WTB: Tektronix 7D01 w/DF1(or DF2)

 

Hello Ashton,

My limited experience with bad electrolytics in Tek scopes was that there is
no capacitance. I would guess, the problem was discontinuity rather then
drying out, because failure has been sudden, every time.

In view of that, I wander how much help would be an ESR meter. However, I am
looking into building one myself and would be interested to see what method
you are using. Let me know, please, and if you have the schematic in a
convenient form to e mail, please do so. A rough sketch showing only the
principle is good enough, too.

Regards
Miroslav Pokorni

Apropos - I sold one of [the pair] to a person in Spain via eBay, many
moons ago. Also sent a HP --> UK with no problems. 7D01 arrived OK via
US parcel post. I could occasionally be a middleman: some wimps on eBay
check the "US only" box. Thus if you just gotta have something from such
a seller - perhaps I could tranship for you. My local post office is a
few blocks away and tiny = no lines. You'd have to be aware of size/wt.
limitations and apprise me of what to put on for customs, given your
local conditions. (I have PayPal - not sure if that is Int'l yet, but
it could work for paying seller while waiting for your funds..)

Doubt this would be practical for say, a 519! or anything so massive as
to virtually demand 'foam-in-place' to arrive safely, but I could repack
smaller things - according to physics Laws.

(This doesn't mean to be an ad - but, I have quite a few Teks too; from
2xx, 3xx 4xx - and 7xxx from pristine to.. 'needs ~ work'. Even Rb and
a quartz freq std and a spare 7854!. No, not a resale bizness - though
it sometimes comes close.. in swapping for the keepers. As I'll likely
Not get to doing minor fixes on several I planned to, anytime soon :
well, nuff said)

I encountered my first Tek (514AD?) at LBL in '56. Amazing to be able
now to acquire the best of the best, as I see the toy digital displays
drawing pretty pictures.. sometimes divorced from er reality or, if you
want near-Real: at $20K+ $US. {sheeesh}

Built my ESR meter from 'Stralia via Canada.. but haven't yet let it
attack those stealth-bad electrolytics.. in a couple 485s {sigh} It is
a nice hack though and.. it actually does read ESR! (equivalent series
resistance - too many TLAs in the world)


Just a thought,

These come up fairly often on eBay. Seem to go in the range $10 to $60
for
the whole lot. There are three sets for sale right now on US Ebay.

Hi Craig and the group,

Yes, I know... but I prefer a seller who can check it and says something
different to 'as-is' or 'not checked' or 'I don't know how it works but
guaranteed not DOA' ;-)

Regards,

JOSE

Good morning!

Thanks!
