Beomaster 5000 capacitor help

[martyn_mcg]

Hi,
I have a beomaster 5000 that I recapped a little while ago; although the sound was much improved I did hear a little strange distortion in the vocals on one of my records and it got me worried that I may have accidentally used one or two low ESR caps or something like that. That may also not be the case but it reminded me that a few people have said to make the BM5000 sound better to change some electrolytic caps for polypropylene? I believe at one time there was a post about this but I couldn’t find it in the archive. I wondered if anyone could point me in the direction of which caps in particular benefit from the swap and what brand/range of polypropylene caps I should be looking at?

Thanks,

Martyn

Caps in the sound path are usually small types. 1uF-10uf are used.

Good material for the sound path are WIMA MKS-2 types…

They are available in RM5 size, can substitute usually every electrolyth standard cap.

Available in 5%, 10% and 20% quality, some selected in non magnetic and 2% …

Usually in RED, they are a good replacement. Non magnetic and 2% are great… but you need a lot of material of 5% and a very good Cap tool to measure it. The magnetic types can be used for something elso in the power supply…

Low ESR in the sound path? Very bad idea…

Thank you for your help, i will look in to which capacitors i need for the signal path and try and source those WIMA replacments.
