what can i use these for- 1973 chips

[jimbob]

I recently recovered these from a slaughtered Hammond organ that worked but had been in an accident involved with a staircase. Anyways,
found these chips among the variety of other things- i tried to find info out there on google and no luck. I was hoping anyone else may know something.

1. 18252  ro72147   102000

2. i302   ro72147    101

3. npc 47298

4. sprague 7233   us 7472a

Thats all the info i have.

thanks for any help

I can only suggest that you find a Hammond Organ forum if there is such a thing and ask them.  You never know they may be sought after like the old Ge trannies are around here!
