My bad experience of groups that enable editing is that 30% or more of posts get 3-5 edits each which more than doubles the message flow. So my vote is no. D.

Very fast ticking suggests to me that the over-voltage protection in the switching circuit may be being triggered. Check the 120V Zener VR3059 and surrounding components - that 1uF cap (C3050) can be

Not 100% sure about the 7704A but there's a third level as well which is "balance" where all the different voltages are fed via a set of balance resistors to a summing junction on the IC. If that isn'

There's nothing there. Why not post your pictures into t new folder in the Photos section of the group. David

Yes, running without a load is pretty much g'teed to make these PSUs tick. Dennis Tillman published a design for a 7K dummy load for 7854/7104 and I'm pretty certain it is good for the other 7K models

Hmmm I've not heard of HSMS232x - did you mean HSMS282x? I have quite a few HSMS282R (uncommited ring quad) which I used in my SG504 levelling head replacement, and it might be possible to press those

Hi Francesco, Welcome to the group. I'm sure someone will be able to assist you David

5% or 10% typically, so 83V for the 82V Zener is OK, and also 6.6 for the 6.2V Zener is probably OK (depends on the part if 5%, then it is out of spec assuming used at datasheet current. 6.8V across t

Thank you, I've uploaded them to the Datron-Wavetek group files area, so please delete the rar file from the Tekscopes file area. David

Shapeways shipping to UK has got stupid expensive lately. I need to find a UK based 3D printer that will SLA print in nylon. PS If I do find someone, will you make the models available for DL? Thanks

Any more Climate Change denial or defense posting will result in the offenders being placed on moderation. Please keep politics etc. out of this group. David Partridge (Group Moderator)

Oh yes and I forgot - it needs to run Windows XP Embedded as some of the driver software doesn't like W7 or later. David

Yes, I got that thanks, problem is there's no room inside the case to add a card like that. David

AFAIK both the M765 and M780 are socket 478 which is what this board has.

Problem this scope *needs* the PCI/104 ...

But I can get Crucial brand 1GB on eBay for about £5 ... I didn't know the price had dropped so far!

Thank you Jared, I've sent a pm to arrange shipping details etc.. David

Not a dumb question, but changing the mobo in a Waverunner Xi is apparently somewhat of a challenge. It also needs to work with XP embedded. David

I have a scope (not Tektronix or HP/K/A) that uses the BCM MX855 mobo with a 1.3 Celeron. I'd like to give a late life performance boost and an told a Pentium M765 will do the job and maybe even an M7
