btw. - for all interested , packing and shipping is ongoing ..... you can expect soon e-mail with Tracking No.

Have about everything ready, just waiting for the boards to measure the lead spacings for some components, then I can trigger my shopping cart at Reichelt as well.

@ZM,
interesting to know, how many has you and will you ship (count please all)?
Hope for tomorrow that I can work again to the SissySIT. :-|

Greetings from Kasachstan. ;-)

well , classic case of injustice

even if better of two , SissySIT is still less popular than SIT-3

 

[indra1]

To be as popular requires a PapaSIT in it.

@ZM,

thanks!

 

[Dennis Hui]

Given there are only 250 or so SIT3, it seems likely the number of SissySITs
will catch up.

Got the Cinemags yesterday, so soon total Sissiness will take over
My M2s are quite good now after a long run in period, had the house for my self yesterday and played rock at life levels. Dont think I have ever heard and felt Sabbath Ironman (remast. vinyl) like this before. Will be fun to compare to SissySIT.

Hi all,

a little progress ... only a mechanical test. The little screws / washer will changed and the bracket will be sanded and black painted or should it let it silver (alu)?
The screws (M6 ISO 7380-2 A2 V2A) from the bracket to the heatsinks get also washers, M6 screws fits perfects between the fins of the heatsinks.

And now ... family, tomorrow is a mother day!

split washers everywhere

though , if you have standard wide case (Modushop? at least heatsinks are) , you'll have trouble with tight space in case , because of L brackets

Hi ZM,

thanks for your answer!

split washers everywhere

Yes, of course!

though , if you have standard wide case (Modushop? at least heatsinks are) , you'll have trouble with tight space in case , because of L brackets

Yes you're right it is a Modushop but it seems to fit, the rectifer will mounted on bottom in the front or at the front panel.
I think about a extra case for the PS only, so that I can use for other Papa amps.

Another question, is for Iq also possible 1A2 (need not so much wattage for my speaker), thanks?

 

[Zen Mod]

it's possible but I think THD spectra will be worse

try it an leave where you like it

maybe you'll need change of few resistors , strictly depending of Ugs of crazy one

@ZM,
I think about that!

Assembly of a new Pass Amps case has started:

(First inhabitant will be SissySIT)

Curently working on PSU:

Looking forward to M25 / SissySIT PCBs - have already measured and set aside two pairs of THF-51S / 2SJ201 ...

Best regards,

something's wrong with pics

 

[chede]

With the pics themselves or with what's pictured in the pictures ?

 

[Russellc]

Is there advantage to using 2SJ201 istead of IRF parts?

OK, on a different computer now, and here I get the same problem ...

Reposting, hope this will work better:
