Chris, I do not think that you will see me to think about transformers for other channels. I do not think that what I do will be some kind of resolution for Amorphous vs. Nickel transformers: in my care it will be a different amp with different out tube and differently loaded. The subject of faster core vs. more idle plate is very interesting but I am not the one to address it. I do want to do for a SLIGHTLY slower core, but not too much slower, then increase damping and power, will see where it will lead. I have a hunch the it might be a good direction for a limited bandwidth
About the transformer. I was thinking about it a lot. It will be 70% Nickel with limited inductance to support 200 cycles at 50mA. 20:1. It will load the ~1250R plate of YO186 to ~6K. I have no idea if it will be good and if the YO186 even the tube that will give any interesting sound. Here is what I was thinking:
In my priory list are the “small” 4V DTH tubes like RE604, AD1, PX4 and those ghost-like YO186 since they were damped to my head and might be a “cheap” replacement of the imposable to get good RE604, AD1, PX4. If my project with small DHT will go south then I will go for full-size DTH but the high-impedance, like 10Y. Many experiences people advised me that I will not see in those high-impedance tubes the “tacky” and “overly romantic” qualities that I do not like in some DHT. I kind of would like to have “clean” and “neutral” sound, the one similar in “cleanness” to 6C33C, sine it will be DSET I do not see any problem with high OPT ratio. If the 10Y will not go as well then I will jump into the common 2A3/300B/45 wagon. If all falls then I will return to my ½ 6C33C… that it absolutely securest assurance of the result that I accept.
So, how to put one ass to all DHT transformers? I find a solution. In fact I did not find it, it just came itself. I spoke with Dave Slagle, inquiring what he can do and he told that his design implies the field interchangeable coils and adjustable gaps. That is a very cool solution for me. He also assured me that the assembling and disassembling of his transformer is Morons-complained, which is perfect for me. So, he will wind a base transformer and I might just get from him more windings if I need them.
Regarding you to hear the installment? Be my quest. From what you heard before my playback nowdays is 342 light miles ahead and I am very comfortable to play it "as is" without any MF modifications and with the Amorphous magnetiks. I afraid that MF modifications will do some downtime foe a month or so, unless my unicorn YO186 hit the mark from a first try…The Cat
