These amps got finished in the last week of 2014. Another set of 300B mono blocks with 10Y as driver tube. The same configuration as the previously shown 10Y/300B. Only this time with Tamura F-5003 amorphous core output transformers.
I was never very fond of amorphous core transformers. Maybe this was mainly due to some listening sessions with systems which overly used amorphous core transformers throughout. So I decided to give it a try with just the output transformers on amorphous cores.
The driver stage is again a 10Y, transformer coupled with a Tango NC20 to the 300B grid. The amps can be operated from the same power supplies. But these new monos will later get a matching set of PSUs of their own.
Those Tamura transformers have a nice white/light grey finish. Unfortunately Tamura stopped production of a major part of their transformers last year, among them this line of amorphous core transformers. As was the case when Tango decided that they will go out of business, I also secured a stock of the Tamura types which were announced to be discontinued.
Stay tuned for an update on the sound of these amps and especially the amorphous core transformers.
Best regards
