I find cotton flour sacks dampen standing waves to superior effect than burlap.

I was hoping to find some quality 300VA+ toroids @ 18Vx18V (USA 120VAC), but seems Antek's are sold out.

Still -- I'd imagine the SS can get by just fine with a single 250VA donut, right? So, I'd have plenty of headroom going with two donuts @ 250VA?

I'm looking at 2 of the Avel Lindberg 250VA 18x18V.

Thanks again, ZM!

How closely should the Tokins be matched?

Do you think there's an advantage to the THF-51S for audio usage compared to the 2SK182?

Still no sign of the Cinemags shipping from Don Audio and they're not respnding to my queries.

Their website is now showing that there's a lead time of about 2months for new orders.

I suspect that they are waiting on the same production run that we have been discussing.

as close possible, hoping they will have closest transfer charactersistics; though, do not loose sleep about that - OS being follower, not so critical as with SITs used in arrangement having voltage gain

same for THF vs 2SK - in SInging Bush ( SIT having voltage gain) all measurements are showing that life is easier if using THF
in DEF OS ( SissySIT) , differences between THF and 2SK are lesser, and after some listening tests I made - exactly to determine possible differences - I didn't even bother to make measurements with 2SK

in 2 months, while waiting:
- you can make killer speakers
- you can read ton of books
-you can reach few K of km with bicycle
-all of above, together

life is good, while you're waiting on something, you can always find some immediate things for fun
