| Collins 12Z Remote Amplifier | |

| First introduced to the broadcast market in 1944, the Collins 12Z four channel remote amplifier was used in thousands of stations throughout the country. This specimen came from WRR in Dallas, one of the first AM stations in the country. It was in pretty good shape when given to me but the masking tape on the front panel had deterioriated. I used an organic cleaner called "Goo Gone" to remove it from the panel. Then a bath with Zoom cleaner took off 40 years of nicotine! The amplifier operates either from internal batteries or AC. I plugged it in and ran a quick distortion test and it works just fine. | |

The Collins 212H-1 is a three channel transistorized remote amplifier introduced in 1961. It is powered by 14 'D' cell batteries and does not have a provision for external power. It is extremely simple to operate and was used by non-technical personel doing remotes. This specimen came from a Texas radio station. |
| Collins 212U-3 Remote Amplifier/Mixer | |
|
|
| Collins came up with the little 212Y remote amplifier in the late 1940s. It was only a single channel rig but could be used almost anywhere. Powered by either an external battery pack or AC line cord, the little remote was a big seller. To gain more flexibility in remotes by having two channels, it was mated with the 60H mixer. Together, the two rigs were called the 212U. It was offered in three different impedance variants, hence the suffix "1" for 30/50 ohms, "2" for 150 ohms or "3" for 200/250 ohms. My specimen was probably the only piece of Collins equipment owned by KGNC in Amarillo, Texas. Unfortunately I did not locate the canvas carrying case. I currently use this mixer in conjunction with my 32V-3 transmitter on AM. | |
