Repair of Pink Triangle Da Capo DAC

[Mooly]

Would need to see a circuit. The LM317 is an adjustable regulator.

Hi beatt2c,

Have your tried to remove the input cards - see if the 317 still runs hot once removed (Only remove with the Dacapo powered down).

If it now operates cool, then the DS9637 is damaged on the input card,

John

Hey John, long time no hear on this forum. Can you give us an update on the new products ? (Apologies for the thread hi jack.)

Dear John W & JonHarrison

Seasons greetings and many thanks for your replies which I'm afraid I missed at the time :-(

Since my last post ~ I have replaced the LM317 (with the heatsink) ~ however the DaCapo did not spring back to life. The unit is now with a work colleague who is more proficient than me but also busy ~ as soon as I am back at work after New Year I shall check with the input cards removed as you suggest.

FYI ~ the damage from the leaking electrolyte was on the audio side ~ and there was some damage to the audio leads.

Many thanks once again for your help and just to say that you have my respect and admiration for your wonderful creation which has given me such pleasure over the years. (So much so that I bought two ~ I lost my first one in 1994 due to divorce ~ the second helped revive my spirits after the trauma ~ now I'm struggling without it.)

Hi John,

I have left my Da Capo untouched for the last 6-7 years and naturally a few things went haywire

I googled and found alas! Someone repairs Pink Triangle! I am wondering if I could send my Da Capo for you to have a look and also repair?

It is probably yesterday's technology now but Da Capo was the closest my CD sounded like Vinyl.

Cheers,
Nelly from Oz

Sorry to drag this thread up again, but is there any chance someone has a circuit for this unit?

I have one in for repair which has very distorted output. A lot of the caps have leaked and the board is quite damaged but i do think it is resurrectable if only i had a 'Map'!!

Any help appreciated,

James.

Turn out that mine was beyond economical repair. In the end it was too hard to get it up and running again.

Contacted someone from the old Pink Triangle but he claimed he has lost all the schematics. Technology has moved on since then and I have to accept that it is no longer viable to fix the old Da Capo DAC. I auditioned some new DACs recently that sounded nice with balance input/outputs.

Hi John. I've sent you an email but thought I'd try this forum thingy. I was looking at picking up a DaCapo, but with my ham fisted soldering the capacitor repair may not be a good idea. Where are these new Dac's of yours? (A Frenchie has pinched the name Mephisto, BTW). Takes me nostalgically back to the days of Pink - awesome design ideas that never make it to production. Does the "Pop" still fry eggs? (And what happened to the 22 bit filter - you don't seem to include it on your list of favourites, and I'm assuming I'm not confusing it with the 24-22 bit which I have never seen, because the 22 was contemporary with the 1307 - and yours and my favourite at the time). (The "old Pink Triangle" would be AK presumably - and any claim of his to have lost something is entirely credible)
