hey @thiefoflight I have that adapter and it's the one I had to rewire with a jumper in order to get it to properly work with a Decware unit that runs the heaters on AC,... just be aware,.. They assume that most all modern tube gear runs DC heaters which is def. NOT the case. I personally think the SN7 is not best suited for the BHK anyway.. BUT.. like anything in this hobby ymmv. PM me if you want, I can try to find the original correspondence I had with 1217 and exactly what I did,.. but essentially I had to cut the 9>7 trace and jumper 5>7,.. This is specifically for an AC heater circuit though, so just be aware..
The Supra's are excellent, a very clear sounding and engaging pre. Lifetime warranty, built like a tank. Not beautiful inside but purposefully built and the sound shows it! The Cortese has an excellent phono stage if you need one. I've had the opportunity to listen to a number of older Supra models (recently) verse my current Cortese and while they are all good and a little different, Mick's current circuit offerings, in my opinion, are def. a step up in terms of clarity and instrumental separation within the soundstage. Just very clear and concise without sound analytical. Very lifelike.
