Heh - me too. In my case it was a EE1050 (IIRC) base kit, then a pair of add-on kits (EE1051/2? can't remember). This was around '67-'69. The transistors were silicon, though (BC148 etc, IIRC).

Then you must be younger than I am. Mine contained two AC127 and there was one steel heat sink in the kit that could be slipped onto one of them by bending it open a bit. It snugged back on like a spring and looked like it gave the AC127 wings. Like with aircraft you could select "high wing" or "low wing". I preferred low wing. There was an AF126 with very fragile wires. Had to be treated like a jewel because it cost >$3 at the TV repair places. This was my opening crescendo into the world of RF. You could (almost) get it into the VHF range. But then I discovered that tubes from the UHF tuners of discarded TV sets were the bettter deal, a.k.a. free. Of course, these needed a very different voltage level on the plates...

With the EE-1050 etc, the transistors were premounted - the BC148 etc had very short pins...

Yes, I see your transistors. The template idea was carried through to the later kits.

Heh - they were (are?) excellent for lighting up bulbs with no wiring - one could just wedge a bulb between the two prongs... Steve http://www.fivetrees.com

In the UK they were known as 'flat' batteries - not because they held little energy but because they were physically flat and suitable for slim torches. Steve was right about the spring contacts though, many a battery was sacrificed because little care was taken in keeping them separate and after a few minutes of touching they really were flat! I think their part# was 1216 or maybe 1219. -- Graham W http://www.gcw.org.uk/ PGM-FI page updated, Graphics Tutorial WIMBORNE http://www.wessex-astro.org.uk/ Wessex Astro Society's Website Dorset UK Info, Meeting Dates, Sites & Maps Change 'news' to 'sewn' in my Reply address to avoid my spam filter.

That's what the "fancy" kits had in my days, made by Kosmos. I never warmed up to that idea because I wanted to work with "real" parts. Shortly thereafter, I believe at the crisp age of about 10, I scraped all my allowance money and bought a solder iron and some solder. In hindsight a rather dangerous thing, no grounded plug and all. The solder was more for plumbing work but what did I know? I guess my parents where unaware of this exercise and how dangerous it could be but in the end it helped me in learing how to solder. Don't blame my parents, I hadn't told them about the solder iron purchase.

The really nasty surprise came when you did that but didn't discover it until weeks or months later. By then many of these had oozed all over the place. -- Regards, Joerg http://www.analogconsultants.com

I can't even remember using that battery now. If you'd asked I'd have said it used a 6V 'lantern' battery. Graham

The EE1050 etc used a battery holder containing regular 1.5V batteries (AA types, I think). Six of them, so 9V total. Steve http://www.fivetrees.com

I had the opposite experience. I grew up with ungrounded soldering irons, with tips that were isolated from both hot and neutral (they had to be, with no polarizing plug, I guess). Thus I had the expectation that I could solder live AC and DC wiring inside my radios with no problems at all (as long as I was holding the solder by the plastic reel. That ought to place the time pretty well: before grounded plugs, but shortly after solder stopped coming on metal reels.) THEN I bought my first Weller with a grounded tip and made a circuit between AC hot and the soldering iron tip via about 6" of solder, and wowee-kablamoo, 6 inches of solder turned into a bright blue spark and disappeared into vapor that I probably inhaled when I decided to start breathing again (maybe a minute later). There went that bad habit! Tim.

IIRC the EE20 instructions or a note inside the German version stated another battery that could be used. A lantern battery but those were so outrageously expensive that nobody used them even in lanterns.

That decidedly puts your Philips kit into the "new age" category :-) -- Regards, Joerg http://www.analogconsultants.com

Yes! I just got off the phone with a very nice guy at NXP. Actually it was very hard to get him /on/ the phone in the first place. All I need are some jellybean parts that are sold only by the 3000pc-reel by European distributors. So I wanted some samples. As I'm working at the University in Hamburg, the first number I tried was the Hamburg sales office. Tried 5 times and never even got a ringtone. Next was Frankfurt. Got someone on the phone, but whenever she tried to get me through to someone we were disconnected (I tried this 3 times, each time got a different switchboard person who failed in the same manner). OK, Munich. Very friendly people told me that the person in charge for people "like me" (academics) was on vacation but back next week. So I talked to him. He's going to get me samples, no problem. I asked him why the standard distributors aren't carrying these parts in small quantity, and why getting sample was so hard. Boy did I open up a can of worms. Essentially he told me all that you wrote in this post, including naming American mfgrs that are doing it the right way. I asked him how NXP expected to get designed-in when it was so hard to get your hand on their products. He said he didn't know. I asked him to maybe raise the point with someone in charge. He said he'd long stopped doing that. I said that the people making $$$ purchase decisions were at one point little engineers, scientists or hobbyists. He said he knew. Since we had agreed on pretty much everything it seemed we might as well end the conversation, which we did.

I'd love seeing that happen to someone at NXP or INfineon.

The stuff that I want is actually in stock at DigiKey. Nothing exotic. But ordering at DK from a German government office is a big hassle because they don't have a German sales office. The easiest method is going through my private credit card and getting reimbursed after a lot of red-taping. Besides, DK is generally more expensive than European distributors so it doesn't make sense to place a large order which, among some DK-only parts, contains stuff that could have been purchased locally.
> >>>I made a final decision today to not bother looking for their parts any > >>>more - there's nothing they have I can't get elsewhere,
Well, I always wanted to try out their BF862 and the PMBFJ620 dual (hoping to replace those expensive TO78 parts). The 620's datasheet is complete crap of course. Just a few "typical values" curves that look like someone had jotted them down in a few seconds using log-log paper and a ruler. And nothing, not even a hint, as to what kind of matching I might expect. But cheap (if you want a 3000 reel).
