reliable dealers I don't know really

safest bet is buying an old tda1541a based cd-player
it might take you some time and patience, but in the 20-30 eur price range you can find sth, for 40-50 eur you don't need to be patient

here's a list of cd-players with that chip

Great, thanks wery much
must on the marked for a cd player

Hi Bjarne,

If you are not going to buy whole Cd player, please PM me, I have few different TDA1541 and TDA1541A as spares.
Some of TDA1541 were removed from players (as Marantz CD 94 and Philips CD960), some TDA1541A are new - I can check ones on my operational CD player to be sure those are OK.


Best regards
Saulius

I could use a tda1451a dac chip too. I've just ordered the red baron boards from Oliver.

decoupling caps... According to the spreadsheet BOM

Wima MKS02; 0.22µF 63V
Wima MKS02; 1µF 50V

these 16 caps can be replaced with ;

Cornell Dubilier 1µF/16V FCA 1210 caps- Mouser Part No.: 598-FCA1210C105M-G2

I only see 14 smt caps on the front of the board.
What don't I see?

 

[merlin2069er]

My boards arrived safely too. Thanks again.

Two of the 1uF are in the onboard I/V stage

I've got my tube output stage built (final oscons arrived today).

An externally hosted image should be here but it was not working when we last tested it.

I guess adding the filter would help this tube stage as well.

Mouser cart

I've got all the mouser parts (I can find on mouser) in this cart...

You guys are more than welcome to copy it... I haven't double checked it yet - but have removed parts from the original BOM (not needed with the latest mods).


Anyone have complete red baron build? I'd like to see them. I don't see how I can fit all these circuit boards into one enclosure.

Boards for the regs arrived Oliver, they look great!!..

Thanks,
Shane

Only one left!​

I guess the buffer on board isn't necessary if your using a tube output stage.

You have to choose the onboard I/V or an external e.g. Tube-I-zator, yes!

 

[merlin2069er]

Thanks. I've got my mini lampizator I'll use first.

757-2SK170BLF <- this is obsolete. What can I use in it's place?

JFET N-Ch SM Sig FET -50V NF 0.5dB -1.0nA -30V (757-2SK208-GRTE85LF) <- this ok?

Thanks.

You could order them at FETAudio as matched quad.
