Is it worth me replacing the film capacitors as well? (I may remove them in any event to help me remove the TDA1541 as I have a socket on order to refit with it.)

Polystyrenes are incredibly reliable so long as you don’t over heat them. I’d steer clear

There's no point in replacing the bit decoupling caps around the DAC, the originals will be fine and are perfectly good.
I agree about replacing the tants though.

Great points made above - added to which, there is no 'wear-out' mechanism for film/foil caps like the polystyrene; also - there is only one new source left to my knowledge ( LCR, in south Wales). Which is sad, since it's about the finest practical dialectric of all.
NB- fatal damage to PS caps can occur from 80degC upward- keep your soldering iron well-away; and if working close-to, beware/always-inspect for solder splash that might have inadvertently hit (and shorted!) such caps.

Thanks guys.
Can you suggest some good tants to search for?

For anyone interested in TDA1541 vanilla and gucci output stages (with some mention of digital tweaks) here's two versions of Ben Duncan's Supertuning CD articles from HFN/RR and Electronics World.

I use a version of these. Soldering heatsinks.
I don't know why these are wet, though!

I have a TDA1541A (with Crown) from a retired Meridian D600 that's available if it would help.

Wow - thanks! Would you be prepared to sell it?

Hi Chris, short answer - yes, but probably best if you PM me.

OK thanks. I do have a possibility of another 206 that is very close in serial number to my own. Should know today about that one.

All they all single crown S1 chips?

I'm 99% sure the RCD-855 didn't come as standard with an S1.
But honestly, don't worry about fitting an S1 chip. The importance of having one is massively overstated. It's much more important to get the thing working again, with any DAC chip. Fit a socket and you can then easily upgrade in the future if you feel the urge.
The only version I'd actively avoid is the relaxed tolerance R1 variant.

I heard it on t'internet, it might be wrong. I think improvements to the output stage as per Ben Duncan's articles would probably make a bigger difference.
say it as it is
pfm Member
pretty sure the 855 and later 955 did not have S1 at least ones I had did not

Okay - so I have just bought another 206. I may end up keeping this one for parts, or using it as a bridge to get my player up and running, and then hopefully selling it on.
Unfortunately I am sentimentally attached to my 206.
