Ford found out the hard way when they laid off hundreds of their engineers and let AI do their work. After a year or so of issues and numerous recalls they just recently had to rehire 350 of their senior engineers to fix AI's mess. Of course, it's possible that AI never got all the info it...

This is for the fellow asking for this.

All the E.C.I. tube radios (Couriers, Aircastles, Fannons, Realistics) had nine pin connectors for power. Depending on how the plug was wired it could power the radio with AC or DC.

Or you could just buy a complete kit from a place like Klondike Mikes.

That post is from 2014. If you click on his name you'll see he hasn't posted anything since 2017. He probably isn't on here anymore.

Here's some info on the difference in height of the two Astroplanes and some pics from an AV 101manual and a pdf.

I didn't realize you were from Australia. I remember reading that there were only 18 channels allowed there back then, and I remember CPI had their CP-180 model with 18 channels just for Australia.

The FCC allowed 40 channels in the beginning of 1977.

I think this is probably what you have already.

Here's the manual. Page 16 tells how the meter works and how to adjust it.

I haven't been on this site in a few years, I just signed on, and it came up to the main page, but it didn't let me into anything.

This may help you, the original Realistic Factory Service Manual for the TRC 458. It's the same radio as the 457 but doesn't have the clock. Also, the TRC 449 manual may help. It was the mobile version of the radio.

That was in the Cobras. The Presidents and Realistics already have it bolted to the heat sink.

The swap to the Sanyo 2SC2999E never much amounted to anything. Someone who didn't know how to read data sheets and didn't understand that there is no test standardization amongst transistor manufactures saw that the noise level was slightly lower than the 2SC1675 and 2SC1674 transistors and...

Something looks wrong with pin 10 of that chip, and it doesn't look like the chip is seated all the way into the socket on the one end.
