Hi all!
I've built my tube amp based on schematic of AN Conquest.
Yesterday I made a modification suggested by a friend.
I removed C and R form the first cathode of 6SN7 and put there a 2,4V battery :)
I was a little afraid but everything's o.k.
amp didn't blow :) and sounds a little bit hmmm smoth and airy.
but I consider if it is safe fo amplifier? what with charging this NiCd battery? will it be charge by current (about 5mA)? |

Thaaaaat's fine! I like batteries and leds. 5mA is a charging current that a 300mah battery can easily handle so it should be fine there.
Ciao

Pawcio,
This battery maybe give you a little too high bias.
Try to found 1.2V single cell NiCad. |

what kind of led would you suggest? (color?)

1,2V? Isn't it too low?
normally I had about 2V on cathode resistor (320R) |
