Just a note... any of the 723 based regulated supplies can use some
bypassing on any of the pins that connect to the Internal Zener diodes
within the IC... I use a .01 uf @ 50 Vdc... for tough cases where a lot
of background noise is generated by the Zeners , I double up with a .1
uf @ 50vdc as well... not having the IC diagram in front of me, I cannot
tell you which pins require bypassing...it CAN make a huge difference to
the noise floor of your rig, and it is especially obvious on VHF and up
gear where the noise floor is of extreme imporance... 73 de Jordan...
