Decca Record Player
I have recently acquired a dismantled but apparently complete record player. I am seeking help with identification/circuit details etc. There is a Decca transfer on the inside of the lid. The turntable is a Garrard but the chassis carries no identification. The valves from left to right are:- Brimar 6SL7GT, Mullard E?, Mullard EZ40. On the back of the base of the cabinet there is a brass plate which has "RECORD PLAYER SER. No 50042" stamped on it. I have attached images of the cabinet, turntable and chassis. Any help would be much appreciated.

Re: Decca Record Player
Yes, looks like the Panatrope circa 1953:-

Re: Decca Record Player
Many thanks. I have the data now as I have invested in Paul Stenning's discs. I am fairly new to this! Presumably the 6SL7GT is equivalent to the 6SL7 as the GT only refers to the envelope? With regard to the centre valve on the picture, the data lists this as a 6L6GA the one fitted is a Mullard E?? but the national valve museum does not list a Mullard equivalent to the 6L6GA. Any ideas?
Any further help or confirmation of the identity will be gratefully received! |

Re: Decca Record Player
My guess would be EL37.
If you look carefully around the glass envelope where it joins the base, you should find a code etched into the glass. Let us know what it is.... This should confirm whether it's EL37 ( or outside chance EL33 ) I haven't got one to hand at the minute to x-ref Andy |

Re: Decca Record Player
Hi,
The deck looks like the Garrard RC120 that I have here except that mine has a fixed headshell instead of a plug in one. Is it finished in brown mottled "hammerite"? Mine is. Cheers, Pete

Re: Decca Record Player
Thanks.
The valve has R62 and below it B312 etched in the glass above the base - difficult to read so may be minor errors. Yes the deck is finished in brown mottled hammerite. The head is maroon with "Decca" on it. The brass plate on the deck below the head says:- Model RC 111 Schedule 51500. Am I correct with regards the "GT" on the other valve? |

Hi Mark,
GT just means Glass, Tubular. Peter |

Re: Decca Record Player
Hi,
It's interesting that Decca and Garrard headshells were interchangeable. Unless Decca made them to fit other decks as a kind of 'upgrade', of course. Cheers, Pete

Re: Decca Record Player
If I remember rightly this model was designed to use the Decca "XMS" heads which are an early "magnetic" type with quite a low output. The first valve is a double triode and one half is used as a preamp for the XMS cartridge.
These heads are not at all suitable for "modern" records, having little if no compliance as the rubber innards will have perished. Looks like there is already a BSR cartridge in the headshell (there were two originally - brown for 78's and red for "microgroove"). The relatively high output of the BSR cartridge will need some "damping down" to interface with the original circuit unless this has already been done. Robert |

Re: Decca Record Player
Thanks for the help. Where do you get these codes from?

Re: Decca Record Player
Thanks - From the "B" in the second set of alphanumerics it would appear that the valve was made only a few miles from me in the Mullard works in Blackburn!
