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. mnem*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 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.

Quote from: Ice-Tea on January 26, 2021, 02:32:55 pmHmmm.. 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. They are apparently good for testing the resilience of radio gear against jamming amongst many other things.

I'm wondering: where do you buy those nice yellow protectors?

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.

Today's Lesson: never trust HR.
Fairly obvious that one
Quote from: factory on January 25, 2021, 12:51:02 pmAlso 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. DavidGood 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. mnem*toddles off to be... parental*

From experience what they advertise is never in stock.Also don’t forget +delivery (usually around 20-25) then VAT.

Here's a couple for you to fix and flip bd:https://www.ebay.co.uk/itm/Tektronix-TDS-3014B-100Mz-1-25-GS-s-4ch-DPO-Faulty-Spares-or-Repair/164665558055https://www.ebay.co.uk/itm/Tektronix-2430A-150-MHz-Digital-Storage-Oscilloscope/114651847082

Don't fancy the risk. CCD fail on the 2430 means finding unobtainium ICs. The 3014B is probably hosed flash or motherboard at which point forget it. No schematics available and I CBA to reverse engineer it. I'm lazy and I know when I'm going to be defeated
