From what I understand, that is not an issue. The setup has to do with toroid and wire size, if I was guessing. It is open to all.

Oh, yes, I meant in addition.
The problem is(one at least which I see) we need different secondary voltage for v3, v2 end F6, not only power rating(where you could combine two). So we do need at least three types transformers not talking about power yet...

Winding for specific voltages is still done on same setup, so not a big deal. Having to swicth between VA ratings is where the time and setup comes in to play.

sorry for my bad enghlish. maybe ? comming out a little wrong, but use imagination.. and youll know what i mean.


for turbo v3 what is the highest railvolt (within reason)? edit maybe trans. 45Vac? 35?
what bias is max disregard heatsink? think cryo... thinking about if we follow orig. schema will the rest of the parts cope ?

amp is teabag board, cascoded, max output trans with mur. liquid cooling
4x 100v 47000uf power supply mono. bying torrodial 1kva to 2,5 kva depending on output voltage.and if monoblocs or stereo.

speakers: seas exel diy 86db. sub long stoke 10 inch

want class a for maybe 100w and plenty ab
want class a for 50w plenty AB
want max class A

please comment in easy english pros and cons of this.
have 4 boards populated (no output trans or mur on board yet. from group buy by the exelence buzzman
will provide pics when i find the stupid cable to my cam.

please advice.
1. what would you build? why/ how. basic answer.

going to build 4 channels so maybe go for some different setups, for blindtest??
I dont know... any suggestions?

thanks

Good suggestion. However, for heavy items like transformers, the high shipping cost is always the deal breaker.

Right. Choosing the 500 (instead of 400) may be better since the F6 crowd can also participate. The 800 will be good for a mono V3 and likely be OK for a stereo V2. For people that want more juice for the V2, they can get two 500 instead one 800. My 2 cents.

I have opened GB for the transformers. Just list what you would like. When it is all said and done, we will figure it out.
@oiphy,
To get 100W, I would go for 26V sec(about 34V rails) and about 3-3.5A bias, assuming your sinks can take it. THis will give you 100W Class A and will push just about anything just fine. I have 27V rails on my V2 and 2A bias and have 50W.

Hi Buzz. I like the 26V secondary idea. Definitely shooting for the 100W mark. Would 34 volt rails be too high for the 50V Panasonic 10000uF caps I got from you in the first group buy? Thanks for the help!
