Maybe mount the SissySIT in a false ceiling, suck in outside air and dump it into the room. Would work nicely in winter, in summer, reverse the flow!
A 5-channel setup could very well heat the average apartment i'd reckon.
I'm thinking of foregoing the dual mono donuts and just go for a single 400VA core with 4x18V secondaries.
Unless you think it's a horrible idea?

one per side , two per case - perfect for monoblock
So you recommend installing a single channel per case with the board and Q4 mounted to one heatsink and the Q3/TH51S mounted remotely to the other?
beggars can't be choosy
just hope that watanabetomoaki is going to put them again on ebay
his auctions expired
dunno for other guy selling THF (pras... something) , is he confirmed - are his goods Real McCay ?
question for Soundhappy , he's current with these things .....

Simple solution if Tokin THF-51 is temporary not listed auction in Watanabetomoaki shop
ask about availability : click Contact Seller
link on this page :
1pcs NEC 2SC2558 NPN UHF RF Power Transistor (NOS) | eBay
and write him short message : You can at the same time make price offer
for how many SIT's You want buy.
In the past and today we have only this seller in Japan and was lucky verified by Mr Pass him self.
Today we can find other similar SIT's propositions in China by Pras and others....but is not verified source(s)
Conclusion : wait relisted THF-51 "buy it now" from Watanabetomoaki
or take risk and try from the other sellers if after transistors reception You test show very bad curves
no problem You ask Your money back...
if SIT's after tests are OK then....
Congratulations for NOS good Tokin SiT's source discovering 🙂 Kindest regards
I purchased four THF-51S from watanabetomoaki a day and a half ago before the auction expired, and I have not received a shipping confirmation yet.
I wonder what is up? Is he running low? If I don't hear from him in the next day or so, I will send him a message.

Last I saw, he had sold 78 out of 100 and the auction dried up... Wondering if he'll be back? Some others seem to have some, but these are not yet (to my knowledge) proven sources of legit products.
most probably Papa bought them all

though , I believe Papa is not wasting his time for anything which can't be made in at least 100pc series
that demands some 200 SITs , plus some for maintenance

watanabetomoaki has relisted THF51s.
In my search I found pras1107, of interest is that the same pictures are used on aliexpress. (same store front number embedded in the images.)
There are 2 other sellers, both selling for around $27 a piece which is 1/2 what watanabetomoaki is selling for. But as noted, there is no proof of authenticity with these other sellers yet.

I just pulled the plug
ordered THF51-S and 2SK182ES from pras1107
hopefully , we'll know authenticity of his parts in few weeks (expecting no less than 3 weeks)
it'll be good ..... that is good , considering quantity on his pictures .... it'll be plenty of new toyz for Greedy Boyz
