Does this have the Lundahl OPTs?Amp (TU-8900) sounds wonderful! Very easy to build but also very fun. Can't wait to fully break it in. Plenty of power also. Even with 2A3's I rarely turn it up halfway.
I asked TIM to compare ANK amp kit and TU-8900.
Sure I can do that. This is ANK Kit1-15. They are both very different... The ANK being tube rectified & a much more traditional single ended amp design. That said, I would rate your version of the TU-8900 as the superior product. More clarity, transparency, & detail. The ANK is very rich sounding but not nearly as versatile as what I'm experiencing with the Elekit.
I feel that the Audio Note copper caps are not a good match for the ANK. There is too much tendency for bloat in the bass & low mids. All that said, this is why I would like to purchase four Vcap CuTF .22uf 600v capacitors from you. I feel like those caps would be a better match for the circuit & allow me to do a better comparison between the two amps. The ANK as it is now, is very good for certain things but I do feel like oil capacitors are perhaps adding too much additional color.
I have a pair of Zu Audio DW2, and my space is 16'x10'. So, you're convinced that it'll get loud enough with the 2a3?The 8900 can drive a pair of Tekton Electon at 95 dB/w/m, in a 20x30 ft room, to fairly loud volume and provides nice music. In fact, using 2A3 tubes is good to a point that most music does not require the 300B.
The 8900, with Tekton Electon, cannot reach a sound level to reach your neighbour, though. Assuming that you are not in an apartment unit.
While spring is happening and outside chores still have to get done, I'm managing to find some time to progress with my TU-8900 build. Today I finished up the last of the resistor soldering on the main board, so now the caps and hardware will be next. The Ele-kit is starting to look like an amplifier!□ 3.3Ω(ORN‐ORN‐GLD‐GLD) 2pcs Takman 2 R129 /R229
