My P5b was fitted with a good looking Motorola which unfortunately I could only receive "Jimmy Young" on MW. So I sent it to a man who converted it to receive FM, AM and a slot for something called an Ipod. My problem is that the radio stations fade and the sound quality does not compare with my day car set. I have tuned the radio using the fine adjuster with little change. I was wondering if the aerial or speakers need a little TLC. Any thoughts would be appreciated.

John, I know exactly what you mean as I have had a similar conversion done on a radiomobile radio and was a bit disappointed with the sound quality. I have since come across a firm trading as tadpole radio who convert the controls of your old radio to work a modern unit which can be concealed elsewhere. This will then have stereo, iPod etc but will look original. I was thinking of one for my p5b coupe as a finishing touch. Worth a look. I think the price is around the £400 mark.

There is a massive fundamental problem called "the speaker". It was designed to work at low power and to reproduce 200-7kHz approximately.
There is an additional problem if the conversion uses any part of the original power amplifier, and that is the amplifier will also have designed in frequency limits similar to the speaker.
The end result is "period" sound. Not what we wanted?
Now that we are familiar with reasonable quality sound at extraordinary low prices, "period" is always going to sound miserable.
The solution is inevitably to hide a modern CD / radio / MP3 player somewhere. Glove box, under the parcel shelf etc.
Then there is the decision re speakers. For the absolutely minimally apparent system, you can with a lot of effort squeeze in two 6" split system speakers behind the front wall of the under dash parcel shelf. The tweeters can then be mounted just underneath the L glove box and by the brake warning light. For a more "surround" sound you can install a 9x6 full range speaker centrally in the original central rear parcel shelf speaker position.
For a near invisible "kick-ass" system, you can instead have two slimline 7" speakers mounted under the rear parcel shelf having made two sets of drilled speaker holes in the new parcel shelf vinyl covering.
And for added bass depth, a 10" compact slimline subwoofer system will fit behind the rear set.
It brings a broad grin to my face every time I put on Michael Jackson's Thriller, and does a beautiful job of Beethoven too.
If you want the original radio to work too, an RF cable splitter will allow you to have two radios running off the same aerial.

Valve set car radios. It reminded me of my 80 which I owned for about 20 years.It also had a valve set which took a while to warm up and it was always a great shock / surprise when it eventually came on (forgetting that I had turned it on).

Pretty impressive. I now need to totally rethink my sound system. Thanks to all for your constructive suggestions.
