Yes good luck with the caps/corrosion on your TDS !  :scared:

But if it' free, worth a shot !  >:D

If not repairable or too much work, you can always sell the parts on Ebay, should sell like hot cakes.

Can't wait for the pictures and progress reports, get cracking !  :box:

I don't know if USA ham licenses have to be renewed or not.

As I recall my 11 meter license was permanent. I still remember my call sign even though no one ever used them. KBHY5427.   :D

After chasing my tail on the Error 05 on this R6144 Volt/Current Generator, I opened up the User manual on a whim and saw that there was more info regarding the error messages than in the Service manual!

The service manual says "Check these parts: blah blah blah" and nothing else, not even what the error means. The User manual says "This error means 'this', press these buttons to fix it".

Turns out Error 05 just needs the SRAM reset, so once I pressed the magic button on boot, it was all cleared, no errors any more. Fkn hell, if only I had read the User manual to service this unit instead of being such a dumbarse to go straight to the Service manual.....  |O  :-DD

Anyway, now it boots with no errors (but... I did find and replace a bunch of faulty parts, so not is all wasted anyway, and I know all logic chips on the processor board are good now....). Next step is to wait for the replacement flat-flex cable to arrive from Aliexpress to replace the existing busted one for connecting to the front panel PCB.

All going well, I'll have a functioning R6144 soon, ready for adjustment and calibration. Then I'll use it to calibrate my TDS210 scope. :)


Anyway, back to the important things, polishing off my 5th Smirnoff.  ;D

Good to hear the fix; meantime I've checked my stock of LT1021-7 ;)
Unfortunately, I don't have LT1008, only his evil twin, LT1012(slightly better performance, different compensation, identical internal schematic)
Enjoy the R6144.
