Romy,
Air core is ok, but. 1. Self inductance in an unmitigated field clumps. You can easily see this by unwinding a hockey puck style air core inductor and measuring the inductance with each turn removed. Never will you have the smooth loss of indu...

With regards to the links, as it happens, I totally agree that 15in Tannoy Reds struggle to handle complex music. The crossover is too simplistic and the cones too hard to control with a low power amp. Reds can be lovely in a simple vintage system bu...

[quote user="rafaroxlm"]As you may know the 7788 is a high transconductance pentode which should in theory be able to give higher audio resolution than say 12AX7, 6072 tubes in tube mic pre designs. On search here the 7788 was mention...

In my post above I have mention that Srajan is in a way a brainless parrot that repeats the heard and has no ability of desire to understand what was the noise about. His comments that 6E5P and E810F are “close electrical” is a good indication how it...

Here are some commentaries regarding my “End of Life" Phonostage.
The name of this phonostage derives from many factors. I am forty, winch it more or less a half live and in the first half I was playing a lot with different audio toys. The last 10 y...

Sorry for the delayed reply.
Oh yes. 50Hz is possible ; )
