    0-30 Vdc Stabilized Power Supply

    Now seriously, i start building electronic things back in 1984 ...+- 1 year...  The computer is a normal way to do it now but when i am in a hurry i prefer the paper. I'm more used to it.

    0-30 Vdc Stabilized Power Supply

    Did Romania tell you something ?  :) :) :) So, how about a ( toroid ) 18V / 75VA trafo ?  ( 2*18V / 150VA for a dual power suply - i allready have this one ). I dont mind if the maximum voltage will be a little less then 24-30 V.

    Thanks Audioguru ! But i was triyng to replace the ops with cheaper versions because, for a dual suply the costs of the entire project will be very close (or beyond) to a "store ready made" suply 0-30V/0-3A. If i replace 081 with LM 301 (with compensator caps) will there be a problem ? Or maybe...

    Just wondering if these could be replacements for TL081 : OP07C NE5523 MC1558 LM118-218-318 RM4558 LM301 UA748 And if yes what are the adjustments (trimmer, bypass caps etc.) By the way, with the original specs the power suply work great. Thanks in advance! op-amps.zip
