In the shop collection are about 20 complete ENi PCB's, no cases or meters. These were dogs that weren't economically repairable,20 years ago but now they all work fine, half with new Russian

In my modest collection there are 3 yellow CDV700 6Bs all ENi's, original not modified. The oldest one is serial #15 and has the smooth top casting, the newest one is over 19,000 and has the raised

Good info Michael!. With the PCB layout, we COULD have that again if they don't.Geo

Hi Michael, Thanks very much for the offer. However, I really would like to start with a known working unit. I really don’t want to troubleshoot another of these. Particularly since I have exactly

digging through parts box, found a new build ENI switch assembly I had bought sometime last year from anythingradioactive out of England.? I don't think they have these anymore, i don't know.

Lithium chemistry doesn't tolerate over charging. For example a single cell on a constant current/constant voltage charger could charge a cell at a max current rate of 1C, in the constant current

Good info. I need more knowledge about paralleling cells, Series/ parallel, how the internal charge controls work, do they all have internal PCB for charge control, if not what needs to be added etc.

Geo: Lithium Ion?????????????????? Lithium Iron Phosphate fully charged????? 4.2V????????????????????????????? 3.6V discharged?????????

Update, Li cell 18650 on DigiKey, data sheet shows the one they sell as 2600mAh or 2.6A/h Other sources claim far more but one wonders it that's advertising hype. With even 100mA current, which should

Many Geiger Mueller probes are available that will work on the CDV-700 but they don't use the standard 900VDC that all 700's provide. We've developed several circuits to address this issue, both in

As mentioned in another Bucket List post, " Not surprisingly, battery Voltage when using dry cells is not stable over time. I jokingly call dry cells a 1/4 cycle AC generator. Compared to a real sine

This test has been on the Bucket List for quite a while. Bottom line, yes they do work, caveat: they don't work quite as well as an actual 2N404A but are easier to find, at least they were when I

I have what I believe is an Anton board - the transformer sticking off the end.? I might have two of them. Not in cases, just the boards.? Not sure if they work.? Yours if you want them.

Cool project Lenox! Wish I had one to send you.Geo

After looking at the schematics of the various models of CD V-700, I have become interested in the possibility of converting the Anton CD V-700 to operate on two D-cell batteries. So, I am looking for

Yes of course Chris, 2001 I get a little shaky when writing about that day. The evening before I was having a chat with some mutual friends via internet voice chat, one w orked in the Submarine office

"In 1991 when the first plane hit".... I think you meant to say 2001.? I remember that morning very well.? I worked at IBM and was well paid.? Life was good.? That morning I turned on the news

Michael, on the transformer theory, real basic stuff you know already- Voltage in-out is straightforward, it is directly proportional to the number of turns in the "primary" or" power applied winding

no, never got the 4-2 to work. interesting ________________________________ Sent: Tuesday, May 24, 2022 9:24 AM To: CDV700CLUB <[email protected]> Subject: Re: [CDV700CLUB] CDV-700 Transformer

Update on the missing transformer. No wonder I couldn't find it Michael, you had cleverly hidden it in a clear plastic bag marked "eBay Transformer". But find it I did, bad new I couldn't get it to
