Sunvalley SV-S1616D [300B]

I've almost purchased the H-20-3.5U from Mr. Isao a few times, but the retail cost was too high unfortunately.
If the price in this kit will be competitive, I will surely go for this SV kit.
Another advantage is that the circuit should be designed around the 3.5K operating point.

Victor, you mention Tango doesn't manufacture anymore in Japan... is that true for ISO Transformers as well? I've purchased from them in the past and they shipped directly from Japan.
 
Wow, this is beyond my reach but I totally understand shipping has gone thru the roof and as a business you can only offset so much. I still think it’s a good kit to have for those that want to dabble in 300B and KT variants.

I already have EL34/KT66 amp so it makes sense for me to lean towards Elekit 8900 because I want to try 2A3.
