Two non working Dansettes
Hello
I have a Dansette Conquest Auto and a Bermuda which are both non working. Both of the valves looked damaged so i bough new ones and replaced them however it still makes no sound. I have a feeling that the problem with the conquest is the cartridge which the terminals had fallen off the wires so i just have to solder them back on and plug them back into the cartridge, however I'm completely stumped by the Bermuda. I've tried using a wire from the tape out in the back to a separate amplifier however no sound was created as well. Is there any parts that usually go bad which i could test with a multimeter or any tests i could run to test if the amplifiers inside them are faulty. Could you also help with with which valves i need. I got a replacement EL84 for the Bermuda and a 6AQ5 for the Conquest as the other 6AT6 looked fine. I believe these are the correct valves but if they aren't please can you assist me on which ones i need. Thanks so much |

Re: Two non working Dansettes
It seems that you have an early model 2 valve Conquest. The valves are all the correct types. It's easy to jump to obvious consclusions, but it could be that both cartridges have failed. You will be able to get a more modern stereo-compatible, medium-output cartridge for the Conquest, but the high-output cartridge you need for the Berumuda are no longer made. You will need to buy a modern clone/copy type. We can advise as to the types you need. Both will be quite expensive £35-40 each. it is also likely that the valves you replaced may have been OK.

Re: Two non working Dansettes
Before you go buying new pickup cartridges, I would get the amplifiers working first.
If you touch the wires on the back of the pickup do you get any buzzing noise from the speaker.. What experience do you have with working with valve equipment, and what tools test equipment have you got. Mike Last edited by crackle; 29th Apr 2018 at 5:23 pm. |

Re: Two non working Dansettes
So far I've used a multimeter to test the components but they looked and seemed fine. I've had other amplifiers and audio equipment apart before but not valve amplifiers.
I did have on the Conquest however, I put in the new valves and turned it on, smelled warm then massive sparks came from the valve so I have doubts that they work anymore. |

Re: Two non working Dansettes
There were several different amps fitted in the Dansette Conquest. What's the valve line up in yours?

Re: Two non working Dansettes
From what I can glean here, the OP has an early 2 valve Conquest version - using 6AT6 and 6AQ5. As to "sparks coming from the valve" I cannot tell why, as valves do not usually spark and, if so, then will have likely died. I still have a feeling that if the OP had "grid tested" the amps for functionality, he would have found that in both players the cartridges would have been at fault and the valves possibly were quite OK. As this is first time the OP has worked on valved equipment he should read the useful Sticky above here on reviving old record players. Alternatively he could get these looked at by specialists in Norfolk.

Re: Two non working Dansettes
Or perhaps a specialist in Suffolk like yourself?

Re: Two non working Dansettes
Graham, I am more than willing to drive over to Beccles on a no obligation basis and assist if the OP so wishes!

Re: Two non working Dansettes
That sounds like a good idea. I'd be interested to hear what you find.
