I am interested in power soaking and have listened to some comparisons of attenuators. I like the sound of the THD Hot Plate, but cannot find the product being sold anymore. THD electronics website boasts of the product and when you go to buy it, it takes you to a very puzzling eBay page. Has the company folded? Can anyone suggest a better attenuator in the same price range? The Johan Segeborn YouTube video comparing the THD to a Jettenuator convinces me the THD is quite good. What happened? Note I have also read the cheap Bugera one has some negative reviews about it smoking.
