advice on 100w bias
100w bluesmaster advice - currently 1 fixed 10k L to 15k to ground - each tube 1r 2w. from pin 1 and 8 to ground - i would like to add another 10k L -- one for two outside 6L6 -- one for two inside 6L6 - Would I need to change the value of the 15k resistor {x2 } or just repeat what is already there?...

Re: lite 2b from ao-35
Thanks Mr. Fowler- Will check solder joints - I picked up a large roll of solder at a garage sale -tubes old radios etc. When I used the solder it did a dull bead ,so I switched back to tried and true. Might be the culprit -- thanks again - the pics are from an old iPod - will do better next time
