Hi Jim I'll bet the seller said that it was in working condition when pulled from service.... There are two identical crystals supposed to be in there - 100kHz. Tek part number is 158-0022-00. The

Hi, I've just received a 1L5 from eBay. On close inspection, there seem to be two components (crystals?) missing from the variable resolution amp board, component references Y344 and Y325. Can anyone

I have some bad news then. Without a Tek Scopecal ATE system or the software + all the required test equipment specified in the manual you have no chance. Even with this you will have an uphill
