There are many training cources on ebay a lot cheeper than thru catalogs and I was told to learn is to build on bread boards and kits.

Where does someone go without info about equipment bought used lab type with no manuel ?
1 Power supply bought used 30vdc @ 5a.
2 I have to donate to any one who needs on a Tektronicx model # 7854 on my adobe if any body needs a 90.00 manual for free plus the posibilities of oter tecktronix manuals web site # but dont know where to post.

I need assistance with two transistors and info if data sheets are available.
1. MJE3055 Data sheet and MJE3055T Data sheet to see if they are interchangeable.
2. MJE2955 Data sheet and MJE2955T Data sheet to see if they are interchangeable.
One other part a IC
1. L165 DATA sheet and L165H Data sheet to see if they are interchangeable.

go to http;/users.otenet for a 65watt class A amplifier and search for link to Sams
Electronics Web site ass agood site if you enjoy web site in Australia.

Can any body help a newbi to electronics with a clarification. I researched a part #
IRF9540 with Digi key and got the result of  manufacture part # IRF9540NPBF. how do tellif it will work as i have the sme problem with other transistors pluss TL084
OPAMPS. The letters at the und make me unsure weather to buy them or not and search for exact numbers.

To your question what does the MK50250N do In the book Integrated Circuit Projects
By Carl J. Bergquist there is a circuit for a alarm clock with all parts plus a speaker. The part in question does most of the work and drives a hex driver plus two quad segement drivers which drives the 7 segement dislay. Any ideas as to where to purchase or where to post the quere is appreciated plus data sheet. tanks kbyrne

  kbyrne the MK5025ON is a ic the rest of the parts are transistors and I have a hard time  with BC & BD numbers as to finding them except a NTE replacement number. My question is an a strictly Class A Amplifier will a NTE brand transistor work out for a BD
transistor or a BC transistor as long as the legs are accounted for.

New to electronics hobbiest needs help finding obsolete parts as my supliers cannot handle some parts. parts needed are in small quanties only.
1. MN3001 @ 2 pieces.  2. MK5025ON  @ 1 piece.  3. BC184L @ 6 pieces  4. BC214L
These parts are just a start as there are others for projects.
