The best, I think, would be for you to post some photos of your TBC & post them on this page so we can see them.

They are not mine and they are photos given to me by someone so will have to ask him for permission. But its pretty basic. See the orange board in the photos above, well that is totally missing and instead that 3 legged tansistor type thing is mounted where that spare space is on the TBC100 board. Power is input to the TBC100 board in that little clear/white connector next to the molex connector for PC use.

I plan to buy a TBC1000 this week. Will be interesting to see what version i get.

Here this explains it.

Also i have seen some with the RCA nd S-video connectors on the internal TBC100 board reomved and some with them still in place.

Could not add photo to above post for some reason

Would like to see the BNC connector mod mentioned by another member earlier in the thread too.

Here's my take on the TBC-1000 mod. I could've made it prettier but it's for work, not for show. :)

I got a new converter/TBC on the way so I went crazy on TBC-100 board. BNCs made a big difference compared to crappy DIN4/S-video connectors I used before. After modding is ready I probably will sell it if anyone is interested.

Final version. Had to insulate the BNCs because of Y/C - composite detection logic. Only 1 of 6 would've needed the insulation but meh. What's done is done. Also added separate ferrite cores for both Y/C in and out. TBC-100 board will pick up a lot of noise without the ferrites so I recommend every modder to keep the original or buy new ones. Cable used is RG174A.

Sorry, I did not understand which of the 4 is better:
- Cypress / TVOne 1T-TBC
- AVToolbox / TVOne AVT-8710
- Datavideo TBC-100
- Cypress CTB-100
I have forgotten anyone?
There are cheaper?

Howdy friends,

Looking for a bit more info...

What is the actual pinout for the TBC-1000 svideo & composite input/outputs ?

Going from svideo female to 4pin cd/audio plug
SVideo -----------------------------------> 4pin plug
pin 1 - Ground Y ------------------------> pin # ?
pin 2 - Ground C -----------------------> pin # ?
pin 3 - Y - Intensity (Luminance) ----> pin # ?
pin 4 - C - Color (Chrominance) -----> pin # ?

And RCA female to 2pin IDC plug
RCA -------------------> 2pin plug
Signal ----------------> pin # ?
Ground ---------------> pin # ?

Just wanted to confirm before I order the cables, thanks kindly,

Higher res shots:

Also got a Panasonic NV-HS 1000 and I am quite happy with the quality.
Was not very happy with my JVC HR S8960E I bought new years ago. (DNR leaves artifacts sometimes).
Only thing that's still left on my to do list is exchange the ADVC 110 to a Backmagic Intensity Shuttle well and probably do the TBC-1000 mod as well.

Mine seems to have the connectors already on the TBC-100 and even says DataVideo TBC-100 on the board...

Do you still have any of these modded cables for sale?

Stumbled on a tvONE 1T-TBC from Adorama on "closeout" for a shade over $500 delivered. Despite the warns from LS about the different version logic boards wearing the 1T-TBC badge, figured I would take a shot at this and return within the 30 day window if it doesn't fit my needs.

Below is the logic board - quite a bit different layout from the board on the first page of this thread.

It passes video as expected when a tape is playing in my JVC HR-S9900, but when the VCR's default blue screen is displayed, the 1T-TBC shows a vertical scroll when watching in VirtualDub through an ATI AIW 7500.

That is a bad unit. It has frame sticking/ghosting/etc, flawed chips. It will do this during tape playback, not only during a VCR blue screen. There are good 1T units that are essentially AVT-8710 clones, but those are not easy to locate, as those are about 15 years old. The bad unit at only 5-10 old, and more in circulation, with the main reason being these are flawed junk.

At this moment, I do have some good 1T's in the marketplace. But that won't last long.

Thanks - I did a bit more digging around the forums and found this thread:

Which goes into further detail on the issues with more recent revisions of the 1T-TBC.

Printing the return label now!
