Old Soul

[myleftear]

This morning, it’s not important at all… it was just a brain-beep from lateyesterday and more like „are we many?“

 

[Zen Mod]

yes , you're many ........ and I'm just one , coping with deliveries to me ......... then deliveries to many .....

but, I'm happy , when I read that someone is happy after assembly

Old Soul wasn't choice of too many, I believe 7 packages all in all

Though, I believe little beast deserves plenty of attention - it's really unique in sound and most likely best one I saw in last 20 or 30 years, sound wise and technology wise, still worthy having Ge in name , simply because that Ge Bigun really dominating sound signature

 

[peppennino]

Me happy

Could you please describe that sound signature?

 

[Zen Mod]

I did, post #9

think - Nuovo Falcone

 

[peppennino]

Uhmmmmm.... SITish is a bit too concise

Anyway, after 16ys on this forum I solved (better than a supercomputer) the most important enigma: what is the ultimate question to the the Answer on Life, the Universe, and Everything:

IT

IS

- Would it drive an F4? 😀

 

[myleftear]

I got curious when you first postet about it, and got all the more curious—and dangerously impatient—right now…

Long before giving it an ear, I’m really happy for being able to build a beast as exotic as old soul! Thanks already, ZM!

I‘ll tell ya when I‘m there

Hardest part of the build: time’s up, not finished but must stop.

story of my life

have at least two heads, like Zaphod, to give me all wakoo ideas....... but not even 3 hands

 

[myleftear]

I think I can see what you mean.
Ideas is for sissies or something.
They never stop coming.
And I‘m not even close to your genious!

 

[peppennino]

but not even 3 hands

Implant it! 😀

Reminds me of total recalll…

Hi there,

I'm starting to collect parts. Can anyone suggest a part number (or the max dimensions I can use) for the small heatsinks on the PCB?

Thanks,
Dennis

 

[myleftear]

Sorry no (i’m lazy and got all the parts from great ZM), but you can deduct it from the bugs they have to cool (mouser - part id - package - heat-sink)
Don‘t understate them as one has to cool two buggers…

 

[myleftear]

Dennis, I have to apologize: tried to find it myself, utterly failed as mouser doesn't seem to have heat-sinks for the TO-225 package...

Dennis

The heatsinks are approximately 20mm tall, 12mm wide and the wings are 10mm'
I'll email a pic to you

Thanks Bob!

It is this heatsink:
ATS-PCB1014 Advanced Thermal Solutions | Mouser

Enough for the 0.45 W dissipation of BD pair.

After some unavoidable breaks (sleep/work/family) I'm kind of closing in again:

I swapped the bottom-plate with a customized, smaller one.
I rewired the whole thing with more reasonable wire.
I redid the back-plate because in the first round, speaker-posts and tranny collided.

And feel like being set back to field 1: It works just so-so!

(about 1 mm space between HA! and power-in and 1 mm between switch and tranny). IF I'd rotate HA! 90° (DC in on the bottom, DC out on the top), I'd save 20 mm! But I'd have to re-rebuild the plate and re-wire that rect-CRC-part, argh!

"should I stay or should I go?"

Then, the whole chassis-build is a quite fiddly task, it's almost impossible to access all screws with the board in place, not to speak about the task of setting bias etc. ... re-argh! (should have mounted the boards horizontally, which I didn't "because" the 300mm heatsink is too short for both board and bigun germanium bugger.

So, I'll reverse the §2 of the DIYA-constiturion:
NO GLORY, NO PORN

keep us in the loop

or should I say- feedback us
