Lorain Electronics Corporation (LEC)
This advertisement is from a September 1954 Lorain County Radio Corp. publication entitled "Study Guide for Third Class Radio-Telephone Operator Permit." The MC-261 unit in the tall cabinet on the right in the advertisement was built by General Electric in Syracuse, NY. In 1959, when the Archivist first went to work as a design engineer for General Electric, equipment of this vintage had already been replaced by newer designs, but GE later supplied Lorain Electronics Corp. (LEC) with several versions of newer VHF-FM receiver and transmitter chassis for shipboard installations and also, I believe, for the LEC 14 station automated VHF-FM network .
This short item is from a history of GE's mobile radio business: May, 1955 - Cruise of the yacht, Cappy, on the Great Lakes to survey coverage furnished by Lorain County Radio Corporation's, 250 Watt GE station, at Lorain, Ohio.
The Lorain equipment images (1940s-50s)
shown below are in a roughly chronological order.

 Captain (?) - Steamer John T. Hutchinson (WA 6537) using Radio-Telephone |  This Model LRK 3 channel receiver is probably from the 1950s, and was intended as a monitor receiver. It was likely used on shore by companies and crew families as it runs on 120VAC and not the normal 120VDC boat voltage. Click on the image for a larger view and images of the inside.

The
control head in the picture
of the left immediately above is for a dual MF/HF and VHF-FM radio-telephone
installation. Here's an enlarged
image of and more information about the control head showing the channel numbers and
their purpose.
Here are some images of Lorain gear found recently in a Chicago surplus warehouse.
Some comments about the Chicago gear from Charles C. Reynolds: The LC100M8 was still around when I started so I did have some limited experience servicing it. It was superseded by the LC1008A and the the LC150-10A which was much more "modern" with 6146A's as finals. There would have been two or three remote subsets or control heads for the M8. Typically, one would be at the conning position near the front window of the pilot house. Another would be in the Captain's room. If it had a third subset, it would be near the chart desk or chart room adjacent to the pilot house. The eight modules are indeed complete receiver strips for each of the eight channels. See the Great Lakes page for the channel and frequency information. The control in the cabinet was a local control for servicing purposes. I believe the M8 used VOX rather than PTT. The 8A and 10A introduced PTT. The use of VOX resulted in a habit of all transmissions beginning with ahhhh to allow time for the VOX to key the transmitter. There are still a couple of old timers that still do it on VHF today even though they have been using PTT for the last 30+ years. The transmitter was designed to load a wire antenna of about 60'. The M8 was AC. Most of the boats were had only DC power at the time so there would have been an external Carter rotary converter to produce AC. Some of the earlier equipment used the ship's DC plus a dynamotor to get high voltage for the finals.
All of the Lorain Electronics Sales
& Service Dept. personnel quite at the end of 1980 shortly
after the purchase of LEC by Oakmont Electronics. Most of the
technicians when to work for ITT-Mackay Marine and became the Great
Lakes Depot of same. In 1985 the remaining contents of 2307
Leavitt Rd. were sold and Lorain Electronics closed it's doors.
