TI amplifier finish

[Robert M.]

My 67 original TI amplifier needs refinished. Were they originally gloss or flat black? Thanks

Gloss black

Re: TI amplifier finish

The '67 Judging Guide just states that amplifiers are painted black, doesn't clarify gloss-semi-flat etc. The original TI amps that I have seen have all been gloss black, including the one in my car.

Isn't the base plated gold color?

Yes, my reply referenced the housing only (black) not the base plate which is a separate piece. Thanks, I should have clarified that.

Re: TI amplifier finish

Thanks all for refreshing my old memory. I will pull mine and refinish it in gloss black. The electonics ae all freshly redone.

Re: TI amplifier finish

The amp housing was painted semi-gloss black (slightly glossier than the distributors, but not nearly as glossy as we know gloss to be today), then the mounting hole was machined the size of a flat washer at the three mounting ears (this is necessary to insure a good ground, so if you are not planning on re-machining; place a flat washer centered over the holes as a mask). The backing plate was dychromate (not gold painted), as were the attaching screws. The Delco decal was applied up-side down (as seen when the housing is mounted)-I have to assume so it could be read more easily when the unit was installed.
We recommend media blasting all the brass terminals to insure the best connection possible and a little dyelectric grease in the terminal boot. Also, media blast the inside of the housing to insure your new module has a sufficient ground.
Restoring these amps is one of our specialties and do many per year; so, information is from GM blue prints and experience of seeing hundreds of original amps.

Re: TI amplifier finish

Mike I've seen your restorations of the TI items and you do outstanding work.

I played around a little bit with my first TI box a few years ago. It was on a early '67. I used a semi-gloss as that's what it appeared like it was when I removed it from the car. It was the original TI unit according to the prior owner, since early 1968. Inside the original Delco module was still there. It's Power Transistors were dated before the car build, so it's probable the owner was correct.

I used the Eastwood gold cad coating on the rear cover, no time to send out one piece for plating.

After, but before changing the rear cover color. I used the K & B module.

p.s. I scraped the paint from the case for the ground lug.

I too can vouch for Mike's work. I had him restore my distributor and amp and not only did they both turn out like works of art, the car runs great and his prices were extremely reasonable.
