Hello. I am looking for some help here. I have acquired a lovely old 1975 Rank Arena C-1451. I am wanting to tune my VCR to channel 3. I have connected the VCR via RF out to antenna in, using a 75ohm -> 300ohm transformer. I simply cannot get the TV to tune the VCR. Attached are the pictures of the set up. There is no UHF dial on this TV. So I'm using VHF 3, however no picture. The VCR would have the in-built modulator so signal conversion would not be the issue? There is only one channel selector with a fine tune ring around it. Can someone assist me with some advice on how to tune these, I am totally at a loss. Thanks in advance[img][img][/img][/img], Mark

OK. first of all slide the switch on the antenna panel to the right.

With Ch3 selected on the tuner, AFT switched OFF and your VCR running, press and hold in the rim around the channel knob. Rotate it up to 10 complete turns clockwise. Stop when you tune a signal.

If you don't pick up anything, rotate it up to 10 turns anticlockwise, same applies.

You don't need to use an external balun, you can connect the inner conductor of the co-ax to the left hand screw point, slide the clamp to the left and use it to connect the outer conductor of the co-ax. Slide the switch to the left.

Oh yes, how do you know your VCR's RF modulator is outputting Ch3? Or even VHF for that matter? Not many brands sold in Australia were 3 - 4 switchable (JVC, Akai) most were 0 - 1 switchable (Panasonic and just about everyone else).
And you must have the VCR's "TV-VCR" switch on "VCR" for it to work. And of course the "VCR - Ext" input selector switch on Ext to connect your external source.

What make and model of VCR are you using for a modulator?

To do that you would have to cut off the connector on the end of the 75 ohm cable and strip back the insulation. Using the transformer you have is easier. I do believe that the switch is in the wrong position to use the 300 ohm terminals. So as irob2345 says, switch it to the other position.

Many if not most VCRs sold in the US could be switched between channel 3 and 4. Look on the back of the VCR for a switch.

Here is a diagram of how to use the antenna connections, this would have been on the back of your TV.
