Oh well...should have waited...I was so tempted by that buy 8 get 2 free auction. Anyway, my special little Bento box arrived for lunch today.
that's exactly Mr. Watanabe's way of packing .... I knew even without spotting Japan on that form
just for the record, got my package too from Watanabe. I´m not really into the project yet, but just read that normal FW claims might not sufficient😱
Heatsinks 😱30cm x 15cm with long 7cm Fins....they seem quite small in this context....🙂
anyway, will build (cool) iron pumpkin first 🙂

for what , now?
For trying out THF51-S and 2SK182ES from pras1107. 🙂
naah
curiosity is killing me at least 20 times per month ... showing how I'm dealing with suspense ....

double them , make monoblocks
or make Sissy^2SIT
🙂
indeed! : ) i´m really so in favour of "stereoblocks" that i didn´t thought of that. I could fan it in the build shown in pic, but just the flat inside of heatsink, that´ll be quite useless i guess. Really would like to have listening session before going to build monoblocks 😛. better half is not really fan of that.
but what is Sissy^2SIT?, 2 Channel Mono 🙂
bit early to ask, but is it possible to encrease bias from, say 1A up and just stay when heatsinks say stop? So in practice will it be the Offset/Bias/2Poti procedure, or is it more critical (regarding several voltage/current "windows", i´m not souvereign enough)
(first morning coffee nervous long lala, sorry)
Sissy^2 means Sissy squared or sissiest Sissy 
practically - SissySIT with decreased Iq
yes , you can do 1A , nothing more than 2 pots procedure
will do not just textual , I'm planning to make proper photo strip tutorial for assembly of amp , having few of them to make soon

match them tightly , and include 0R1 source resistors for each mosfet
THD spectra will stay practically the same , but amount of THD will change , no doubt
If I have a vgs difference of max 5mv(probably will be 2mv or so) at 1.7a on the irfps do I still need the source resistors?
Better safe than sorry
If you are sure in your matching (forbthis everything as in intended circuit,including time), then go for it

Pras1170 show big boxes with 100 pcs. of THF- 51 inside
To whom this may be of interest: I purchased from PRAS1170 four units of THF-51 for my diffamp-TOKIN amp. They seem very OK to me.
He accepts offers BTW. 😉

Well, it’s not me but my speakers that are asking for this 🙂

tnx Max
better late than never ........ and we are contemplating about that at least for a week
🙂
Forgive me Guapo... but a plethora might cut into my budget for adding a Turtle to my Iron Pumpkin. Still, a few more might not hurt.
pras1170 also has some THF-51T. Anyone have an idea what they are, and if they can be used in SissySIT with minimal effort?
I was able to find these two datasheets, but no mention of THF-51T, could it be fishy maybe? Re-labeled parts?
