Hi,

 

I am looking to replace the audio capacitors in my Atari 2600.

 

The existing ones are 820pf Polystyrene and I am trying to find a direct replacement I can order from RS or Mouser here in the UK. Can anyone give me a some guidance on what I can use to replace them?

 

I have been told I can use 820pf MLCC but do not know any more about the specs / datasheet in order to decide which to order.

 

Any help is greatly appreciated.

 

Alternatively does anyone in the UK do these kits like console5? https://console5.com/store/atari-2600-total-refresh-kit-new-capacitors.html 

 

The postage to the UK just makes ordering from those guys way too expensive.

 

Joe

It is always best to replace like for like if possible so for a polystyrene replacement try this, you will need to check their T's & Cs but as far as I know they will still accept phone orders paying by card without having to have an account, postage for orders under £30 ex vat is £3.50.

 

For ceramic try the AVX "skycap" series, or any AVX series, I would go for the X7R dielectric over the NPO but either will probably do and any voltage of 16V should be fine. You will more likely get a 10-20% tolerance on a ceramic cap than the 1% you will get from the polystyrene, although there are some ceramic that are 5%, it is unclear if the wider tolerance and therefore value range of the ceramic will have any noticeable effect on the sound.

Stargunner thank you very much. TBH i did not think it was possible to get a direct replacement any longer. I will order the ones you have suggested. 

 

Thanks again.

 

Joe
