Out of Production Hardware / Re: Tracker 2000

But this was not made clear in the Ebay sale.
Your comment "try this (the same tube was used in the 1000 and 5100DS):" does as you say state good for the Tracker 2000.
The self-employed engineer cannot afford stock of useless expensive components that might do the job!

But you make no comment on this:-" Perhaps Curtis will give this his seal of approval or not!"

As I mentioned in an earlier post, the same tube was used in the Tracker 5100DS. These products were being manufactured at the same time and we only used one tube type at that time (the Toshiba).

Many thanks James
I have already replaced all the electrolytics including the 2 x 3300uf and the 1 x 1uf as from past experience they do go leaky and it was my first thought. I'll source the diode's from element 14 here along with the ceramic many thanks again.
i'll post the results once fitted and here's hoping

Hello Steve
If you suspect the doubler diode circuit DI & D2.
These are down in the Huntron Maintenance Manual as 3 KV, with the Part No. HV30.
This diode appears to be obsolete, but you could use this from Farnell:-
https://uk.farnell.com/search?st=3%20KV%20DIODES .
Or these from RS:-
https://uk.rs-online.com/web/c/semiconductors/discrete-semiconductors/rectifier-diodes-schottky-diodes/?searchTerm=3%20KV%20DIODES&applied-dimensions=4294277268 .
Or these from Digi-Key:-
https://www.digikey.co.uk/products/en/discrete-semiconductor-products/diodes-rectifiers-single/280?k=3+KV+DIODES&k=&pkeyword=3+KV+DIODES&sv=0&pv2071=u3000V&sf=1&FV=ffe00118&quantity=&ColumnSort=0&page=1&pageSize=25 .
Perhaps Curtis will give this his seal of approval or not!

While I was at it I'd replace  electrolytics capacitors  C16 to c19 1 Uf 450 V, and C20 ceramic  0.01 Uf 2KV.
All theses available from the above companies.
Have I saved you the cost of a new C.R.T?

Hi Curtis as I said earlier the Caps at C18 and C19 run very hot to the touch with the tube both in and out, I've removed the diodes D1 and D2 and found a very slight difference using a meter both measure O/C one way and one measures 1.1818 the other 1.1845 climbing to .1859 the diodes are HV30 do you know where they can be purchased in say a 5 quantity and not the 1000's or do you think they are good?
thanks for the ebay link but I think those tubes are not for the 2000

I still don't see why the early versions of workstation up to Ver. 4 to 4.2 should be charged at the same price as the current version 4.3 +at Price: $3,495.00 !!
I guess last years Workstatation is just as valuable, unlike last years car, iPhone, or Windows operating system!!

Not good to have photographs that pixelate when you want to enlarge the detail!

Different part number Curtis.
The Ebay link you give doesn't claim to be good for the Huntron Tracker 2000.
The Huntron C.R.T. had the Huntron Part No.07-4018, and Toshiba Part No.85 DB31.
Just says:- Huntron 407-4018 3" CRT
For use with Huntron 1000 / 1005 / 5100DS
Tracker Component and Board Analyzers.

That would be for the next generation of Huntronians to decide.
