Thank you for viewing.
This is a vacuum tube amplifier that a friend modified for me.
The 6BM8s are connected in ultra-triode mode, and the first stage amplifies with 6U6s.
The output transformer was replaced with a larger one than the original, and furthermore, two were connected in parallel.
I heard that these modifications allow for the reproduction of low frequencies.
It was installed in a warehouse/office and was occasionally used until before the coronavirus pandemic.
Only the sound output and bias have been adjusted.
