Curious to see what others have done as far as modding their Datavideo TBC-1000's.

Wanted to share one I recently did.
Soldered input to VP-301 board
Soldered output to VP-301 board and placed adjacent to the input terminal on the front of the unit

Nice, looks great. Only thing i've done is with those cables you made me. Moved input and output to the back for potential rack mounting. Kinda wanna 3d scan and print new cases for these things so I can keep the original unmodded.

What do you guys keep the distribution amp for since the TBC-1000 does not process audio? Convenient audio routing? Is it a good idea to get rid of it and put the TBC inside a smaller case like the AVTtool? I can help with case design if I have the exact internal TBC PCB dimensions and connectors exact locations.

According to Diopter there's some components of the power supply on the dist board and you'd need to do more work to remove it. Can be removed if needed. Just mostly not worth the extra work.

You can remove the amp, but you lose some caps, a diode, and a voltage regulator needed to power the video board.

I've been recording the different revisions as I come across them. Essentially you need 5, 8, or 12v going to the video board depending on what transistors are on your unit. From what I've seen, the video board components only need 5v and 3.3v to work. I don't care to make a new board for myself but if somebody wanted it, I could do it, but it would definitely take some time.

One of the members here already did the modification but kept the same metal case, He did a very good job. Something that I can do in less than an hour if I have the TBC-1000 assuming all components are ready.

No. Heat is not your friend. The case quality (plastic) and design (tiny) is likely why most green AVT-8710s (and even many black AVT-8710s) have failed over the years, why so few are now left. I tried to heatsink mod AVT-8710s in the past, but it didn't make a huge difference with the plastic case trapping the heat. The unit design sucked. Not just due to heat, but lack of power button, etc. The 1T-TBC "clones" were a bit better design, as were BV units. But both were still small for greatest longevity.

Internals differ, multiple TBC-1000 variants. I've considered created a new case, and probably will, but one thing at a time. It has to be a modular unit that allows for any of the card revisions. So all needs power boards (as needed), all I/O cabling options. Otherwise it'd never work. I may need to get with Diopter_Doctor, to help speed things along. But it's not a DIY kit, I/we'd have to buy a stock of at least 50 units (minimum order). To recoup costs, it won't be cheap, maybe $100. Odds of selling 50 for $100 is low (or rather slow, I have no doubt they'd sell eventually), hence why not high on my to-do list.

This is one of those things where big ideas aren't backed by dollars to make it happen. Sort of like Kickstarting a TBC. Not knowing what you don't know.

You can't remove it. You have to create a new power board. Also noting the mini brown sub-board is crap in certain units, also needs replacing. Again, a modular design is required, to account for at least 5 iterations.

Time and funds.

So perhaps I don't need to get with you, you seem just as disinterested in this as I am.

I've actually looked as re-casing multiple TBCs, some far more complex than the TBC-1000. All are possible, none are financially feasible (ie, case costs more than TBC). That leaves us to make unattractive clumsy mods that function. But function is the name of game anyway, right? It's not like the boring boxes (aka TBCs) were wall pin-ups.

He did, but that only works for his variant. Others must differ.

When you see all their hardware insides, and their apparent corporate culture (aka losing docs), you start to realize it was a company that got lucky with a one-hit-wonder lineup of products. Everything else they made before, and since, has been lackluster to craptastic. Even with the TBCs, some had issues, some were just decent, and two were best in class (best made to date). But it could have easily gone the other way.

A few reasons why this specific mod isn't for everyone.

1.) Those who are using consumer equipment will not have/need BNC. Those are more so for professional equipment that already have those connectors (even some professional equipment uses the standard 4-pin mini DIN connector).

2.) This unit uses the brown power board to output 5v, which is not in every revision of the TBC. So you can't just attach your PSU directly to the video board for those that don't have one.

3.) The back looks unpleasant. I know this doesn't affect function, but I personally like a clean look for my equipment. And now you have holes in the back of the unit for spiders and dust to get into. (Yes, this is mostly preference, I know.)

4.) This is not easily converted back for those who may want the amp later on (for whatever reason) or if it is ever owned by someone else who wants it. If you can get a bypass mod with the ability to easily convert back to original, I think that has its benefits.

Lordsmurf said it earlier, not all TBC-1000s are the same and there isn't a simple one-design-fits-all without some thought and testing put into it. At the very least you have to know how to solder, which not everyone who owns one of these does.

It doesn't just end there. There are s-video to BNC wires and adapters, but the modern ones all suck. Quality cables haven't been made in a decade or two. What we have now is thin garbage from China. Even the brand name Extron is lacking in quality, and overpriced. So whatever advantage you think you gain with BNC is pissed away due to cheap Y/C>BNC cables.

On the flip side, it now has heat vents. The TBC-1000 wasn't ideal in design, and the main chip gets really hot. Fans add noise, buzzy junk. All you need is some venting. Heat is always my top concern, aside frrom image transparency/clarity. Heat has driven lots of my mods to date, and not just for TBCs. I don't like in Canada, heat (and humidity) is a major concern.

To me, this isn't a valid reason whatsoever. The amp is usually crap, even when new and "working". Move on. Those who want an amp need to buy a quality amp. Not use the janky amp built in to the TBC. And that ignores the stupidity of including an amp in a TBC.

Or don't have the dexterity for it. I know how, but MS robbed me of the fine motions needed. It's not just "old people" that get stiffness in fingers and hands.

True. My unit usually sits by itself on a bench in an A/C'd room. For those who rack mount these, venting is not a bad idea.

Interesting, so even when they were brand new you think the amp should have been bypassed?

At the time, I didn't think much about it. But in hindsight, and for the past 10 or so years, especially these past 2-3 years, it became evident that including a TBC in a distribution amp was stupid. It's the sort of device that was made for a problem almost nobody had.

Most distribution scenarios were to reproduce low-budget videos, such as school graduations, band competitions, etc. But since the TBC-1000 was a premium over the TBC-100, the TBC-100 could have easily been housed separate, VP-299 left alone, and for the same price. Or a package deal from DataVideo. Just chain as needed. The VP-299 alone was fine, the TBC-100 alone was fine, but the Frankenstein "chicken wire and duct tape" quality of the TBC-1000 sometimes introduced noise and problems. And those problems amplified with age. The TBC-1000 started out decent, but the manufacturing became sloppy and haphazard by EOL.

And distribution was a niche to the overall demographic of the unit, most of whom never used the distro amp aspect. Just the TBC, mostly for the then-new (late 90s, early 2000s) desire to transfer videotapes to DVD.

Whoever decided this was a good product was lazy. Seriously, hot glue a TBC-100 board into a VP-299, and call it a new product? WTF? No QC whatsoever.

In this era of large HDTVs, high sharp compression, etc, I'm less forgiving to errors. What was once hidden by small CRTs, smoothing compression, etc, is now obvious even to partially blind grandmas. So viewing got better, these TBCs aged badly, and it's just not a quality item as-is. It needs refurb, sometimes board-level component replacement, and maybe a bypass. And yet, there are still issues at times.

You're a hard man to please, my lord. My VHS videos look great on my whopper TV, better than in VLC Player on the 'puter.

Not at all. And I don't think you're understand my statement.

The issue is devices that barf out noise. Those noises were hidden in the era of CRTs, smoothed-out DVD compression, etc. But this is literally 15-25 years later now, and (again) even half blind grandmas see the noises (and don't like it; "my vision already has enough problems, I don't need help making it look worse").

It's like somebody in the 80s realizing that 50s/60s items had problems that you were not aware of at the time. But now you are, now everybody is seeing it.

I value VHS, it is what it is.
But the TBC-1000 isn't what it should be, could have been, or should have been. It can be salvaged with modding and refurb, but stock TBC-1000 is now like Panasonic AG-1980, in that most units are having issues in the 2020s. Again, a device that is 15-25 years old now. It wasn't the best then (that honor goes to certain higher DataVideo TBCs), and certainly not now (due to aging factors).

Hence need for modding, refurb. Not just for "bad" units, but at this point, all units.

My videos also look great, at huge projection sizes. But that's a statement about my methods, my quality of work, not the TBCs being discussed here.
