Another of my not-quite-off-topic posts about the Soviet plugin scope series that was clearly inspired by the Tek 7k series. Having started investigating this stuff, I'm now playing a sort of plugin

For quite some time, large plastic parts often have had the plastic type identified with a stamp built into the molding dies. I don't know if this was common back then, but you can try looking around

I have used methylene chloride (dichloromethane) very successfully on 1502 cases. I've repaired both hairline cracks and 1" bits chipped/broken off without problems. Be careful, since it is an

I had one of the cases repaired by a person who uses plastic welding and it turned out bad. He wasn't sure what the material was. Looking inside the case I can see some type of dark glue that attached

Thanks to all who responded to my problem. Some didn't know that my email server is YAHOO, and mentioned only groups.io. When we do a round table discussion the original message gets lost. I no longer

There's a local Rat Shack, but apparently this (and most) are all franchise stores, carrying branded stuff, but not just that. Normally don't need to go there. Harvey

Hope this appropriate ... FYI I received this just moments ago ... Hobbyist? Maker? Do-It-Yourselfer? Announcing over 60 new RadioShack Express HobbyTown stores stocked with everything you need to

I only lifted a couple pads, out of thousands. The ones that did lift were on very low grade consumer products. I agree that there are better methods available today, but what else was available to

Radio Shack is NOT gone ... Just wanted to let all know: check listing in your area: also they have other companies selling their items much like Sears did. Joel

John, Your notes of 21 May 04 actually show the switch configuration that works for me. However, with several conflicting publications re this, I wasn't sure who to believe. Now I know who to believe!

There are, indeed, many cheap/fast PCB suppliers. Most won't "advertise" /other/ people's boards, nor allow you to buy them. If I was to make such a board, I couldn't be bothered with all the hassle

When I designed the board, I intentionally made it one-sided to eliminate the exposure of the higher voltages to the top side of the board. In retrospect, those would be very difficult to get one's

Hi Reginald, Have you taken a look at the tremendous collection of stuff on Hakanh's site? There is a semiconductor workbook at http://hakanh.com/dl/kits.htm (bottom of the page, more or less) which

Hi Tom, I've used them before. I used JLCPCB for these boards. I'm pretty sure there are several options for inexpensive boards like these. Thanks, Barry - N4BUQ

Alternative: use http://dirtypcbs.com/store/pcbs# You can make the design available for anyone else to order: http://dirtypcbs.com/store/designer/pcbs That saves you hassle and you are given some

I may do that. If someone wants just one, then it's somewhat cheaper to get it from someone (me?) who orders a batch. I'm probably going to order one more batch with the updates I mentioned and then

Barry, Although I'm not interested in these PCBs per se, could I make a suggestion? Perhaps for international Tek fans you could put the design (schematic, layout, & gerbers) on github, dropbox, or

I'm well aware of the site. But I had not found a substitution list on it. All a search with google produced was quotations from manuals about checking by substitution. But I did find the Tek cross

I started working in a TV shop at 13, in 1965. One older tech was a fountain of practical knowledge. I wasn't old enough to open an account at the local parts house, so he would buy things for me so
