what are these?
 

looks like 2 different versions of same component.
most likely the newer one has the 2 piece pigtail and built in mount.

Some kind of rectifier?
(thing with fins is a heat sink?)


:confused:

Maybe an amplifier for a tape deck??

"Bill"!

I believe I saw Delco stamped somewhere but will go back and look again

I believe you have a stereo heat sink for late 60's AC Delco stereo radios.
Some vehicles (1968 A body Pontiac, First-gen F body, Second-gen Corvette, etc.) used a remotely mounted amplifier.
Here's a picture of a similar (mono) heat sink. This one is for a 1967 Firebird AM-FM radio.
Attachment 625509

that heat sink is common.
I have the 67-8 Firebird stereo and it uses nothing like this

Early transistorized ignition? If not Delco than aftermarket? Some early stuff used transistors to switch the coil; the points were used to control the transistors... seems like too many wires for that purpose tho.

I have an NOS TI unit for sale and it looks nothing like this.
I think the key will be the wiring harness connector.

George heres what the TI control unit looks like

Do you have an electric scooter? Possibly a control unit for that. Also possibly a rectifier regulator for a boat or motorcycle, but usually there will be 3 wires of the same color and a different type of plug.

I recall seeing an aftermarket "transistorized ignition" unit back in the day built on a similar heat sink, and also recall only a single transistor, kind of the stuff you would find in the JC Whitney catalog.

Our 63 GP had TI and something flaked out on it so Dad built a Heathkit unit and ran with that.
Im certain this isnt that.
