Re: Test Equipment Anonymous (TEA) : Discussion and Group Therapy Thread
Cossor had a distinguished history, being important in the development of CROs and radar. They made a fair amount of test equipment of various sorts. They came unstuck around 1960 over disputes concerning the Fylingdales early warning system and were bought by Raytheon, who were presumably interest...

Re: Test Equipment Anonymous (TEA) : Discussion and Group Therapy Thread
They made some fairly ok ones later on into the early 1980s. Up to 100MHz dual trace delayed sweep.
Also I used to work for Cossor back in the day. Mostly full of people who hadn't got over themselves yet![Laughing :lol:](./images/smilies/icon_lol.gif)

Re: Telequipment D32
Quite possibly. I was presuming, possibly optimistically, that the equipment had started with decent cells. Even those could be compromised by a shite controller. Oh no it'll be shite cells and a shite controller. Is it possible to get anything else? I mean even the old SLA chargers were shite and ...

Re: Telequipment D32
The possibility of shite controllers are one reason I don't like leaving low-end equipment containing Li batteries charge unattended. A wise move generally. I am less worried about the controllers than the cells themselves. The cells can look perfectly normal to a charge controller even if they are...

Re: Telequipment D32
Further thoughts to ponder on: Scope ON = solid color LED and/or flashing if being charged. Scope OFF but charging = LED in a flashing state, changing to a different but solid color when fully charged. It's getting whatever the shite charge controller does out of the box :lol: The possibility of sh...

Re: Telequipment D32
............. The intent with this is to "modernise" it. The original design is a 7.5V 4Ah (30Wh) supply which gives 3-4 hours of operation. We can do better than that now. So what I am probably going to do is the unthinkable and eviscerate the entire mains front end from it right up to t...

Re: Telequipment D32
I must say it's not a thing that would have tempted me, but each to his own. I had a quick look at the manual and it said the batteries were necessary as they were used as giant capacitors. Finding replacement NiCds may not be easy these days. They were very tolerant of charging regimes and in part...

Re: Telequipment D32
Yeah yeah yeah on it. Ok so the D32 arrived nicely packaged. It's a very compact little battery powered scope. 10MHz dual trace. Nothing fancy but incredibly useful as they are light, don't take up a lot of room and of course can be easily floated (consider SMPS). Also 100% fully discrete with no fa...

Presumably you are going to have a Naftalan oil bath for wellness (pun intended) reasons. Do the travel insurance companies say it is OK except for Nagorno-Karabakh and the Armenian border?

Telequipment D32
Ok so I was scrolling through eBay on the toilet this morning, like you do when you haven't eaten enough fibre for a couple of days, and guess what? I received a stupid low offer for a Telequipment D32. It's a very basic 10MHz dual trace scope which is by modern standards, not exactly that useful bu...

Re: Interesting findings on the internet
I always regard rebranding as a negative. Either there is something to forget, or the managers know something isn't right but don't know what to do. That leads to "something must be done, this is something, this must be done". Always unwise to concentrate on either the wins or the losses....
