Greetings To All Just for the members of the group and as just recently I have finished ( supposedly ) our website update I am pleased to offer a 12% discount for any purchases site wide For those

I acquired a 549 in very good condition about 23 years ago, used it for three years and then had to store it away. Storage conditions were humid but not damp during summer, bone dry in winter. It was

Channel 2 likely has something unbalanced. Ground the input and put the position control at mid point. Go through and look at the collectors of the transistors in the amplifiers (or the outputs of

The folks interested in 7603's were not interested in fedex ground rates of $1.33 to FL and $1.15 from Austin to Dallas, so maybe two whole 7603s with big CRTS serial B370900 and B370786 are going to

Yes both, but is only a serial filter, it should work shorted Regards! -----Mensaje original----- De: [email protected] [mailto:[email protected]] En nombre de zenith5106 Enviado el: martes, 25

Hi Guys, This group is really amazing.... Can't possibly quote each of your answers, but I`ll summarize. @Jim... I didn't really check the capacitors and the diodes that exist on the 7A13 circuits

Bert, I also would love just to pick new ones and throw them to my shopping cart of DigiKey...And yep, there seem to be quite some options that can be used using (with an adaptor board). But I`m not

There is some info at Tekwiki, which is maybe where you saw the substitution info: http://w140.com/tekwiki/wiki/Miniature_relays Colin.

Hi, It's a 222 . Szabolcs Miguel Work <harrimansat@...> ezt írta (id?pont: 2018. szept. 25., Ke 19:45):

Fabio, The relay exerciser I built was very different and based on 4000 series CMOS with a 4060 oscillator/divider and a 4049 to drive the relay. I believe the 4049 has protection diodes to clamp

Take a look at https://www.youtube.com/watch?v=mjF0S-ctXfg as well - shows a relay test with a scope in X-Y mode. Best Peter

Latest info : I have now replaced the timing board with one from the parts-donor. This hasn't solved the problem, so I'm scratching my head again, because the behaviour of the "A INTEN" and "B DLYD"

Adding extra caps is certainly unnecessary, and most probably not a good idea. It defeats what you are trying to achieve. The whole purpose behind adding a cap across the relay coil, or adding a

Hi Is 222 or a 222A? -----Mensaje original----- De: [email protected] [mailto:[email protected]] En nombre de Szabolcs Szigeti Enviado el: martes, 25 de septiembre de 2018 19:20 Para:

Hi, I have made a battery pack for my 222, but interestingly it does not work. It works fine from external power, but not from battery. Closer inspection showed SMD inductors L309 open with burn

Fabio, I was going to ask if you had checked the filter(blocking) diode across the relay coil and also the filter cap with the diode? Where I used to work we had an older CNC lathe a "Tree" brand with

Fabio, It would be nice if we could find a replacement for these, even if an adapter board was needed. I worry about this just about every time I use my 7A13 so I end up using my 7A18 ( with the
