At this point I have 65 firm orders for Peter's book which is about 55 more than I expected when I came up with this bright idea. I am delighted for Peter although I'm going to be very busy mailing

It may be good to rethink and summarize what's going on with these parts. Here's my take on it, presuming I haven't missed something. 1. There is one "good" original J310 that works properly in

Hi Sparky, I have a spare 7D13 I can sell you but I think the shipping from the US will make it impractically expensive. I doubt you will be able to find a 7A42. Those are quite rare. It took me years

A length of wood across the lid to spread the load whilst hammering, moving around the circumference while so doing, then inverting the can to let the remaining paint seal any micro holes to stop the

I don't hammer them anymore and find that merely pressing the lid with my hands or thumbs seats the lid well enough. Besides, a lot of the modern paint "cans" are plastic with a metal rim and lid.

Hi Chuck, That was a fascinating explanation of why the Trinitron was so much better than the shadow mask. I wish I knew this at the time. I would have been able to appreciate the Trinitron monitors

On my probe, the wire broke off right at the connection so soldering it back on only shortened it by less than an 1/8", I thought nothing of the loss, though I did not have the manuals caution to

Try just putting the can with the lid in the right place on a solid flor and stand on it. If it goes right the lid is on securely, if not you have some nice new different-coloured shoes.

Except that they are only about one pixel wide... -Chuck Harris Daveolla wrote:

You could make a nice bug zapper with all those wires, and repurpose its HV supply at the same time! Dave

Ya, I have a handy jar with about 5 or 6 of those paint openers, 2 styles. They work real good. They could make screwdrivers obsolete! Now if they had a gizmo to put the lid back on the paint can it

Or use one of those handy metal thingies from Home Depot to open paint cans if you're here in the States. Doubles as a bottle opener so you can have a cold one while you paint! Don't blame me if

Not quite right to compare 250 to 10Meg and declare 200 to be therefore ok. By that logic, zero ohms should be just fine, too. Yet, Tek went to the trouble to use resistance wire. Clearly there's a

As I've said a couple of times, that circuit is very tolerant of FET parameters. It was designed to avoid the expense of matched FETs, so I very much doubt that any selection was involved here. Are

No, I did not do a YouTube video. But I've seen one out there. I didn't have a replacement cable or other parts. I cut my cable off at both ends as close as I could to the strain-relief parts, then
