Recently, the biggest styling change for new cars have been the introduction of enormous brand badges...  have you seen how big some of the recent Mercedes, VW, Mazda, etc., badges have become on the front of the car?

I guess it's a hard life as a stylist, when all the cars are designed in a wind tunnel and look the same, the only thing you can do to differentiate is the GIANT BADGE on the front (since nobody would be able to tell the difference to another marque without this aid)!  :D
One thing I do love about today's cars are the LED side and rear lights and how some brands have gone for some very distinctive shapes in them and how nice they look at night all lit up, reminds of how BMW had their angel eyes around their headlights.

Hmmm.. This on the bench. Nice bit of kit but complex. In addition, not sure if it's worth much. So I'm considering either tossing it on the Bay untested or have one you folks have a go at it.

So, how about it? Anyone interested in spending some quality time with it? For fun, for review, whatever. No strings attached, no obligations. I'm paying for shipping (inside the EU that is...)

I got one of these, picked it up for next to nothing still with valid calibration, well valid until a month or two after I got it.
It's still sitting here after many months and I haven't even turned it on. :D

They are apparently good for testing the resilience of radio gear against jamming amongst many other things.
Any circuit design must contain at least one part which is obsolete, two parts which are unobtainable, and three parts which are still under development.

PowerGlide & TH400 both responded well to a few simple performance building tricks; aftermarket parts were very well-developed for both when I was just a kid. The PowerGlide was actually pretty grenade-proof, and properly modded with high-stall TC and HD clutch-paks/bands, was a favorite at the drag-strip for over a decade.

The TH400 was designed from the ground up for Olds, Pontiac & Cadillac's "too-fukkin' big big-blocks" that all delivered stump-pulling torque at low RPMs; bone-stock they were tougher than leather and with the addition of higher pressure regulator and accumulator springs, would deliver shifts so solid they'd snap your neck.

I loved the one I had in my grand-dad's F-150 shoehorned in behind a '70 Cadd-500; even with 3.00 rearend gears from the original OD trans, that thing just jumped forward when it shifted gears. Also, I had a micro-pushbutton embedded in the shifter T-handle to engage the kickdown solenoid when I wanted it.  >:D

*sigh*

Any idea why the old Powerglides had that distinctive whine or howl when you put them in Park?
Sounds to me like it was just the oil in the torque convertor swirling around under pressure.

If that's the case then I would have expected it to make the same noise when in gear. It doesn't. The whine stops are soon as put in gear.

The difference is backpressure. In PARK the pump is running in bypass mode; this makes the noise from a worn pump and air bubbles much more noticeable. As soon as you put it in gear, it is running under load with considerable backpressure.

Switching to Type F, DexronII or Trick Shift in most cases made this whine go away completely or almost completely.

mnem
 :popcorn:
Yep, that was my thinking as my Vanden Plas 3 Litre had a fluid flywheel / torque convertor and that also exhibited similar noises in PARK position. Like the photo only mine was all black and had been chauffeur driven all its life till I brought it.

You have the original AA badge too! My father drives a Nissan Qashqai with that badge on the front too (looks a bit out of place), but he's welded it inside the car to hopefully stop someone stealing it.

Yes, I skimmed over the manual - it's a test set for said special purpose, with some interesting internal details. Alas, as often with specialized test sets, not very useful for other tasks than the intended one.

Not just another pretty face. Larry has a new look. Broken knobs replaced, sticky push button switches lubed, numerous sticker residues removed, and general spit and polish. This 485 has led a rough life and was ape handled by multiple Gorillas.  :o



Next on the agenda. Line cord needs some attention and then pull the rear panel and find out what the fan is rubbing against. Stay tuned.

Cool, thanks!

Wow that was real quick, I listed a Solartron 7150 Plus yesterday on the bay and it has already been snapped up, perhaps I undersold it, listed it at £110 BIN and there are 3 others (but the Plus model) up for sale at £70 each BIN for parts/repair. Something tells me that I undersold it, oh well, its done now.  :palm:

You can get a 7150 Plus from a dealer for £90 inc VAT  :-DD

Or you might prefer their hp34401a for £275-325 :) That's lower than many of the prices I've seen at the Ramco auctions.
There are lies, damned lies, statistics - and ADC/DAC specs.

From experience what they advertise is never in stock.

Also don’t forget +delivery (usually around 20-25) then VAT.

Yes very obvious (mentioned on another forum only couple of days ago on a wanted post), but I don't think I've ever bought anything from them.

Also have something much older and more unusual from a local seller, a GEC Resistance & Capacity Bridge, can't find much about this one at all, it does mention using Selectest for measuring leakage current but doesn't mention if it was made by them, possibly much less common than the Hunts ones.
   David

Good for you! I hope you love it as much as I do my 54645A! The only downside I could see from the spec sheet is the small 5K memory depth; OTOH, sampling at that kind of speed probably did hit a number of brick walls in terms of just what could be done using current tech without bending the laws of physics. Or becoming a money-sink the size of the national debt. ;)

That bridge does interest me quite a bit; it reminds me very much of a cap analyzer I used to own. Hope you can get it working; I've always had a soft spot in my heart for those tuning-eye tubes.  ;D

mnem
*toddles off to be... parental*

Some more pictures of the GEC Resistance & Capacity Bridge, I'm currently replacing some of the capacitors and plan to add a fuse inside as this seems to predate safety.  :o







Lots of war surplus parts in this, the two block capacitors test OK, but most others are now nice resistors.


What's this strange F marking on this capacitor.  :-DD

My £90 includes Vat on £75. Postage varies. This is the current ad not the stock lists.

I've bought from them for over 30 years, personally and for work and never had any issues. Not had much from hem recently though.

Yeh, I know, I have had it confirmed that it was the place that I thought it was, special offer, as tested, no leads etc and more than likely still with the old time bomb intact etc etc.

No pictures but rear panel was removed from Larry and the fan was hitting the grille. Reason: slightly bent rear panel. Fix: Friendly persuasion with some well placed blows with a BFH took care of the problem. Fan now silent. New strain relief installed on line cord which is a real challenge to get seated when you don't have the proper strain relief install tool. But it's finally done and secure. The line cord is also separating from the plug. Don't have a replacement plug handy. I'll have to get one from the local home center.

Tomorrow start on the functional issues...which at first glance appear to be quite a few. But the first and overwhelming issue is the fixed maximum intensity on the CRT. I have a suspicion that the CRT itself might have an internal short. But we'll see. I do have a spare CRT so no worries if it is duff.

That's it for today.
