From Tim P (UK) Yes, I discovered this trick when I removed the four screws in the base of aTM502A, and the entire PSU slid out and landed in my lap ! Someone on this group published a photo of a setu

from Tim P (UK) I have a CT71, although, for me, it is used mainly for checking Tunnel Diodes. It's certainly adequate as a go / no-go tester, and will show the switching current. Tim Tim

from Tim P (UK) How reliable are the J-FETs (usually 151-1004-00) used in Tek plug-ins? Also, does it really matter which way round they are in the sockets? The manual shows Source, Gate & Drain, but

Is it possible that the parts 'C' will go over the barrel of something like a P6008, without its 'hat', and touch the ground contact that can be seen through one of the slots in the barrel? Tim

from Tim P (UK) Yes, I expect the lucky owner may well be asking about the 1S1 and it's foibles ! I have four - one works, but needs the Loop Gain tweaking every time I use it, one triggers but won't

Yes, the DB-25 cut-out on the 54xx display is for Option 03, user-programmable readout fields. Tim

Ah, yes - I hadn't appreciated the opportunities for mischief with 'tinyurl' Probably why it is not used now. Tim P terrell.michael.a@...> wrote:

What about 'tinyurl' ? or is that just another level of complexity ? Tim P terrell.michael.a@...> wrote:

From Tim P (UK) From what I can see through the layer of crud, the red badge near the calibrator knob is the logo of Livingston Laboratories. LL were a high-end Lab instrument hire company in the UK.

From Tim P (UK) Just got back into my quest for a working 5441 - I've given up on the instrument with the 'howling CRT' and bad storage board; that one had the fault where it would fade positive in NO

AH, yes - I've just downloaded the service manual. Makes a lot more sense now !! Apart from the Philips and the Tek 7704A, all my stuff is linear. Never got round to looking at the schematics of switc

From Tim P (UK) I ask here as I saw this mentioned regarding a Tek 22xx-series(?) My problem is a Philips PM3311 which popped a RIFA capacitor, with copious amounts of smoke. The PM3311 has this cap a

yes, of course - I'd forgotten the AA501 and AA5001 distortion analysers. Tim

From Tim P (UK) ebay: 193462625382 Even has a Tek cal sticker on it. I suspect the only thing 'Tek' about it is the case. No internal shots either. Anyway Tektronix never got into audio gear ?? curiou

From Tim P (UK) Many thanks for that - as I suspected, it is necessary to unsolder the delay line and re-attach to the interface board. :-( Otherwise a topological conundrum involving a fourth (spacia

from Tim P (UK) Does anyone (Hakan?) have the documents detailing the conversion between rack / bench formats ? they are 040-0583-02 and 040-0584-03 I don't see how to do it without unsoldering the de

From Tim P (UK) I don't know if you have seen the P7001 section on TekWiki - it's under 7000 series, as it uses the 7704A. Lots of pictures of the 'guts' of the P7001 and some stuff on the interfacing

Hi Egge; no, maybe I didn't explain myself very well - the 'sockets' I referred to are actually three individual tiny contacts on the PCB into which the transistor leads go directly. Not an actual soc

from Tim P (UK) What was the thinking behind the 'soft' transistor sockets used by Tektronix in some of the 5000-series 'scopes? I am working on a 5113 / D13 that has these on the storage board. Seems
