Would anyone know how much a Tektronix 2712 spectrum analyzer and the 2707 tracking generator would have cost brand new? Thank you in advance. Mike K8MB.

Stupidly, I didn't look well enough before removing the power switch bracket on a 465 I'm working on, and this part fell out... I can't figure out where it goes or what the intended purpose of it is!

Hi Dennis, I'm afraid Craig is right, the prices over this side are crazy. Partly I suspect because there are far fewer around but mostly because prices on everything are way higher. Having read

Dennis, there's no need to be stunned by the complexity of the 577 amplifier. It is quite complicated, but the reason is simple. The 577 senses true DUT collector current on the high-side, right from

I love reading those old bulletins. Thank you for that. I hope the deoxit cleaning along with the reseating means that that issue is solved. At least for a while.

cmjones01 That's the symptom of one of the trimmer capacitors going open-circuit on that channel. I think it's the one labelled 'LF' or 'MF' but I can't remember exactly. It's easy to identify

Thanks everyone for your great input on the subject, was much interesting ! This forum just never disappoints, there is just so much knowledge and experience in here, I just love it :-) As destiny

checked for there Wow - 1000! In the whole of Europe there are 15 listed as shippable to the UK. And they sell for anything (looking at completed listings) between (converting to USD) anything between

The p-p voltage is around 0.4 mV, not 2.5 mV. I forgot to correct for the cascade amplification in the 475. This amplitude makes much more sense to me. I can see the 1 KHz signal on the 453 as well,

Hi Fabio and Lop Pol, I mentioned checking the Z-axis adjustment because it's easy and non-critical. Unless there is a component failure, it hardly ever gives trouble. From my experience, two

I was stunned at the complexity of the amplifier in the 577. It is extremely sophisticated, fully differential, modulated and demodulated and I recall trying to troubleshoot it in vain. I was

No need for the circuit discussion. This is pretty basic. The important thing was the concept. If I can find some time to try it (that's the big problem) I will report back. I also like my idea of the

Hi Craig, That is very disappointing. I don't understand why that would be the case. The whole point of finding a tube tester was because they are so obsolete by now people are just throwing them

1) Availability, 2) How deep are your pockets, 3) What do you intend to use it for

What's a good source of 12 feet of RG174? A customer wants to make an extender cable and I'm out of supplies of Coleman RG174 in 1000ft reels.

You need a pair of P6451. And don't get the ones where the cable comes off the side - it is for the Sony/Tek 308 and it won't fit.

Hi Lop Pol (again), As others answered, it seems those tiny 5mm trimmer caps are prone to fail. I had one of such failed on the pre-amplifier of my 464, and had also one failed on the vertical output

I have been thinking about this for awhile. I have played with it a bit and it seems to function somewhat ok. Opinions? Nielsentelecom
