Default Re: ECC83 and Germanium diode to replace 7C6

Very neat job Peter - glad my original thread has proved helpful.

My EL84/EBL31 substitute was in use for some time and gave excellent service until I was able to obtain a sensibly priced EBL1 side-contact valve to convert to an EBL31 by fitting an octal base and correct sized 1/4" top cap. (All the so-called 'EBL31' valves sold by UK dealers are converted EBL1s - too tall to fit in the Ekco A22, and with a 3/8" top cap).

As you say, one of the benefits of this approach is that the chassis and valve-holder wiring is left intact so if the correct valve comes along at the right price, it will plug straight in.
