till, Did you mean 7A13 (100MHz diff amp) rather than 7D13 ?
try Stewarts of Reading they have 7A22 & 7A13 (but not 7D13 - ADC ?)

Metcal Soldering iron
Metcal irons are worth the money. . .if you get them from eBay. They are great to use and with the instant change tips can handle almost anything. But new they are far too expensive.
A used one can be had with stand for around $100. The tips are expensive new ($30 or so) but they last a very long time. And are often available on eBay.

Irons and Meters
I have checked out Metcal irons on ebay and they look very nice...but very nice and expensive.
Whats so special about them.....that power supply looks quite fancy, is it an invertor or something??
As for the previous comments about Fluke Scopemeters, again, lovely, but ooh, the price!!!

my bench has too much stuff
but the things which I use most often are:
Wavetek 180 Sweep Generator
Heath IG18 Audio Generator
Tek 3032B scope
HP Meters-- 3478A and 3468A
Heath IP27 Power Supply
Lambda +/- 15 Volt op amp supply
Fluke 3330B Voltage/Current Calibrator
Genrad 1658 RCL Bridge
HP339 Distortion Analyzer
Tek TM504 with a couple DVM's
Fluke 177 DVM
the only instrument bought new is the Fluke 177.
i use a HAKO soldering station, and a weller 7 watt soldering pencil -- buying a soldering station was a very good move.

The special technology of the Metcal is a variation on the Weller temperature control using the Curie point of the metal to control the temperature of the tip. However unlike the Weller, that has a switch and a magnet, the Metcal uses a high frequency generator to directly heat the tip. Doing this means that the tips are reallly small and heat up instantly. The power supply is much more complex than the more conventional irons and can put as much as 50W into a tiny tip.
On eBay they are usually around $100-$150 for a PS2E supply plus handpiece and stand complete. Don't get the earliest version with one LED on the front, the later ones have 2 LEDs. The newer models work the same but cost more.

Genrad 1710A Distortion Analyser (like the one John Curl uses) anyone?

Konnichiwa,
I used to have pretty decent stuff, it all went one way or the other, fairly recently my 50MHz 2 Channel Philips Valve 'scope died and other stuff went. So I had a good hard look what I felt I really needed to diagnose and verify that things worked as intended and got it. I first looked at the 2nd hand "serious" market and then decided to go the other way.
Here is my "lab":
Weller magnetic Tempco Soldering Iron (Had several over the time, always lost6/sold them, never broke one, other irons go like shirts)
Good quality all metal PTFE Tip Soldah Suckah
Velleman Digital Pocket 'scope (good enough for 95% of things, for really hard cases I can always borrow something), unfancy but quite effective if you understand what it can do and what not
No Name Pocket Function Generator (Sine, Square, Triangle)
No-Name RLC Meter
No-Name Multimeter
Also a PC with a 24/96 Soundcard with around 100db effective dynamic range and suitable software (Wavelab) as additional Scope, Analyser and Generator up to around 30-40KHz
I find that this covers most things that are not extreme RF or wideband noise. For PSU Line Noise I use a simple add-on that is a low noise wideband amp and single fast rectifier. It allows a reasonable quantification of what happens high up. Usually good enough.
The whole set can probably be assembled for <, $ 1,000 if you shop around.

Sound Technology ST1210
I have one and can attest to its excellent performance. They are mechanically complex and a pain to work on. Getting the oscillator stabiliser to work right isn't easy or obvious but when sorted they work well. The difference from the ST1200 is the higher output and the precision step attenuator. The basic oscillator and notch filter circuit is common to all of them.
For what its worth I have distortion analyzers from 6 different companies.

A filter is such a beautiful thing
about every week or so on of these show up on EBay -- Krohn Hite Filters -- for telcom etc -- this is a KH 3342 -- I would imagine that if you like to test speakers it would be a dandy addition --
sometimes they go for only a few tens of dollars.

An externally hosted image should be here but it was not working when we last tested it.
KH Filters
I have several. They are very useful and accurate. The distortion isn't ultra low but still not an issue and noise isn't bad. Some, like the one pictured, have batteries in them. I need to replace the batteries in two of mine but they don't see that much use.
Getting a handful and "tweaking" them may be an option for a multiamped system. The circuits are all discrete and pretty good out of the box. I'm not sure what the distortion mechanism is, may be a consequence of the filter itself.

Test equipment.
Hi all, I had the fortune of being in the used test equipment business for many years. I had one of the most elaborate benches ever seen. Even had a Solotron 1250 vector analyzer. Several Tek scopes up to 400MHZ. Built all of my own power supplies including 10-16 volt d.c. at 0-120amp continuous. 2.5 kw variac with full Simpson metering. A really neat patch panel for four discrete channels of audio with 8,4,2, ohm 1200 watt loads. Still have a Nakamichi T100 for tape machines. I saw what was going on in the used test equipment market about ten years ago. I sold the Solotron for more money than it cost me to get a good P.C, a National Instuments Multifunction board, and the Labview software to go with it. This can be had cheap on Ebay now. With the exception of the high power stuff. all the other equipment was sold and I now use the p.c. for all my work.
There is a lot of competition for NI now and cards like mine are now less than $400 new! I highly recommend looking at the new generation of p.c. based instruments. Best regards, Steve
