What are the input tubes  ?

[Tubedac123]

The input tubes are 6n1p tubes Duelund bypass capacitor mundorf capacitor Kiwami resistors j&k audio output transformer j&k power transformer j&k choke mill specs wire the chassis was made from aluminum from eBay the amp meter was from my Mr liang 845 tube amplifier the pre amp stage is a Lukasz Fikus schematic

These input tubes on post 1 are not 6N1P which dont have this bakelite base as these, they seems to be 6H8C/6H9C or other tube with bakelite base.

You are correct about the tubes it’s bean a long time

Do you have copper plates gm70 for sale

[Tubedac123]

I made a lot of stuff from lampizator I even made the speaker box with the real tweeter and Dayton point source 8 inch you see that cross over I made for the box  I didn’t use time alignment program i just play the same track over and over and keep changing capacitor and different types of choke then I get to a point that I am satisfied from listening  it sounds very realistic I was using the es9038 pro dac from buffalo with a tube output stage  the speaker wire is 4guage copper wire I am still trying to improve the sound every time I get a chance

Years a go I bought a copper plate pair at GSTube.com but it arrived damaged by the postal workers, the cathode tensioner wire came to loose.
But Andrey promptly refunded me.
