I have a classic, almost cult like, tube amplifier built by Jim Nicholls. My friend had this built in, at least it was completed, in July, 2014. After paying over $1800 for it, he never used it. You would have to know my friend to understand. I had a technician friend of mine bring it up an his Variac, slowly, and check the voltages. It came up just fine and everything works as it should. I have played it for about an hour through my test speakers and it sounds great. I’m going to try it with the Forte’ II’s later. Power tubes are GE black plate 6BG6’s with exposed grid, basically a 6L6. Driver and phase inverters are the plentiful and cheap 6SN7. It uses two 5U4 GB rectifiers, hence the large power transformer. This is basically a highly modified Magnavox pull. I do have some correspondence paperwork between Jim and my friend Richard I will include. It gives some unique insight on the building process including the installation of a stand-by switch. Even though it was built over four years ago, it ie essentially new. It probably needs a bit of breaking in I would think. One nice feature is he installed a detachable power cord. I would like $750 for it plus shipping via FedEx ground. I will try to post some pictures, thanks!
