social @kinap35.bsky.social · 23/11/2024

Additional morning thought: i read on tape recorders restauration forums that using silicone based lubricant is not recommended in electrical/electronical devices, since silicone migrates very easily, and can cause electrical problems because of polimerization into hard brittle conductive material.

kinap35.bsky.social @kinap35.bsky.social · 22/11/2024

Surprisingly, since they are tons of magnetic medias stored since decades, it doesn't seem there is a commonly adopted advanced technique, but only some individual and more or less secret recipes...

kinap35.bsky.social @kinap35.bsky.social · 22/11/2024

Cyclomethicone seems to be some silicone blend. What effect is it supposed to have on mold? It seems that some chemicals, like peroxyde hydrogen could kill spores by breaking down proteins and DNA. But is it safe for tapes? UV could also kill spores, but is it safe for tapes?

010

kinap35.bsky.social @kinap35.bsky.social · 22/11/2024

To my knowledge, INA (French Audiovisual National Institute) in charge of preserving TV and radio programs, do not use anything else than these RTI cleaning devices, and baking if necessary (in case of sticky shed syndrome). And so do i. But i've always wondered if better techniques could exist.

020

kinap35.bsky.social @kinap35.bsky.social · 22/11/2024

Some also prevently bakes tapes before cleaning, claiming that it will kill mold, but if it can probably dry and kill grown mold, it probably doesn't kill spores (temperature too low). And with or without baking, cleaning will certainly release a lot of spores in the device and surrounding air.

000

kinap35.bsky.social @kinap35.bsky.social · 22/11/2024

Never heard about using cyclomethicone in tape archive cleaning. Usually tapes are simply simply cleaned (dry clean) in a device like these ones. It's unclear if mold growing on tapes can be dangerous for health, or if special care should be taken (ventilation or respiratory device?).

Great info indeed. Thanks! By the way: i recently discovered that you can't open old/early Word 1 or Excel 3 files with todays Word and Excel. This is true for other applications too. Any recommanded way to convert vintage files from old mac disks/archives to be able to use them outside emulators?

Could it be that some badly manufactured 0 ohm resistors could degrade other time?

100

kinap35.bsky.social @kinap35.bsky.social · 23/06/2024

I repaired a device where faults were because 0 ohms resistors became resistive, up to MOhms or open circuit! They were under blobs of clear silicon so thought maybe some chemical reaction degraded them, but since other components under blobs were OK, and reading your post i'm unsure now... 🤨
