Radio Caroline History: With a general shortage of money but a comprehensive
list of requirements, Peter Chicago scoured the USA for good quality equipment
and happened upon a Dallas radio museum who were prepared to sell him enough
kit to make a reasonable studio
For just a couple of 100 dollars he bought a pair of sturdy Gates CB 500 Turntables, a couple of Gates Mixers, Cart' machines and pair of Ampex Tape Recorders
Here's the tale of the Gates CB500 Turntables there after in Roy's own words:
1. Stripping down Deck 1
Dating from the early 1960's there was a sticker on one deck that linked it to the Mormon Church of America, they were acquired by Caroline, so ideal for the Viewpoint 963 service!
2. Turntable platter removed Deck 1
Taken aboard the Radio Caroline ship the Ross Revenge 1983, they were put in the Portacabin studio's on the rear deck, before being moved to the port side studio that later became the Dutch service
3. Turntable platter Deck 2
The decks were then moved again to the rear studio built by Peter Phillips for Caroline Overdrive, I think there is a picture of them in the rear studio at sea
After the raid on the Ross Revenge in1989 they were put back in to the Dutch studio, ideal as the mounting holes were still in the desk top
4. Compare turntable platters, Deck 2 left
When the Ross was towed into Granville Dock, Dover after going aground on the Goodwin Sands in 1990, they were in a bad state suffering when the ships generators were slowed down to the UK standard of 50 htz, as a consequence they ran slowly
Caroline had been given some better turntables, so they were removed & dumped in the old freezer/food store at the rear of the ship
5. Base underside Deck 1
They are very easy to pull apart & I only had to drill out a couple of seized screws. The chassis' were bead blasted & powder coated by a local firm that refurbish alloy wheels for a cost of thirty pounds, turning them round in three weeks
6. Lid from a tin can ideal template for the cutting center hole was the for the job
When you had your held your * Caroline Reunion at the King Charles Hotel in Gillingham they sold at the auction for fifty pounds to Graham L Hall, I bought them from him for the same amount (* 12th August 2000)
7. Strobe markings to set the turntable speed
They sat in my storeroom for a few years until I started to refurbish them last year (2013)
8. Piece of 2x2 to mount cutting tool ... | 9. ... produced a perfect circle |
I bought new & one side with adhesive applied pre-cut felt squares, I purchased three in case of a mishap in cutting
10. 24 hours drying before removing excess glue
11. Deck 1 back from being repainted
12. Deck 1, note the Gates name plate, it's missing from Deck 2
13. Deck 1 partly re-assembled with a new American mains supply lead & plug
14. Base plate underside anotated with model & seriel number
I didn't repaint the undersides as Caroline's engineers annotated the base plates, removing it would lose some of the history
15. Stop/Start switching arrangement, believe felt pen markings added by Caroline
16. Previous owners
17. Stop/Start switching remote engineering markings
18. Stop/Start switching remote engineering markings, alternative view
I have photographs of the mercury tube's which are under the big red on/off buttons, these were rejoined with new wiring
I tracked down some new old stock in the USA but it's illegal to import mercury on aircraft with aluminum skins
19. 2" of wire replaced which had badly corroded on both decks
20. Original manufacturers sticker, new ones were sourced but not fitted
21. Deck 2 almost complete
22. Deck 2 almost complete, alternative view
23. Deck 1, waiting for the tone arm to be fitted
24. Deck 1 almost complete
25. Deck 2 almost complete, alternative view
26. Wooden base fitted for tone arm mount
Thus not disturbing the mount, the original wooden Microtrack 306 16" tone arms were broken beyond repair & very hard to find, even more so when you want a pair!
But I hope to find a pair to fit in the future
27. Tone arm fitted to Deck 1
Instead I've fitted Astatic Tone Arms spotted in an on-line auction
28. Deck 2 with tone arm fitted
I powered both decks up and they both ran well after being left for 15 years, there was no smoke or anything amiss just a smooth turning platter
Next jobs are to fit the wiring to the arms and cartridges. Hopefully new capstans being machined for the motors to achieve the correct speed will be finished soon

Properly cared for vintage Gates Turntables are highly collectible, & command good prices
These once prolific transcription units were at most American Radio Stations, the CB series was a proffered BBC Network & Local Radio Station deck in the UK
