Single Ended 300B Mono Blocks

Hi!

Just finished another set of 300B monos with 10Y driver.




A four chassis affair in my classic portrait style chassis:




Each mono block consists of the amp and a separate power supply.




Tango interstage and output transformers.




Of course with the ELROG ER300B as output tube.




Side views:





Yamamoto meter at the front to show the bias current of the output tube.




Best regards

Thomas

    Hi, is there a specific reason to display the bias current ? I assume it is rather a retro design objective. Or is it an ON/OFF indication ?
    Congratulation to the new owner, have fun !

      It was requested by the customer who commissioned the amps and it gives an indication of the health of the output tube

      With those thoriated tubes you hardly need an ON/OFF indicator :-0
