Random question. Decided I’m doing a full restoration on this fluke 8050A when it arrives. Factory condition or bust. Probably the latter but we’ll see.
That means I need to source some NiCd batteries. Does anyone know anyone in the UK that still stocks them?
Www.batteriesplus.co.UK. Painless transactions for some tagged sub-C NiCds.
I've used them before, a longish time ago. Long enough ago that I can't remember if there was anything particularly good about using them, but not so long that I'd have forgotten if there was anything bad about them. So, that's a rather half-hearted recommendation for them; and it should be made clear that the half-heartedness is entirely down to caution about my half-memory not about the vendor.
Apparently I can’t add any nickel cadmium batteries to the basket on there.
So far TME is looking best bet. Will formulate an order as I need some other bits.
Well
HELL...! I guess
Canadian Tire really
DOES have it all...
Unlike my local grocery, where they just gave me a look like a tree full of owls when I asked where to look.
mnem
FORE!!!

That's a
tiny bit irritating. I
was going to flog some of the 64 tagged subC cells I bought for £14 (nominally expired 9 months ago). Now I'll keep them for my fetish, Tek 1502s.

Yeah I would keep hold of them. This 8050a is going to cost a few quid to restore by the looks. If it checks out it will be worth it though. It does relative dB measurements at specific impedances which is going to be very good for my audio projects coming up.
Quick update to my NGB 32 / 10.
Today I've replaced all the tantalums and electrolytic capacitors.
The main reason for the failure was this exploded tantalum C12 (shortened).
This caused a lot of havoc.
Dead parts so far:
- BD 139
- BD 140
- 3x BC 107B
- 5x LM 741
- 2x 1N823
The 1N823 I didn't have them in my stock, ordered some MIL-Spec ones
from the bay.
Oh, and the original tantalums were rated with 16V. I've replaced them with 35V types, because they have to bear 15V.
No idea what R&S had in mind when designing this PSU.
Will keep you updated.
Good night.
How hard is to repair the HP 34401A with this kind of error ( error 604 ) and "Bad display, Self test fail. 604 error, A/D convergence error. Front/ rear input switch missing.
Missing rear bezel and handle.
eBay auction: #293578836763 ?
Because these 3 meters from the same seller goes for 148 USD, very tempting offer after reading the xdevs :

Spot the problem.

I started off wondering what the heck is wrong with this picture.....?
Then I saw it.
(The bruise should fade in a few days)

Is it really wrong though to heat sink a connector just to be on the safe side?
(joking of course)
Good point. I agree that they should have banned the things but only for consumer shit that ends up in landfill.
The crappo charger in the 8050A is guaranteed to cook your NiCds in a few months.
Then you have created more cadmium waste that has to be dealt with.
... it seems you're looking for TEA endorsement.
Hate you when you're so damn right.

The seller is fine, I have purchased a Fluke 8842A and a HP3468A from them, but that HP34401A, I wouldn't touch that with a barge pole. Those switches are not standard ones, well the switch might be but not the push rods that operate them, they special cranked to make contact with the switch, which if you check them out are not on the same plain or in line with the button on the front panel.

Good to know, I assumed the repair would be possible since xdevs.com could do the same according the same error for this ebay link in particular but I believe you.
Pics when it arrives .....
