How many times has the digital scope lied to you because the glitch you were looking for was between samples? Glenn

In the 75 Ohm vs 50 Ohm world, the two are completely interchangeable as far as mating is concerned. The 75 Ohm BNC connector is missing dielectric between the center pin and the shield. Based on this

I got mine today and they look great. Glenn

I offered $10,, with note it front panel not destroyed would give $200.00 to show that the destruction cost him. Glenn

Here is the MSDS for Selenium Oxide. https://www.fishersci.com/store/msds?partNumber=AC193980100&productDescription=SELENIUM%28IV%29+OXIDE+99.9+10GR&vendorId=VN00032119&countryCode=US&language=en The

If the part is beyond repair due to parts not being available and redesign being too costly, the repurpose of the item to aid in the repair of other equipment that can be repaired should be encouraged

I received my book today in Goose Creek, SC. Thank you very much for your time and efforts in making this happen. It arrived in great shape. 73 Glenn WB4UIV

You can try MEK, methyl ethyl keytone. It will dissolve a lot of epoxies. Be careful to not dissolve other things. 73 Glenn WB4UIV

That is the part. Thanks Glenn

Thanks for the help. I had not seen that coding before. A very good day. I learned something. Glenn

I have a battery BMS that I am reverse engineering. I have a resistor with a code that I have never seen and cannot find any information on. The resistor is a SMT device marked 4L0. The L appears to b

Me too. Glenn

The carbon comp can absorb much more transient energy than a film resistor. The carbon comp is a mass with leads on it, the film is a film deposited on an insulator, much less mass to absorb transient

Mine does not work. Glenn

My first 453 had no trace. The fault was a 500 pF filter capacitor on the HV line. The capacitor was a red, possibly epoxy, encased capacitor. When held up to the light you could see black arc marks i

From what I can find about carbon composition resistors, the resistive element is a composite of finely ground carbon granules and a binder. The amount of carbon granules in the binder determines the

If it was in use at a TV station, the CRT is probably shot. The only use that I know of for this specialized scope is to monitor analog video to set levels and for signal verification. It has use in a

Baking the resistor will only fix it for the short term. It will absorb moisture again as you have not fixed the problem, only the symptom. There is a crack or 0r other point of moisture incursion in

It appears a BNC T adapter, two equal lengths is 50 Ohm coax and another 50 Ohm coax would create a dual input cable to serve this need. Glenn
