B+K 2133 Frequency Analyser

[knobtwiddler]

Hi,

I don't suppose anyone here might have a service manual for a B+K 2133? Google searches don't reveal anything. My understanding is that B+K will service it, but the minimum service cost is several times what the machine is worth in a working state, so it's a case of fixing it in-house, or having an interesting doorstop.

If no manual is forthcoming, does anyone here have any experience with B+K green-screen analysers? (aside from keeping away from the HT when the back's off it...)

Thanks in advance!

Telford Electronics are often a good source of B&K manuals - you could try asking them if they have one. Note that the service manuals are separate from the user manuals, and can be quite large and expensive for the more complex analysers.

Thank you, Dave. I have sent them an email.

NB - from what I can make out, the 2133 is basically the the same thing as the later 2143. Howver, whereas the 2143 has an LCD display, the 2133 has a green screen CRT and is about 10 x the size and weight. But as we all know, you can never have enough green screens in the workshop. I am concerned my particular example may end up propping open a door.

Correction: it does not have a green screen (is B+W).

You could put a green filter gel over the front...

I wrote to B&K when I needed a manual, they were very helpful and sent what they had.

It didn't occur to me, as most OEMs of high-end test gear (won't mention names...) tend to keep diagrams and service info strictly to themselves. Thinking about it, that would be a little daft for B+K as no one in their right mind would send something this ancient to B+K to be fixed at £100+ p/hr rates (an acoustician friend tells me B+K rates are very high - probably well over £100 p/hr). If they enforce a policy of not supporting 3rd party engineers on old kit, it would render much stuff over a certain age to the skip.

Thanks. Email sent.

Most companies I've written to have responded and sent schematic's etc. One valuable lesson I learned early on in life is "if you don't ask, you don't get". If you supply model/serial #, be brief, ask politely, and say you won't sell/share said info if instructed, Bob is usually your proverbial Uncle.

Good luck, Andy.

Update: have politely asked just about every test gear specialist (inc. B+K UK) if they have a service manual to no avail. Am beginning to think I have a boat anchor on my hands. Beyond doing the obvious such as spraying Deoxit into connectors and checking seating, I doubt I can do much.

When you turn it on, the vertical hold rolls. There might be a message, but I can't move my head fast enough to read it.

That's a shame, guess all you can do is keep checking ebay for one and maybe ask on the EEVblog forum. When I wrote to B&K for some bumf on a couple of bits of test gear, they didn't have much.

I, unfortunately, have a 2033R and 2131 analysers.

I contacted B&K and was told they keep no information on older equipment, not even a library copy, they are that proud of what they made.

So, they are scrap. I was just looking over the weekend at my two analysers and the rubbish method of making them and accessibility meant they were of no interest. Shame, they are 70's era spectrum analysers and I am sure they would be of interest to museums etc.

Never buy B&K equipment, waste of money.

Artek have one of the manuals of mine.
