Can't help with the MC's, however, the MPSH17's cross to NTE/ECG 229 and the
2N4417 is an NTE/ECG 452.
NTE and ECG replacement parts are very common just about anywhere. Your
local jobber will have them.
I have a hunch that the MC parts could be rounded up with a more exhausting
computer search.

Hi,

I am trying to locate some obsolete components.
After the usual google searches and numerous emails to vendors, I am
hoping
someone here will have what I need.

I need 2 ea MPSH17's, 1 ea 2n4417, 1 ea MC145152 and 1 ea MC12017.

If anyone can help it would be greatly appreciated.

Ed
