Re: Shipping Scopes
When double boxing, I always assume that the outer box will be sacrificial.? The inner box should be well fitted to prevent movement and should be good enough to almost ship the scope by itself.? The outer box absorbs all the impacts, so I tend to use softer materials, and leave voids at the box corners (not edges).??

A few weeks ago, I dropped off a box at Fedex and asked if they could slap on some "fragile" stickers.? I was told they could, but it would only help during the initial load onto a truck, and final delivery.? Everything else "would be handled by robots that can't read".?? -Dave On Wednesday, September 23, 2020, 11:06:12 AM PDT, ken chalfant <kpchalfant@...> wrote:

Re: Shipping Scopes
My favorite is polyethylene foam planking, but there are different densities and finding a reliable source of used material can be difficult.

Re: Shipping Scopes
If I can, I pack items myself and take them to UPS or FedEx for shipping.
Double-wall boxes are available at Home Depot and Lowes. They are usually in the ¡°moving supplies¡± aisle. If you are shipping a scope with plug-ins, remove the plug-ins and pack them in a separate box. It may be more expensive, but my understanding is that Tek always recommended shipping scopes with the plug-ins removed. Besides less stress on the backplane connectors, packing the plug-ins separately means you can pack them to better protect the knobs. I probably overdo packing and it costs more both for the packing materials and higher shipping weight but if you want an item to get to its destination in good shape, pack well. UPS used to say to pack for a four-foot drop onto concrete (a sign in the UPS store I used to use when I was in Los Angeles and bought a lot of surplus electronic equipment). Nothing I packed and sent home was ever damaged in shipping. I bubble wrap the scope with at least a double layer over the front and back. I buy the inexpensive white styrofoam insulation at the home improvement stores. I have found that using a serrated knife works well (I bought an inexpensive bread knife for this) to cut the foam to fit the box. I will usually put an extra couple of layers of bubble under the bottom of the scope. I always attach a label with the address of the recipient on it to the wrapped scope or other item. If there are voids between the wrapped scope and the foam lining, I fill that with more bubble. I hate using styrofoam peanuts to fill voids, but there¡¯s a trick I use so the recipient does not spend a mess of time getting the peanuts out of the equipment or off the floor. I put the styro peanuts into plastic bags (I use recyclable grocery bags for this) and tie the bags off so the peanuts stay in them. Sometimes, I put an empty bag in the voids if they are irregular in shape and then pack the peanuts into them and tie them off. Loose peanuts also ¡°migrate¡± in the box and putting them in bags prevents this. A couple of other tricks. Stretch wrap - I use that to hold the bubble around the scope rather than taping it. It allows the bubble to be re-used rather than thrown out. I have also used painter¡¯s tape (¡°blue tape¡±) for this as it is easily removable so also allows the bubble to be reused. I tape the box shut with packing tape including the edges of the flaps (keeps them from getting caught on the various sorting machines). I put the label on the ¡°top¡± side as that tends to stay right side up. Another trick - write on the BOTTOM of the box - ¡°This side DOWN¡±. The reason? If you write ¡°This side UP¡± on the top and the box is inverted, the shipper will not see that. If it is bottom up, then the message that it is inverted is clear. For really heavy items (not heavy enough for freight) I staple the carton. Years ago, I bought a carton stapler and a box of staples. I still am using that first box of staples, but I still have it - only about a quarter used.

Re: Shipping Scopes
My favorite source of boxes for shipping large/heavy items are bike shops.? Of course, they need to be resized, but with foam planking and double boxes I never had any damage shipping scopes.

Re: Looking for calculator keyboard for 7854
I have no idea how they lost it, but apparently it's not unusual for the GSP to lose packages; apparently it arrived in the UK and the courier is still waiting for it (a month since it got to the UK). Ity will probably turn up in a lost items auction and end up back on ebay or being tossed in the rubbish bin

Re: Shipping Scopes
Fedex and UPS pack things fairly well, I have not had any damage. It can be pricey, but is usually less then traveling to pick something up. Some people offering equipment demand that you pick it up from them. I have accounts with both Fedex and UPS, that allows me to take care of everything from my end and convince reluctant sellers to take items to the stores. I ask everyone who demands pickup only to reconsider and be willing to take the item to a shipper who will take care of the packing and shipping.

inches of loose padding all round for shock. I have gotten them double boxes before and a 576 even in a wooden crate the trick is limiting movement in the box I double boxed a high end computer it made it safely to California from the east side. But it was not cheap to ship. I have also been successful crating things and shipping them freight. Plywood and padding is wonder for protecting the device.

Re: Shipping Scopes
Depending on how many boxes you need check out Uline.? They have double wall boxes of all sizes.? Staples have some boxes that are better than the Amazon boxes.??

Re: Is my Tek 468 beyond repair?
Replacement 5V crystal arrived today. Extremely fast dispatch but its output is only 1.2Vpp and nowhere near the expected TTL level!
I modeled satbegginers idea in LTSpice but couldn't get it to work properly. The output was barely above zero. Scm's idea works well enough though provided NPN collector goes to Vcc and PNP collector goes to ground! I used 2N2222 for the NPN (transition frequency=250MHz) and 2N2907 for the PNP (transition frequency=200MHz). |

Re: 7623A Storage problem
Colin,
I had the afterthought about low voltages since the regulation of the power transistor Q1195 relies on +5V, +15V and +130V being OK. The components I mentioned are all on the low voltage side of the transformer T1199 and can be checked with the power off. Q1195 is attached by a plug and socket so it can effectively be tested out of circuit, Q1190 can be checked as a pair of diodes for open circuit / short circuit. The two capacitors are likely to be short circuit if they have failed and L1198 will be open circuit if the fuse didn't do its job in time. At least you don't have to wait 30 minutes for the high voltage to leak away! Regards, Roger |
