Vacuum tube amplifier equipped with 6BM8 vacuum tubes from the former Yugoslavia.
Originally, I believe it was an ELEHOBBY kit, but it has been modified to ultralinear connection, and the first stage is a transistor.
Two sets of the kit's output transformers are used in parallel.
- Brand: ELEHOBBY
- Vacuum tube model: 6BM8x2
- Internal structure: Ultralinear connection, first stage transistor, parallel OPT
- Power supply: AC100V
- RCA input terminals: Speaker output terminals (8Ω)
Thank you for viewing.
This is a vacuum tube amplifier that a friend modified for me.
The 6BM8 is connected in ultralinear configuration, and the first stage uses a transistor for amplification.
The chassis interior is grounded with copper foil.
Two original output transformers are connected in parallel.
I've been told that these modifications allow for reproduction down to the low frequencies.
It was set up in the bedroom and used occasionally before the pandemic.
Sound output has been confirmed only.
