Tektronix 434

Hi, guys, does anyone have a Tektronix 434 service manual? Operating manual? Have been searching on google to no avail... Thanx.
 

Re: Tektronix 434

Hi, karesz,
Thank you for the link. Is there a way to get hold of sections 8 and 9 (circuit diagrams)?
I was recently given this scope but it has some problems with the horizontal deflection (timebase) circuits. I was told that these Tek scopes have been plagued with trimming capacitor flaking...
BTW, is there a way to decode the serial number to get the production year?
Thanx again.

I found yet at "bama" Tek 432 Manual(56MB), but what is difference?
https://bama.edebris.com/manuals/tek/432/
Some time I buyed pdf-Manuals on CD from www.micromanuals.com (Huston), their are regularly not so expensive (1-20$) and with relative good scanquality...
I see to by at www.valuetronics.com, usually(as I know) their sells manuals too.

Re: Tektronix 434

Thanx, karesz, for your help. Yes, I had already downloaded the bama manual. I guess the only difference between the two scopes is that the 432 is not a storage scope while the 434 is. Electronic circuits inside should be quite similar (at least, I hope). I would think that the first thing to do is to clean all the contacts, though they seem to be gold-plated.

Hi fun!

I think too: first step must be every times a good cleaning, check the electrolythics_SMD Alu elkos are often very beed on leakaging, you can see "lot acid on work" at PCB-cooper...
Of course all contacts of switches, and so on.

In my 5 years old PC was a 105C ALu Elko a week ago "OUt", opened hes top, but the PC isnot warm in their region too...


I founded the "Tek User groups" address for you, but I dont know if it is working yet...:YahooTEK-Forum!
