Information

Some of the most expensive radios from the mid '50's through the '70's had an 'Automatic Tuning' feature. Typically, in Europe, these were top of the range Becker and Blaupunkt radios. In the US, Delco and Philco manufactured 'Wonderbar' radios as they were affectionately known where the automatic station search feature was started by simply hitting a large chrome bar, the 'Wonderbar', that ran across the whole width of the radio above the dial. It was made this way so the driver could search for favourite stations easily and without taking his eyes off the road. There's a Delco Wonderbar demo in the video below.  If yours has this feature, and you want to retain it, select this option and you will have the CORE upgrade plus Autotune.

The upgrade involves a full cosmetic restoration of the radio and the installation of an AM/FM 4 x 45W RMS Stereo radio unit which replaces the original electronics. An AUX input is fitted too. All the original controls including the band switch are serviced and integrated. The resulting radio looks and operates exactly like it should as a period correct device, but has up-to-date features and performance. Turn it on and it sounds great!

Please Note: As part of the upgrade, all the components of the Automatic Tuning mechanism will be cleaned, serviced and built into the upgraded radio. This mechanism is a complex arrangement of clockwork (see the video below), electromagnetic relays, mechanical switching, worm gears and a high power solenoid, and that's before we get into the electronics. All of these components need to be serviceable for the feature to be retained and spare parts are very hard to obtain. If these components in your radio are not serviceable, we will complete the CORE upgrade without integrating Autotune and refund the difference in price. On a positive note, we find that around eight out of ten autotune radios can be saved, so it's very probable that yours is one of them!

Additional options may be selected for increased functionality:

Bluetooth.        Full, totally legal, hands free telephony, audio streaming and voice control

USB                  Charges phone, tablet or laptop AND play MP3 files from a USB memory stick

DAB/DAB+      Receive DAB stations on your classic radio

Please Note: If purchased for use in the US we will substitute an HDR (High Definition Radio) unit for the DAB/DAB+ converter for at no extra cost. Simply select the DAB / HDR option as normal and we will make the necessary adjustments.

All of these additional options are fully integrated into the radio, so the existing radio controls are used to handle phone calls or move between audio tracks etc. 

The radio will be built to order according to your specifications.

If you have any special requirements with regard to the radio or your project schedule, just let us know and we'll do our best to accommodate.

Please allow 4 to 6 weeks from your radio being received at our workshop before we complete the work and get it back to you. We'll keep you informed of progress along the way.

Next Steps

Box up your radio very carefully and send it to us, including all the knobs, fascia and any other front panel parts. We will restore it, and install an AM/FM 4 x 45W RMS Stereo radio unit with AUX input.

You can go to our contact page to download and print off an address label, a packaging slip to pop in the box and a simple guide to packing your radio to make sure it gets to us safely.

Voltage and Polarity

Your car will have either a 6 Volt or a 12 Volt battery and it will be either Positive earth or Negative earth. We need to know the voltage and polarity of your car so we can build you a radio that will work in it.

Our standard build is for 12 Volt, Negative earth vehicles. If yours is NOT 12V Negative earth you will need to select the appropriate Voltage and Polarity from the drop down box and we will build a converter into your radio so it will work correctly in your car. 

Check your battery, or ask an engineer if you're not sure. Polarity refers to which terminal of the battery, positive or negative, is connected to the car body, and hence is the earth or ground terminal. 

Speakers

The converted radio can be used with up to 4 speakers, each driven by one of the 4 separate channels. However, it will operate perfectly well with the number of speakers you feel is correct for your car. If you use a single speaker, the unit will automatically blend Left and Right Stereo channels into a Mono feed so there will be no compromise in sound quality. Each time the radio is turned on it checks to see if there's a speaker attached to each channel and any unused channels are automatically switched off. This means that speakers can be added or removed without having to re-configure the radio in any way.

We would always recommend that new speakers are fitted with your converted radio. Go to our Accessories section to select from the high quality speakers we have on offer there. 

Aerial

Our AM, FM and DAB radio upgrades have all been optimised to operate using the original period aerial on the vehicle. No additional aerial, other than the original, is required. 

Please make sure the original aerial is functional and if telescopic, it's clean and operates smoothly. If you need to source an aerial, we have a number of options available depending on the age and type of car and whether you want hidden, in-cabin or a powered aerial. Check out our aerials in the 'Accessories' section here.

Installation and Operating Guide

A comprehensive installation and operating guide is supplied with every radio. This guide will be tailored to your individual set and will include full instructions for the operation of the radio, including any installed options.

Installation is straightforward, but we always recommend that it is carried out by a qualified and experienced engineer. However, if there are any issues or questions raised during installation we are happy to help, so please do get in touch.

Warranty

Your re-engineered and upgraded radio is covered by a comprehensive 1 year warranty from the date of service.  

Please be aware that our warranty is offered on the understanding that the set has been correctly installed in accordance with the installation guide supplied and has not been tampered with in any way.

If you have any problems with the radio at all, please do get in touch and we will work with you to find a resolution. Many issues can be solved on the phone, but if we do need to have the radio returned, we will arrange a collection at our expense. All you have to do is package it securely and hand it to the courier. We will repair the set and get it back to you as quickly as we can.

Because we focus on attention to detail and quality in everything we do, we have rarely had a radio returned. Consequently, we feel confident in offering our customers this comprehensive 1 year warranty. We want you to have total confidence in us and peace of mind when you purchase and enjoy your classic car radio upgrade.
