LeCroy 93xx/LCxxx Power Supply Repair / Maintenance

[@roadrunnerForLife]

Good job! Thank You! Is there still the chance to get your shopping list?

[@MrTamhan]

Hello Harald, thank you for the kind words. There is a set of screenshots at the end of the video which show the parts at Mouser! Is this OK for you? Tam

[@roadrunnerForLife]

@@MrTamhan Well, I thought if I start with the replacement of the capacitors then I want to renew all of them, i.e. the two capacitors on the printer board, the four capacitors on the GPIB-RS232-Board and besides two big capacitors and five smaller ones within the power supply I think there are at least two further ones. Unfortunately I don't have access to my scope right now...

@@roadrunnerForLife Hi, the List AFAIK has all the parts I touched. But, when you are already inside, maybe also recap the graphics board...I did not do it on mine, and must now go in again...

[@roadrunnerForLife]

@@MrTamhan Thanks. Good idea. But besides that, have you ever thought of replacing the CRT with a LCD Display and its corresponding control?

[@MrTamhan]

@@roadrunnerForLife This is a bit difficult...I have researched it, but my FPGA skills. Do you want to try and tackle this?

Hi, Where's the parts shopping list you mentioned at the end of the video?

[@MrTamhan]

Hello, thank you for talking back! I put in screenshots of the various parts. But if you want, email me at [e-mail] and I will look the Mouser order up! Tam

125 degree caps? Why?

[@MrTamhan]

Hello, question of habit. Higher temperature means more robust...

Hello where is the pin 1 of floppy cable?

[@MrTamhan]

Hello, sorry, currently I do not have the LeCroy torn apart. But you can ask on the owners group if you want. Email me at tamhan aeht tamoggemon dot com for the details man

Hello I have a Lecroy 9340. It takes 30-60 min to start. What could that be? Greeting Lota

[@MrTamhan]

Hello, check the battery on the CPU board!

[@NicholasT-f9n]

I was gonna buy one of these for $200, but too big for the bench.

[@MrTamhan]

Thank you man. Fortunately, I have enough space here... ;)

[@snowbelldogold]

you look strange but also smart

[@MrTamhan]

Thanks for your feedback, mate!

[@snowbelldogold]

Are you really obsessed with technology or something?

[@MrTamhan]

One can say ;)
