Received my kit, thank you ZM. I have a nice matched pair of THF-51S from Pras, thank you.
No word from Cinemag, I hope they make a batch soon.
Now to think of a chassis and cooling, and order power supply parts.

Received my Kit #1 yesterday as well - thanks, ZenMod !
Currently soldering PSU ...
Also measuring lead spacings for a few components on PCBs, then hopefully final order for some capacitors and trimmers with proper orientation ... 🙂
Best regards,
Claas

I stopped caring about trimpots legs , are they in line or zigzag ...... I'm always making pcb with in line pattern and when I receive zigzags , even if I ordered other ones , I just line mid leg with tweezers
Well, I'm doing the same with the legs ... 🙂
Was thinking about orientation of the adjustment screw, so that ideally I can adjust from top of amp 😉 - sorry, probably didn't speak clearly enough ... 🙂

Started soldering resistors today and asked Donaudio for a volume discount. Let's see. Otherwise I could use my Jensen trannies...
ZM, is what is the Borbely buffer advantage if there is any? Walked through thread, didn't make me more clever.
Cheers

had that covered with THD tests either in Babelfish M25 thread or SissySIT thread
I believe I wrote that listenig confirmed what I saw in THD spectra - it brings some more sugar
I don't need more sugar , so I'm not using it
Borbely's WCF style buffer is showing its virtues under heavier loads , and here it is aroundish 1K, which isn't hard enough
try it ...... that's why I sent parts for it and those tiny 1pin sockets

@Juntuin, wow, that is a beautiful speaker! The diffuser looks like the top from the movie Inception ... are you sure you aren't dreaming a beautiful dream right now?
I had seen their "planets" before, but these are even cooler - I see they are called venus, I would have thought the ring of jupiter 🙂
You can never be sure 😉 too bad my Diy skills would never be able to build something like this.
I actually had "planets" years ago 🙂 these are step up in every aspect. Sometimes I find myself missing 15" drivers and horns, but man, these images so beautifully.
Hi just started assembling the Sissies, plowed through the tread but could not find how I should should orient the anode mark on the pc817 in relation to the markings on the pcbs?
No hurry to answer as Im on my 3. brandy so I will not solder more this evening 🙂 Listening to old Elvis records via SPU-A and my M2s 🙂

i once did this for getting my jensen trannies. The worst is:
-the are unfriendly, thinking that trannie is a bomb
-the air was filled with smell of bad instant soup.
: )
all around Europe - Customs are filled with staff fled from Securitate, a it looks
same arrogance , same absurd ignorance
apology to exception cases

Just to be clear on initial settings of the trimpots for Sissy. R6 should measure 100ohm between E-S and R7 0ohm betwee E-S while P1 0ohm between S-A (P1, 2k). For offset (P2, 10k) initial value not important?. (A,E,S according to Sissy diagram).

Take good care here, I failed first time and had to unsolder...
You have eight trimpots. 2x 20k, 2x 2k, 4x 100R. First determine which is which (measure). On the circuit diagram it says which is to go where.
Initial setting is also on notes for all of them. Find it on notes, all the information is there.
Last but not least mind the orientation, this was only clear to me later in the case of the buffer trimpots...
Make sure you have all of them correct and only then solder them in.
Edit: Offset is 10k of 20k pot so middle position initial setting.
