Hi,

Thanks for the information, will keep looking. its a nightmare for parts at the moment, am only short of about 6 parts now but its taken months to try and sort parts.

Thanks again(am in the UK)

Hi Steve, I'm not immediately seeing any replacements that don't have several month lead times. Parts availability is getting to be a problem.

That part is just four resistors side-by-side in a single package. You could just solder on four individual resistors side by side and it will work fine, but you will have to go to a smaller size for them to fit without touching each other, probably 0603 would work.

I don't know what country you're located in, but here is a 150 ohm resistor in size 0603 from the US: RC0603FR-07150RL. Of course instead of 1 you'll need to buy 4.

Hi,

Is there a alternative par for 743C08315JP  Res ARRAY 150 OHM 4 RES 2008 please.

Thanks

Great, I'm glad that fixed it.

...can I use a linear servo for elevation and still use the pan effect in the same way as a regular servo?
Yes, it will work the same!

Luke,

Many thanks for the swift reply.

I set the baud rate to a different value 9600 then back to the recommended 38400 and now it seems happy.

To save a new thread can I use a linear servo for elevation and still use the pan effect in the same way as a regular servo?

Ok, sooner than expected, the fix is here. Big thanks to Mr Heclo. :)

Small but important update here. I lacked SD card reader so I could not test it until the one I ordered arrived. Took ages to arrive from the far East, sigh...

Well, the thing is, the version with 24 user sounds that Heclo did is not working correctly, but he is working in a new one. I (or he) will upload it here as soon as we have a version working.

Did you set the baud rate on the 2x60 using the utility on the "Misc" tab of OP Config? If so, you may want to try doing it again a lower baud rate, I believe the Wiki recommends 38400, but you can go all the way down to 9600. You change the baud rate for the Sabertooth by changing the value for "Serial 2" on the Misc tab, then use the "Sabertooth Baud Rate Tool" to write the setting to the Sabertooth.

Open Panzer Help / Sabertooth 60a ESC problem with TCB
« Last post by minimivic on January 16, 2022, 07:31:26 AM »

Fitting a TCB into our 1/6 king tiger which has an existing Sabertooth 60A ESC 2x60 v1.00.
We get no control via serial (well some eratic control). Sabertooth set as per TCB manual and connected correctly.
TCB set to sabertooth in config.

I have another T34 1/6 with very similar setup using a sabertooth 2x32 and TCB which works fine. I have swapped the TCB's over to eliminat that. The new TCB works fine in the T34 on the 2x32 with the same setting.

Any ideas?

Hi Luke
thanks for the vote of confidence!! It took me a while to work up the courage to attempt the reflow process. In the end that wasn't the hard part!

The critical points are getting the right amount of solder paste on the pcb using the stencil ( very important that it is clean first) but you can still get a bad result if you are a bit shaky getting the stencil off as you can smudge the tracks and get bridged joints.
 Your points about the amount of solder paste etc and scrapping the heat sink pad under the amp chip is very important for good results. As I said I think with a bit more practice I could get a better result.

I did have some bridge pins that I was able to fix with a fine tip soldering iron and a solder sucker. However it pays to check the circuit layout first because trying to fix bridged pins can sometimes make things worse. For example there are some adjacent pins on the amp chip that wouldn't matter if you did have a bridged joint as they are connected together via the rest of the cct so it would be best to leave them and not tempt fate.
For instance pins 1 & 2 connected together and then to speaker terminal and 17 & 18 to the other terminal. Pins 23 & 24 go to GND and pins 21 & 22 the same to GND.

So the boards that don't work I don't know if the amp chips are ok as the chip does have some protection in built against shorts etc. But at less than $4 a chip it is not worth the hassel reusing them to find out that they are stuffed.
