Thanks for pointing to that thread. At least I know I have to get that partition recovered somehow.

Edit: Progress! I swapped the channel 2 attenuator with the aux attenuator and now the channels work. I took the opportunity to clean the contacts between the attenuators as well. Now all channels seem to work (at least in 1M Ohm mode). Getting the channel 2 attenuator out was a major PITA. There is a threaded standoff which got lose instead of the screw. In the end I managed to get it lose but I nearly got to the point to just try and break the screw. I'm not a fan of Lecroy's mechanical design 'skills'.

Edit2: In the process I have found a burned tantalum capacitor.

Following the kiss and tell spirit:

A Newtronics 200MSTPC AM-FM-Sweep/Pulse/ Function Generator for free. Guy sold to me and it didnt work on arrival. He was very nice and gave me the money back. I found a ton of cold solder joints and problems is fixed.

A Advantest Universal Counter TR5821 for $50. It was listed as needing 100Vac (Japanese model?). Here in Brazil is all 220Vac and 110/137Vac So I pulled the trigger anyway. When it arrived I opened it up and the main power transformer has all the taps necessary. Moved a couple of wires and now it is a 220Vac unit!

A Fluke 87-V, swapped a random old guitar pedal for it. Came broken, wouldnt turn off and displaying BATT. Fixed the damn thing with the help of you guys!

Yesterday was the last one. A Tektronix TDS-1001c-30edu. Nice 2 channels and 30mhz scope, looks brand new. Guy wanted $100 but was happy with $50.

Not completely sure this falls into the test gear category but:

and a Nissei HF/VHF power/SWR meter.

I have found worn RF relays to cause excessive noise in the past as well.

EDIT: On other LEcroys, I found slow updates to be cause by having a loth of math overlays/traces/calculations to be active.

Good progress. By all channels work you mean all but aux? If reseating and cleaning fixed all (all!) of them I'd undo the swap - the calibration files are matched to each FE I think.

BTW, check the big DDA-3000 thread, maybe with Converter's help you can hack it to 7300A
