Heirloom item help please

It might be OK, but it may give you a slightly lower output.

[FrankSinatra]

Thanks Edward hopefully find out shortly.

[FrankSinatra]

My S5CM has arrived managed to get for £13, give it a go shortly.

[FrankSinatra]

All fitted sounds fantastic much better than the old cartridge, output is fine, perfect!

[FrankSinatra]

Funnily enough the sx6m arrived today, must have been delayed in postage, now I have an sc5m and an sx6m, which one does everyone think would be the better cartridge?

[Edward Huggins]

See again my earlier comments as to the difference. Whilst one may have a slightly higher output than the other, the variation in the actual sound quality will be very hard to detect through the rather basic amplifier and the type of speakers in your Radiogram.

[FrankSinatra]

Thanks Edward, I will leave the ceramic cartridge in place and keep the sx as spare.

[FrankSinatra]

Hello all, the left hand speaker has developed a slight crackle at high volume more like a static type sound when at certain high volume levels that gets worse as volume goes up.

Any ideas much appreciated,

[Edward Huggins]

Does the"crackle" appear on both Radio and Gram - or on Gram only?

[DMcMahon]

As far as I can see you never posted the requested photo showing the components on the underside of the amplifier chassis to help the Forum advise if any of your capacitors are the type that should be replaced for future reliability.

Particularly important for the coupling capacitors to the two EL84 output pentode valves, if you do post a photo, then please advise where those valves physically are on the photo, e.g. top left and bottom right corners etc.

I assume there is no label anywhere identifying the make/model name of the radiogram/stereogram ?

I’m a bit hesitant in taking out the chassis to be honest in case I damage it or it won’t go back as it should.

I will check the radio Edward and let you know I didn’t think about trying that.

[DMcMahon]

Understand your hesitancy.

[FrankSinatra]

It seems like it’s the same issue on radio or gram Edward at high volume levels on both but intermittent?

[Edward Huggins]

That seems to rule out a fault with the cartridge if it distorts on both sources. The amplifier will need attention to fault find. How do you feel about taking this on?

[FrankSinatra]

Depends what’s involved I suppose Edward I enjoy tinkering within my limits.
