Here is a custom hand made single ended triode amplifier. 186 directly heated power triode in the output stage and 6CA7 6? 4 in triode mode for the driver. The driver stage is choke loaded for excellent low level dynamics.
It was made for 220-230 VAC line. This amp drives well most 8+ ohm speakers with good low response. I was able to drive 10' Tannoy Prestige Stirling speakers with the amplifer. Very similar to real 300B sound, perhaps even better. This item is in the category "Consumer Electronics\Vintage Electronics\Vintage Audio & Video\Vintage Amplifiers & Tube Amps". The seller is "ssho" and is located in this country: UA. This item can be shipped worldwide.
