As a senior manufacturing engineer, my job was to keep stuff running while innovating for constant manufacturing cost decreases. Came from a poor background and a single Mom, never had all the stuff kids have today. But I didn't know I was poor. Always made things and fixed items that broke...
shrtnd: Again thanks. Checked e-bay and purchased new old stock in box with manual for $21.00. I had been looking on e-bay and this showed up today. thanks... Tom
shrtnd: Thank you for your comments. I have looked about everywhere I could think of on the internet and have found nothing. Interesting about the new old units you found and I hadn't thought of that. Might give that some thought and take you up on the idea. Thank you for responding. Never...
Gentlemen. Thank you for responding...
AS SHOWN BY "B" - I have 4 home built regulated power supplies. Two were recently completed with the LM338 fed by a 4 amp 12vac transformers.. Running engines on an 0-scale model railroad, even multiple headed, the maximun current read 1.5 amps with...
Just having built two 0-13V regulated power supplies and having excellent results with the LM338 regulator, I need to upgrade two older units built with the LM317 in order to get more than 1 amp of output.
I have a question on the proper placement of the Ammeter. I understand that the ammeter...
Gentlemen:
I have a Phillips PM3335 Scope that has a blown miniature reticle illumination lamp. The number of the existing lamp is M6628V 80Ma. There are lamps on e-bay that look the same, are 28volts but are rated at .04 Amps. I see others from various sources that have ratings of 1 Amp...
Some very helpful information here. If the below doesn't mean anything to anyone here, I will try the Power resistor technique..Thank you.
However: Removed the transformer from the enclosure and found this: LEI Logo in a circle, and 60LEIB-002?
Anyone?
I have the switch located on the hot line, the one with the Hot oriented prong plug. The schematic is not drawn correctly, as I referred to in my first response but not precisely communicated.
Sorry, a little confused here. My fuse is connected to the mains hot line via a non reversible 110 volt plug. If the fuse blows, the hot line is disconnected. Can you show me a schematic of what you are describing as a better way to be safe? Thank you... Tom
