2215A focus resistors
I looked at the Ohmite catalog that I have and it looks OK. I am sure, you noted that OF series is rated 300 Vdc, so whether using two resistors to drop voltage load to half is going to give you anyth

Do not forget, getting high frequency plugs, like 7A29, for your 7104 would get you few extra bragging points at the bar, but you do not have to do that to get your money worth out of a 7104. It takes

Ruminations on current Tek Scopes...
That is sad to hear, but I guess everyone has a breaking point and can not be blamed when snaps. As for crashing when executing complex things, I guess, all of us users are to share blame: when instru

Not quite so, Craig. The IRC, a stable mate of Welvyn, is offering carbon composition as IBT series in their catalog of unspecified date, I would guess late 90s. Those might be somewhat cheaper than W

454 Intensity Problem - help? - a little more detail...
Now, Don, it does not need to be ham-fisted removal, all it takes is to look at the damn things crossly and they fracture. Several cap manufacturers would not warranty parts if they are hand soldered

Hello Denis, Please, elaborate on this compatibility between 7K and 11K as much as you can and then some more. Does your sentence part '- this rolls them to a -10' mean '10K is a hybrid which works in

454 Intensity Problem - help? - a little more detail...
Leaching silver from capacitor ink or end-caps might have been a problem 15 years ago, but for long time, anyone who is significant in component manufacturing is putting a nickel barrier over end caps

Hello Michael, Consider 7104, it also uses MCP as 2467and does not have bad reputation for hybrids (it was manufactured in hay days of Tektronix). Lately, it's price seems to have dropped considerably

OK Stefan, Whatever you say. I did not expect 'ESR Meter' to have 100% coverage, because nothing does. Calling it ESR tester does not change anything for me, meter or tester. Intended and advertised p

2215A repair question, carbon composition resistors
Hello Didier, Now that you told us about good sides of carbon composition resistors, I was wondering what is your evaluation of modern days version of those resistors. A bad reputation for high drift

Now, Don, that is an unseemly expectation, for mere $49 you want an instrument that would distinguish between a near DC short and low ESR. Some people seem to treat those ESR meters as a silver bullet
