Bro, cant help you man. Sometimes they don want to ship bcos electronic component very hard to clear custom one. You import amp right? They let you do it because it looks and is an amp, cannot bluff. But all these tubes stuff, may not even board their plane bcos of products that may cause frequency interference. The second seller deliberately quote you high shipping to discourage you from buying. $150usd shipping for small things like that?? Bloody hell my THD 8ohm hotplate only cost $40usd to ship to SG. Sorry I dont dare to help bcos later you pay me money already, and middleman at US got problem ship back here, then I kena sai... Yah, dont try vpost for this one too. They may reject this and return to seller, bcos they also dont dare to bring the thing onto the plane. And you also don know if seller would refund you if item return to him. (vpost once told me they dont dare to offend the custom there. really, I spoken to the manager here. But in the end I get the thing I wanted bcos got maverick seller ga ga deliver items to me thru their local post, usps, and manage to escape checking. you have to nego with the private seller.)
