|Collins supplied a specially designed RF interconnecting cable to use with the exciter of the 30L1; typically the KWM-1. This cable was special as it presented 50 ohms to the input circuits at all times.
Also, on another W8JI related topic regarding the 30L1, the AC power cord and transformer have wiring issues that are potentially dangerous. Collins made some serious errors wiring the power transformer. For safety sake, please read the information on the following link to make sure your 30L1 isn't wired in a dangerous manner:

|This is a single tube, AM Broadcast Band Receiver. You will need a six volt battery (or 6 V dc power supply) and 22 to 27 V dc to power the plate. The 9 volt batteries in series works good for that.
You will also need high impedance headphones (2K-3K Ohms), a good antenna and an good ground to make it work.
It uses a four pin 200 type tube, though a 201 type tube can also be used.
