Re: 7613 X-deflection issue
|
Hi , I would be thinking of returning the 7613 as that seems possible . I would be very happy to get a 7834 with plug-ins of any kind for as little as that - as long as the HV is ok and the CRT shows a waveform . I have one at the moment with an HV problem that I am trying to get working - the screen went blank and the scope wont power on now when I was using it a while back .fortunately so far the HV transformer and multiplier seem to be ok as the fault seems to be in the cathode supply side of things - I suspect some of the diodes in the voltage multipliers maybe failing .

Hi Brian, Thank you for your assistence! That is the point. If the CRT is damaged then the 7613 as a complete device will be lost. I try to contact the seller, a former Tektronix employee directly, who is living in CH. It is not so easy, because I got the device with help/support of a ?man in the middle¡°. But meanwhile I got the information that I can return the 7613! I am wondering, what he will do with the scope. Hobby moves on. In a couple of weeks I will get a 7834 including 7A24, 7A22, 7B92A and 7B71. Mainframe ok, half of the plug-ins defective. 50€ for all, so you can not complain. Regards Loetroelli |
